## Guides: buying a mobile game
- [Mobile game development cost in 2026](https://dfygames.com/guides/mobile-game-development-cost) ([markdown](https://dfygames.com/guides/mobile-game-development-cost.md)): A simple casual mobile game typically costs $15,000 to $35,000 at a development studio, a casual game with progression $30,000 to $150,000, and a mid-core RPG or strategy game $300,000 or more. DFY Games builds a focused one-loop iOS and Android game from $499 by fixing the scope to one polished core mechanic.
- [How to hire a mobile game developer](https://dfygames.com/guides/hire-a-mobile-game-developer) ([markdown](https://dfygames.com/guides/hire-a-mobile-game-developer.md)): You have three routes: a freelancer (lowest hourly rate, but you manage the project), a full studio (a complete team, usually $15,000 and up for a casual game), or a done-for-you service that sells a fixed-scope game at a fixed price. Whichever you choose, get the scope, timeline, price and ownership terms in writing before you pay.
- [How do mobile games make money?](https://dfygames.com/guides/how-mobile-games-make-money) ([markdown](https://dfygames.com/guides/how-mobile-games-make-money.md)): Most free mobile games earn from two sources: ads, which pay per eligible served impression (at a $10 eCPM, one cent per ad, though rates vary widely by country and format), and optional in-app purchases such as coins, power-ups and remove-ads, bought by a small share of players. Monthly revenue is roughly active players × what each player is worth in ads and purchases, minus the stores' fee on purchases, and finding those players has its own acquisition cost.
- [Mobile game development timeline: how long launch takes](https://dfygames.com/guides/mobile-game-timeline) ([markdown](https://dfygames.com/guides/mobile-game-timeline.md)): Build time and launch time run on different clocks. A DFY Core game targets a submission-ready build in 10 business days after payment, complete intake and blueprint approval; Advanced reaches a polished first playable in 10 business days and normally completes within 30 days. After that, new personal Google Play accounts need a closed test with at least 12 opted-in testers for 14 days, and both stores review on their own schedule.
- [Game template vs custom game vs a done-for-you package](https://dfygames.com/guides/game-build-options) ([markdown](https://dfygames.com/guides/game-build-options.md)): A game template is the cheapest route if you can reskin it, publish it and support it yourself, and you accept the seller's license terms on the code. A fully custom studio build gives the most freedom at the highest cost; one 2026 studio estimate puts a simple casual game at $15,000-$35,000. A done-for-you package sits between them: a fixed scope and price, original assets you own after payment, and the studio handling the build and submission.
- [Mobile game design document template: what to put in your brief](https://dfygames.com/guides/mobile-game-brief-template) ([markdown](https://dfygames.com/guides/mobile-game-brief-template.md)): A useful mobile game brief fits on two pages: the core loop in one sentence, the player, the first minute, the screens, progression, monetization, art direction and what is out of scope. This guide fills one in completely for our example word game concept and gives a blank checklist you can copy, with extra notes for puzzle, word and arcade genres.
- [DFY Games process: what happens in your first ten business days](https://dfygames.com/guides/dfy-game-build-process) ([markdown](https://dfygames.com/guides/dfy-game-build-process.md)): Before day 0 you complete intake and payment and the studio prepares a blueprint. Day 1 locks the mechanic, screens, art and monetization; days 2-3 bring a playable core; days 4-7 add art, UI, sound, progression and monetization; days 8-9 are device QA and the policy checklist; day 10 delivers submission-ready builds and the store kit for Core. Advanced uses the same ten days to reach a polished first playable, then normally finishes within 30 days.

## Guides by game type
### Sort puzzle games ([service page](https://dfygames.com/games/sort-puzzle))
- [Sort puzzle game development: cost and scope](https://dfygames.com/guides/sort-puzzle-cost) ([markdown](https://dfygames.com/guides/sort-puzzle-cost.md)): A sort puzzle with one rule, one theme and up to 100 generated, QA-checked levels fits the DFY Games Core package at $499, or $1,299 with a 30-day launch campaign. Adding a second mechanic, chapters or daily challenges moves it to Advanced + Launch at $2,999. For comparison, studios quote $15,000 to $35,000 for a simple casual game and $80,000 to $250,000 for a puzzle game with light live operations.
- [What a $499 sort puzzle includes](https://dfygames.com/guides/sort-puzzle-scope) ([markdown](https://dfygames.com/guides/sort-puzzle-scope.md)): A $499 Core sort puzzle includes one written sorting rule, one visual theme, up to 100 levels where generation and QA allow, about ten screens, a rewarded hint, interstitials between levels, up to two simple purchases and a store kit. Revisions are unlimited inside the approved blueprint until first submission; a new rule, mode or backend feature moves the brief to Advanced or a separate quote.

### Endless runner games ([service page](https://dfygames.com/games/endless-runner))
- [Endless runner game development: cost and scope](https://dfygames.com/guides/endless-runner-cost) ([markdown](https://dfygames.com/guides/endless-runner-cost.md)): An endless runner with one environment, one endless mode, a compact obstacle set, cosmetic skins and a rewarded revive fits the DFY Games Core package at $499, or $1,299 with launch campaigns. Multiple worlds, characters with abilities, missions or an upgrade tree move it to Advanced + Launch at $2,999. Studio estimates for a hyper-casual playable MVP start around $4,000 to $12,000 and a simple casual game runs $15,000 to $35,000.
- [How to brief an endless runner](https://dfygames.com/guides/runner-brief) ([markdown](https://dfygames.com/guides/runner-brief.md)): Brief an endless runner by writing down the controls (each gesture and what it does), every obstacle with the move that beats it and how it is telegraphed, and how speed should rise over a run. Then judge the playable checkpoint on feel: whether a new player survives the first 30 seconds, whether deaths feel fair and whether near misses read as skill.

### Idle tycoon games ([service page](https://dfygames.com/games/idle-tycoon))
- [Idle game development: cost and scope](https://dfygames.com/guides/idle-game-cost) ([markdown](https://dfygames.com/guides/idle-game-cost.md)): An idle or tycoon game with one resource loop, one main scene, an upgrade ladder, capped offline earnings and a simple milestone or reset fits the DFY Games Core package at $499, or $1,299 with a 30-day launch campaign. Prestige layers, multiple currencies, managers, missions and timed events make it an Advanced + Launch build at $2,999. Studios typically quote $30,000 to $150,000 for a casual game with progression.
- [Scope an idle game economy before you commission it](https://dfygames.com/guides/idle-economy-scope) ([markdown](https://dfygames.com/guides/idle-economy-scope.md)): Before you commission an idle game, put its economy on one sheet: each generator's base cost, cost multiplier per level, output and unlock condition, plus milestone bonuses and an offline cap. If the sheet has one currency and fits on a screen, it fits a Core build; if it needs a second currency, prestige or several linked production chains, plan for Advanced.

### Merge games ([service page](https://dfygames.com/games/merge))
- [Merge game development: cost and scope](https://dfygames.com/guides/merge-game-cost) ([markdown](https://dfygames.com/guides/merge-game-cost.md)): A merge game with one board, one primary merge chain, simple orders and a finite progression path fits the DFY Games Core package at $499, or $1,299 with launch campaigns. Quests, inventories, energy timers, several chains and events make it an Advanced + Launch build at $2,999, and ongoing live operations are quoted separately. Studios typically quote $30,000 to $150,000 for a casual game with progression.
- [What belongs in a merge game MVP](https://dfygames.com/guides/merge-mvp-scope) ([markdown](https://dfygames.com/guides/merge-mvp-scope.md)): A merge game MVP needs one board, one complete merge chain of around six tiers, a generator that spawns the first item, orders that ask for items from the chain and a finite goal such as restoring one town. Leave out quests, inventory, multiple chains, events and accounts; they can be added later as an Advanced upgrade or a separate quote once players respond.

### Arcade sports games ([service page](https://dfygames.com/games/arcade-sports))
- [Arcade sports game development: cost and scope](https://dfygames.com/guides/arcade-sports-cost) ([markdown](https://dfygames.com/guides/arcade-sports-cost.md)): A single-mode arcade sports game (one sport gesture, one arena, score chasing and cosmetic unlocks) fits the $499 Core Game package, or $1,299 with a 30-day launch campaign. More arenas, modes, characters or a season structure fit Advanced Game + Launch at $2,999. Simulation physics, real league or player licenses and realtime multiplayer are custom work; studios estimate $15,000 to $35,000 even for a simple casual game.
- [Brief an original arcade sports game](https://dfygames.com/guides/arcade-sports-brief) ([markdown](https://dfygames.com/guides/arcade-sports-brief.md)): A good arcade sports brief describes one gesture in enough detail that a developer can build it without guessing: what the thumb does, what the ball does in response, what counts as a miss and how the first 30 seconds teach it. Add an originality check (no real leagues, teams, players or logos) and a scope check (one arena, one mode) and the idea usually fits the $499 Core Game package.

### Tower defense games ([service page](https://dfygames.com/games/tower-defense))
- [Tower defense game development: cost and scope](https://dfygames.com/guides/tower-defense-cost) ([markdown](https://dfygames.com/guides/tower-defense-cost.md)): A compact tower defense game with one environment family, roughly three tower types, basic waves and straightforward upgrades fits the $499 Core Game package. Multiple maps, a hero or ability system, bosses and a persistent metagame fit Advanced Game + Launch at $2,999, with a first playable in 10 business days and the full build within 30 days. Studios quote $30,000 to $150,000 for casual games with progression and $300,000 or more for mid-core strategy.
- [Tower defense MVP: the smallest useful launch](https://dfygames.com/guides/tower-defense-mvp) ([markdown](https://dfygames.com/guides/tower-defense-mvp.md)): The smallest tower defense game worth launching has one environment family, about three towers that each counter a different enemy, three or four enemy types and a compact set of stages that introduce them one at a time. That fits the $499 Core Game package. Choose Advanced Game + Launch ($2,999) only when your test depends on multiple maps, heroes, bosses or a persistent metagame; PvP and user-made maps need a custom quote.

### Cozy simulation games ([service page](https://dfygames.com/games/cozy-sim))
- [Cozy simulation game development: cost and scope](https://dfygames.com/guides/cozy-simulation-cost) ([markdown](https://dfygames.com/guides/cozy-simulation-cost.md)): A cozy game built on one loop in one room, such as decorating a single space or growing a bounded set of plants, can fit the $499 Core Game package. Connecting gardening, a decor economy, several rooms and seasons, as in our example cozy concept, is Advanced Game + Launch at $2,999. Simulation with needs, schedules or visiting friends is a custom quote. Cost follows asset counts, which multiply quickly in this genre.
- [Cozy game scope without the endless wishlist](https://dfygames.com/guides/cozy-sim-scope) ([markdown](https://dfygames.com/guides/cozy-sim-scope.md)): Keep a cozy game bounded by listing every room and every interaction in it, then asking one question of each: does this need a new rule in the code, or only new art and data? New art inside an existing system is a decorative choice and rarely changes the package. A new rule is a system; one loop fits Core at $499, two to four connected systems fit Advanced at $2,999.

### Word game games ([service page](https://dfygames.com/games/word-trivia))
- [Word and trivia game development: cost and scope](https://dfygames.com/guides/word-game-cost) ([markdown](https://dfygames.com/guides/word-game-cost.md)): A single-mode word or trivia game with a fixed category set, local streaks and a substantial offline content bank fits the $499 Core Game package, and word games are one of the best fits for Core. Daily challenges, multiple modes, content packs, leaderboards or cloud content fit Advanced Game + Launch at $2,999. The content itself (word lists and trivia questions) has its own license and QA cost, which buyers often miss.
- [Who supplies the words in a commissioned word game?](https://dfygames.com/guides/word-game-content) ([markdown](https://dfygames.com/guides/word-game-content.md)): Either side can supply the words, but the brief has to say who. Common routes are an open word list with a permissive license, a licensed dictionary, an open trivia database (often share-alike) or content written for the game. Original content made for your project is yours after full payment; third-party lists keep their own licenses. Whoever supplies it, the bank needs profanity filtering, fact-checking and a plan for updates.

### Block puzzle games ([service page](https://dfygames.com/games/block-puzzle))
- [Block puzzle game development: cost and scope](https://dfygames.com/guides/block-puzzle-cost) ([markdown](https://dfygames.com/guides/block-puzzle-cost.md)): A basic block puzzle (one board, one placement rule, an endless score mode, a best score and a rewarded continue) fits our $499 Core Game package, with a submission-ready iOS and Android build targeted in 10 business days after payment, completed intake and blueprint approval. Adding a goal-based level mode, a world map, a coin economy and an analytics event map moves it to Advanced Game + Launch at $2,999. For context, one studio's 2026 estimate puts a simple casual game at $15,000 to $35,000 and a puzzle with light live-ops at $80,000 to $250,000.
- [Define an original block puzzle brief](https://dfygames.com/guides/block-puzzle-brief) ([markdown](https://dfygames.com/guides/block-puzzle-brief.md)): An original block puzzle brief describes your board, pieces, rules and feedback in your own words and gives the game its own name, art, sound and store look. Placing pieces to clear lines is a shared genre idea, but a famous game's name, logo, piece colors and screen layout are not yours to reuse, and a lawyer should check anything that comes close before launch.

### Space shooter games ([service page](https://dfygames.com/games/space-shooter))
- [Space shooter game development: cost and scope](https://dfygames.com/guides/space-shooter-cost) ([markdown](https://dfygames.com/guides/space-shooter-cost.md)): A space shooter with one ship, one mode, one deep-space environment, a curated set of enemy waves, a few pattern-based bosses and a simple upgrade ladder fits our $499 Core Game package; with 16 launch creatives and 30 days of campaign management it is $1,299. Several maps, distinct enemy classes, an upgrade tree and missions move it to Advanced Game + Launch at $2,999, and online co-op or versus play needs a custom quote.
- [What a small mobile shooter should launch with](https://dfygames.com/guides/shooter-first-release) ([markdown](https://dfygames.com/guides/shooter-first-release.md)): A small mobile shooter should launch with one ship, one complete run of waves that teaches each enemy before combining them, at least one boss, a short upgrade ladder and a rewarded revive. Before submission it should hold its target frame rate on the cheapest phone in your test set during the busiest wave and the boss fight. New ships, modes and events can wait until players show what they want more of.

### Arcade racer games ([service page](https://dfygames.com/games/racing))
- [How to scope an arcade racing game](https://dfygames.com/guides/racing-game-scope) ([markdown](https://dfygames.com/guides/racing-game-scope.md)): Scope an arcade racing game by fixing four things first: the handling model (usually one simplified input, such as hold to drift and release to boost), the number of tracks, the number of vehicles and how players race (time trial, AI rivals or online). One track, one vehicle and one time-trial or basic opponent mode fits our $499 Core Game; several tracks and cars with AI rivals, upgrades and cup progression fit Advanced Game + Launch at $2,999, and online racing gets a custom quote.
- [How much does an arcade racing game cost?](https://dfygames.com/guides/racing-game-cost) ([markdown](https://dfygames.com/guides/racing-game-cost.md)): A one-track arcade racer with one car, one time-trial or basic opponent mode and local best times fits our $499 Core Game package, with a submission-ready build targeted in 10 business days after payment, intake and blueprint approval. A multi-track brief with several cars, AI rivals, upgrades and cup progression fits Advanced Game + Launch at $2,999, within 30 days for the full build. For comparison, one studio's 2026 estimate puts a casual game with progression at $30,000 to $150,000.

### Pixel platformer games ([service page](https://dfygames.com/games/platformer))
- [Platformer game development: cost and scope](https://dfygames.com/guides/platformer-cost) ([markdown](https://dfygames.com/guides/platformer-cost.md)): A one-world mobile platformer with one character, checkpoints, collectibles and roughly 15-25 short levels fits the $499 Core Game package. Several worlds, a larger enemy roster, power-ups and bosses fit Advanced Game + Launch at $2,999. A large interconnected exploration map, multiplayer or a level editor needs a custom quote; studio estimates for casual games with progression run $30,000 to $150,000.
- [Mobile platformer controls: what to test before commissioning](https://dfygames.com/guides/platformer-mobile-controls) ([markdown](https://dfygames.com/guides/platformer-mobile-controls.md)): Before you commission a mobile platformer, agree how its touch controls will be tested: input delay filmed on a real phone, jump buffering, coyote time, button size and placement in the thumb zones, and behavior on small and large screens. Ask for a recorded checkpoint with taps visible that shows each of these, and play the build yourself on your own phone.

### Hero battler RPG games ([service page](https://dfygames.com/games/rpg))
- [RPG game development: cost and scope](https://dfygames.com/guides/rpg-cost) ([markdown](https://dfygames.com/guides/rpg-cost.md)): A small RPG-lite with one area, basic combat and a short quest line can fit Core Game at $499. A bounded turn-based hero battler with several heroes, gear and a campaign map fits Advanced Game + Launch at $2,999. Open worlds, large story campaigns, PvP or guilds need a custom quote, and one studio's 2026 estimate for mid-core RPGs is $300,000 to $1,000,000 or more.
- [Buy a useful RPG vertical slice before a larger build](https://dfygames.com/guides/rpg-vertical-slice) ([markdown](https://dfygames.com/guides/rpg-vertical-slice.md)): A useful RPG vertical slice is a thin piece of the game at final quality: one complete battle loop, one full progression step and just enough content to repeat it, with everything else deferred. Agree the battle, progression and content matrix and written acceptance criteria before work starts, so you can judge the slice on facts before committing a larger budget.

### Cooking rush games ([service page](https://dfygames.com/games/cooking))
- [Cooking game development: cost and scope](https://dfygames.com/guides/cooking-game-cost) ([markdown](https://dfygames.com/guides/cooking-game-cost.md)): A cooking game with one kitchen, a short ingredient list and one order loop fits Core Game at $499, or Core Game + Launch at $1,299 with 30 days of campaigns. Several restaurants, recipe trees and a deeper upgrade economy fit Advanced Game + Launch at $2,999. Studio estimates for casual games with progression run $30,000 to $150,000.
- [Scope a cooking game without content overload](https://dfygames.com/guides/cooking-game-scope) ([markdown](https://dfygames.com/guides/cooking-game-scope.md)): Scope a cooking game by counting stations, ingredients and recipes in one matrix, because content multiplies: every new ingredient adds art, timing rules and recipe combinations to test. Lock one kitchen's matrix in the blueprint, see a single order loop working from order to tip, and add dishes or restaurants only after that loop is fun.

## Guides: buying a custom app
- [Mobile app development cost: a practical scope guide](https://dfygames.com/guides/mobile-app-development-cost) ([markdown](https://dfygames.com/guides/mobile-app-development-cost.md)): Mobile app development cost follows scope: how many screens and user roles the app has, whether data lives on a server, and how many outside systems it connects to. A single-role utility that stores data on the phone is the cheapest kind of app; accounts, payments, an admin dashboard and each integration add build and test work. After launch, budget for Apple's $99 yearly developer fee, Google Play's $25 one-time fee, hosting if you have a backend, and maintenance.
- [App source code ownership: who owns the code and art after a build](https://dfygames.com/guides/code-art-ownership) ([markdown](https://dfygames.com/guides/code-art-ownership.md)): With DFY Games, you receive the project files and the original assets made for your app or game once it is fully paid, at final handover. Third-party software, SDKs, fonts and stock assets keep their own license terms, and for game builds the studio's reusable tools stay with the studio while you get a perpetual license to use them inside your game. Have a lawyer review any development contract before you sign it.
- [App development brief template: screens, roles and integrations](https://dfygames.com/guides/app-brief-template) ([markdown](https://dfygames.com/guides/app-brief-template.md)): A good app development brief names the problem, the types of user (roles), every screen each role needs, the outside systems the app connects to, and the personal data it stores. Fill in the worksheets below and a developer can return a written scope and quote instead of a guess.
- [App maintenance cost: what you pay for after delivery](https://dfygames.com/guides/app-game-maintenance) ([markdown](https://dfygames.com/guides/app-game-maintenance.md)): After delivery, the fixed fees are small: Apple's developer program costs $99 a year and Google Play charges $25 once. The real app maintenance cost is work: updating for new iOS and Android requirements and store policy changes, SDK updates, hosting and monitoring if the product has a server, and user support. A single-player game with local saves needs far less upkeep than an app with accounts, payments and integrations.
- [Before you submit: a mobile app launch checklist](https://dfygames.com/guides/mobile-launch-checklist) ([markdown](https://dfygames.com/guides/mobile-launch-checklist.md)): Before you submit, check four groups of items: accounts (Apple Developer Program, Google Play Console and closed-testing eligibility), the build (current SDK targets, on-device testing, reviewer access), disclosures (privacy policy link, Apple's privacy details, Google's Data safety form, families rules if children may play) and the store page. Approval remains Apple's and Google's decision.

## Guides by app type
### Booking apps ([service page](https://dfygames.com/apps/booking))
- [Booking app development cost: what changes the quote](https://dfygames.com/guides/booking-app-cost) ([markdown](https://dfygames.com/guides/booking-app-cost.md)): Most of a booking app's cost sits around the booking screen: how availability is calculated, whether you take deposits, how reminders go out and what your staff need to manage. One location with one calendar and card deposits is a small scope; every extra staff schedule, resource, location or outside system adds build and test work. DFY Games prices booking apps from a written scope with stated assumptions, so the quote follows the scope you approve.
- [Custom booking app vs scheduling software: how to decide](https://dfygames.com/guides/booking-build-vs-buy) ([markdown](https://dfygames.com/guides/booking-build-vs-buy.md)): Buy existing scheduling software when your booking rules are common, you need it running this week and a subscription is cheaper than owning code over several years. Build a custom booking app when booking is part of a larger product, your availability rules do not fit standard tools, or you need your own app in the stores connected to systems you already run. Many businesses should start with software and revisit the question once they hit its limits.
- [Booking app integrations: a commissioning checklist for one workflow](https://dfygames.com/guides/booking-app-integrations) ([markdown](https://dfygames.com/guides/booking-app-integrations.md)): A booking app usually connects to four outside systems: a calendar, a payment processor, a notification channel (push, email or SMS) and sometimes a customer database. Each connection can fail on its own, so a good scope names what happens when the calendar sync is late, a payment succeeds without a booking, a cancellation needs a refund, or a reminder never arrives. Use the checklist below when you commission the app: to brief a developer, review a quote and test the build before you accept it.

### Membership apps ([service page](https://dfygames.com/apps/membership))
- [Membership app development cost: what to include](https://dfygames.com/guides/membership-app-cost) ([markdown](https://dfygames.com/guides/membership-app-cost.md)): A membership app's cost depends on which of three jobs it does: a digital member card for physical access and perks, gated digital content, or recurring renewals inside the app. A card-only app is the smallest scope; content adds an admin and hosting; renewals add billing logic and, for digital content sold in the app, the stores' in-app purchase rules. DFY Games quotes membership apps from a written scope rather than a fixed price.
- [Custom membership app vs community platform: which fits](https://dfygames.com/guides/membership-build-vs-buy) ([markdown](https://dfygames.com/guides/membership-build-vs-buy.md)): A hosted community platform is usually the better start when you are still testing whether people will pay and engage: it is live quickly and someone else maintains it. A custom membership app fits when membership is tied to physical access, other systems or a product experience the platform cannot model, and when you want the member list, payment account and app listing fully in your own name. Ask any platform how you would leave before you join.
- [Gym and creator membership app: scope and cost of version one](https://dfygames.com/guides/member-app-mvp) ([markdown](https://dfygames.com/guides/member-app-mvp.md)): A first gym or creator membership app is cheapest when it does three jobs well: delivers your workouts or classes, runs simple challenges, and controls who gets access. Gym apps tied to physical access usually take payment outside the store systems, while creator apps selling digital workout subscriptions in the app generally must use in-app purchase. Health data, wearables and personalised plans add review and compliance work, so leave them out of version one unless they are the product.

### Marketplace MVPs ([service page](https://dfygames.com/apps/marketplace))
- [Marketplace app development cost: scoping a bounded MVP](https://dfygames.com/guides/marketplace-mvp-cost) ([markdown](https://dfygames.com/guides/marketplace-mvp-cost.md)): A marketplace app costs more than a single-sided app because you are building two user journeys, an admin tool and a money flow that has to handle refunds and payouts. The cheapest credible version is one category, one city or niche, one transaction type and a small admin panel. We quote marketplaces individually after discovery, and the written scope lists every assumption behind the number.
- [Marketplace MVP features: the minimum marketplace worth testing](https://dfygames.com/guides/marketplace-mvp-features) ([markdown](https://dfygames.com/guides/marketplace-mvp-features.md)): The minimum marketplace worth testing completes one transaction end to end: a seller lists, a buyer finds and pays, the seller delivers, the platform releases the payout and either side can raise a problem. If your first version stops before payment, you are testing a directory, which is cheaper and sometimes the right first step, but it will not tell you whether people will pay through you.
- [Marketplace app payment integration: a buyer's responsibility checklist](https://dfygames.com/guides/marketplace-payment-scope) ([markdown](https://dfygames.com/guides/marketplace-payment-scope.md)): Before anyone can quote a marketplace payment integration, you need to decide when money is taken, when it is released, who can refund it and who handles disputes and payouts. Most marketplaces use a payment provider built for platforms that pay third parties, and the app builds the flows, admin actions and notifications around it. Check the payment provider's terms and the Apple and Google payment rules for your exact case; this guide is planning help, not legal or financial advice.

### Internal operations apps ([service page](https://dfygames.com/apps/internal-operations))
- [Inventory app scope and cost: one workflow, four tradeoffs](https://dfygames.com/guides/inventory-app-scope) ([markdown](https://dfygames.com/guides/inventory-app-scope.md)): A custom inventory app makes sense when one location or one team has a stock workflow that off-the-shelf tools handle badly, such as counting in a van, checking kit in and out or receiving deliveries against a list. Keep the first version to that one workflow. Barcode scanning, offline sync, user permissions and reporting are the four choices that move the quote most. If you need accounting, purchasing and multi-warehouse planning, buy inventory or ERP software instead.
- [Replace spreadsheet with app, or fix the spreadsheet first?](https://dfygames.com/guides/spreadsheet-to-app) ([markdown](https://dfygames.com/guides/spreadsheet-to-app.md)): Replace a spreadsheet with an app when the problem is how data gets in (people on phones, in the field, typing into the wrong cell) or who can change it, and when the time lost each week is large enough to justify a build. If the problem is only messy columns or missing formulas, improve the spreadsheet first; it is cheaper and often enough. The worksheet in this guide helps you put a number on the time at stake before you ask for a quote.
- [Offline checklist app development: a field-app brief](https://dfygames.com/guides/offline-field-app-brief) ([markdown](https://dfygames.com/guides/offline-field-app-brief.md)): An offline checklist app lets field staff complete inspections, photos and signatures with no signal and syncs everything when the connection returns. The work is in the rules around sync: how uploads retry, what happens when two people edit the same job, who can change a signed record and how every change is logged. Write those rules into your brief and a studio can quote it accurately.

### Education apps ([service page](https://dfygames.com/apps/education))
- [Education app development cost for a course companion](https://dfygames.com/guides/education-app-cost) ([markdown](https://dfygames.com/guides/education-app-cost.md)): An education app's cost depends less on the subject than on who the learners are and what the app has to manage. A course companion for adults (lessons, quizzes, progress, one admin) is the smallest useful build; school systems with classes, teachers, parents and children's data are a different, much larger product. DFY Games quotes each app after a short scoping questionnaire, so you get a written scope with assumptions before any number.
- [Course app vs mobile website: which fits the learner?](https://dfygames.com/guides/course-app-vs-web) ([markdown](https://dfygames.com/guides/course-app-vs-web.md)): Choose a mobile website when learners study at a desk, arrive from a link and finish in one sitting. Choose a course app when they learn in short sessions away from Wi-Fi, need reminders to come back, or track progress over weeks. Many course owners run both from one content source: the website sells and onboards, the app is where practice happens.
- [Education app MVP features: a first-release checklist](https://dfygames.com/guides/learning-app-scope) ([markdown](https://dfygames.com/guides/learning-app-scope.md)): A first-release learning app needs four working parts: lessons learners can open, quizzes that check understanding, progress that survives a phone change, and an authoring tool so you can publish without a developer. Decide two things before scoping: who is allowed to see which lessons, and where your content lives so you can always export it.

### Calculators and configurators ([service page](https://dfygames.com/apps/calculator-configurator))
- [Custom calculator app development cost and scope](https://dfygames.com/guides/calculator-app-cost) ([markdown](https://dfygames.com/guides/calculator-app-cost.md)): A custom calculator app costs more than its few screens suggest, because the work sits in the pricing rules, the data behind them and what happens to the result (a saved quote, a lead in your CRM, a PDF). A generic formula with no business rules rarely justifies a custom build. DFY Games scopes calculator and configurator apps from a written brief and quotes them after a short questionnaire.
- [Web calculator vs native app: which suits your customers?](https://dfygames.com/guides/calculator-web-vs-app) ([markdown](https://dfygames.com/guides/calculator-web-vs-app.md)): For customers who find you once and want a quick estimate, a web calculator is usually the better choice: no install, shared by link, updated instantly. A native app fits people who use the calculator repeatedly, need it offline or save work to an account, which more often describes your own sales team or trade customers than first-time visitors.
- [Pricing configurator app development: from spreadsheet to app](https://dfygames.com/guides/pricing-configurator-brief) ([markdown](https://dfygames.com/guides/pricing-configurator-brief.md)): To turn a pricing spreadsheet into a reliable configurator, write down four things before any build: who owns each formula, how and when numbers are rounded, which inputs are valid, and what the edge cases should produce. Then give the developer a table of real test cases with correct totals. The app is finished when it matches every row.

### Event and loyalty apps ([service page](https://dfygames.com/apps/event-loyalty))
- [Loyalty app scope and cost: one reward loop and its tradeoffs](https://dfygames.com/guides/loyalty-app-scope) ([markdown](https://dfygames.com/guides/loyalty-app-scope.md)): A first loyalty app needs one loop: a customer earns a stamp or points for a visit, unlocks a reward and redeems it while staff confirm. The cost depends mostly on how earning is verified (staff scan versus a POS integration), how many redemption rules you need, and how much the admin panel has to do. DFY quotes loyalty apps after a written scope; there is no fixed package price.
- [Event app first release: what to scope for the day itself](https://dfygames.com/guides/event-app-scope) ([markdown](https://dfygames.com/guides/event-app-scope.md)): A first event app should cover what attendees need on the day: the schedule, a personal agenda, venue information, announcements and check-in against a ticket list you already have. Ticketing, live streaming and attendee networking are each large enough to be separate projects, so the first release links to existing tools for them.
- [Custom loyalty app vs loyalty platform: build or buy?](https://dfygames.com/guides/loyalty-build-vs-buy) ([markdown](https://dfygames.com/guides/loyalty-build-vs-buy.md)): Use an existing rewards platform or your POS vendor's loyalty add-on when a standard points or stamp program fits and the subscription cost is acceptable over several years. Commission a custom loyalty app when your rules are unusual, you need loyalty inside a wider app, or you want the member data and integrations in systems you control. Compare both over three years, not on the first invoice.

### Custom utility apps ([service page](https://dfygames.com/apps/custom-utility))
- [Utility app scope and cost: how to scope one clear job](https://dfygames.com/guides/utility-app-scope) ([markdown](https://dfygames.com/guides/utility-app-scope.md)): A good utility app does one job you can describe in a sentence, such as scan a code and log it, remind someone to do a task, or track a number over time. Its cost depends on how many workflows it has, whether data syncs between devices or people, and which phone permissions and roles it needs. DFY quotes utility apps after a written scope.
- [Local app vs cloud app: choosing where your data lives](https://dfygames.com/guides/local-vs-cloud-app) ([markdown](https://dfygames.com/guides/local-vs-cloud-app.md)): A local-only app keeps data on the phone: no login, no server bill and a simpler privacy story, but data is lost with the device unless it is backed up, and nothing is shared. A cloud-backed app adds accounts, a server and ongoing hosting costs, and in return gives backup, multiple devices and sharing. Choose by whether more than one person or device needs the data.
- [Habit tracker app development: a brief without overbuilding](https://dfygames.com/guides/habit-tracker-brief) ([markdown](https://dfygames.com/guides/habit-tracker-brief.md)): A first habit tracker needs a short list of habits, a daily check-off, reminders and clear streak rules, with history on the device. Social features, coaching, wearables and AI suggestions can wait. Habit trackers are a crowded category, so test demand with a prototype or a waitlist before paying for a full build. DFY quotes habit tracker apps after a written scope.
