Gym apps and creator apps start from different places
This guide covers one narrow case: a membership app for a gym, studio or fitness creator, where members pay for access and the app is how they use it. It covers classes, workout videos and programs, simple challenges, member cards and the payment rules that decide how members pay.
It does not cover broader fitness products: a workout tracking platform with an exercise database, wearable and health data integrations, nutrition tracking, personalised training plans or live-streamed classes. Those are larger builds with their own compliance and review work. If your idea fits the narrow case, our membership app development page shows what a first version usually contains.
| Gym or studio | Fitness creator | |
|---|---|---|
| What members pay for | Access to a place, classes and coaches | Programs, workout videos, a community and the creator |
| Main screens | Member card, class timetable and booking, announcements | Program library, workout player, progress, challenges |
| Usual payment route | Card processor or front desk, since access is used in person | Store in-app subscriptions when sold in the app |
| Admin needs | Members, classes, check-ins, announcements | Content uploads, program schedules, challenges, subscribers |
| Biggest scope risk | Class booking rules and door check-in | Video hosting and a growing content library |
Content: workouts, programs and classes
Decide what a workout is in your app. A video with a title is simple. A structured workout with exercises, sets, reps, rest timers and substitutions is a data model that someone has to fill in for every session, and the admin to manage it becomes a product of its own. Many creators start with video-led sessions grouped into programs and add structured workouts later.
- Program library grouped by goal, level or length.
- Workout player with video, a timer and a done button.
- Simple progress: sessions completed, current streak, programs finished.
- Downloads for offline use in gyms with poor signal (adds storage and access checks).
- Admin for uploading videos and scheduling new programs.
Keep claims about results out of the app copy and store listing. Describe what the program contains rather than what it will do for someone's body, and add a plain note that members should check with a professional if they have health concerns.
Challenges that keep members coming back
Challenges give members a reason to open the app this week. They do not need wearables or sensors to work: a challenge can count completed in-app workouts, gym check-ins or entries the member logs themselves.
| Challenge type | How progress is counted | Scope note |
|---|---|---|
| Streak | Workouts completed on consecutive days or weeks | Small: uses data the app already has |
| Check-in target | Gym visits in a month, from the door scanner | Small if check-in exists |
| Program completion | All sessions in a program finished | Small |
| Group leaderboard | Points from workouts or check-ins, ranked | Medium: needs rules, privacy settings and cheating limits |
| Self-logged results | Member enters a time or weight | Medium: needs validation and moderation if public |
Leaderboards with self-logged numbers invite disputes, so keep the first version to counts the app records itself.
Membership access and store payment rules
Access control decides who sees what, and the payment rules decide how they pay for it. Google Play's Payments policy names gym memberships among the physical services that must not use Google Play billing, and lists fitness among the subscription services that must use it. Apple's App Review Guidelines draw a similar line between physical goods and services used outside the app (section 3.1.3(e)) and digital content unlocked inside it (section 3.1.1), and allow other payment methods for real-time one-to-one services such as personal training (section 3.1.3(d)), while one-to-few and one-to-many live services must use in-app purchase.
In practice, a gym selling door access can usually take payment by card or at the desk and let members sign in to the app. A creator selling a monthly workout subscription in the app generally needs in-app purchase on both stores, and pays the stores' commission. A business doing both needs to scope both routes and keep members' access in sync.

What to leave out of version one
- Wearable and health data integrations (Apple Health, Health Connect, watches). They need extra permissions, privacy disclosures and testing on devices, and the stores review health data use closely.
- Personalised plans that adapt to a member's health information, which move the app toward health and compliance territory.
- Nutrition tracking and food databases.
- In-app chat between members, which needs moderation and reporting tools.
- Live streaming of classes, which adds video infrastructure and different store payment rules for group sessions.
Each of these can come later once members are using the core app. Compliance is one of the main price drivers on any app, and health data is where it starts to apply.
Two example first-version scopes
| Area | Gym or studio app | Creator app |
|---|---|---|
| Member screens | Sign-in, member card with rotating QR, class timetable, book or cancel a class, my bookings, announcements, challenges, profile | Sign-in and subscribe, program library, program detail, workout player, progress and streak, challenges, profile and subscription settings |
| Staff or admin | Web dashboard for members, classes, check-ins and announcements; scanner view for the front desk | Web dashboard for videos, programs, challenges and subscriber list |
| Roles | Member, front desk, coach, owner | Subscriber, creator or admin |
| Integrations | Card processor for memberships, push, email | Store in-app subscriptions on both platforms, video hosting, push, email |
| Out of scope | Wearables, nutrition, live streaming, member chat | Wearables, nutrition, live streaming, member chat |
Either scope is a reasonable starting point for a quote. Class booking pulls in the availability and reminder work covered in our booking app cost guide, so a gym that only needs a card and announcements can start smaller. For the full list of membership cost drivers, see what a membership app should cost and include.
Getting your membership app scoped
Write down what members pay for today, how they pay, and the three things you want them to do in the app every week. That is enough for discovery to produce a screen list and a payment plan. The membership app page shows how we approach version one, and you can request a written scope and quote when you are ready.
Frequently asked questions
How much does a fitness member app cost to build?
It depends on content structure, class booking, challenges and the payment route. DFY Games quotes each app from a written scope rather than a fixed price.
Does a gym app have to use Apple or Google in-app purchase?
Generally not for physical gym access, which both stores treat as a service used outside the app. Digital workout subscriptions sold in the app generally do. Check the current rules for your markets.
Should my first fitness app connect to wearables?
Usually not. Wearable and health data integrations add permissions, privacy disclosures and store review attention, and the app can run challenges on workouts and check-ins it already records.
Can a fitness creator app include challenges?
Yes. Streaks, program completion and leaderboards based on workouts completed in the app are a small addition to a content app.
Can I make health claims in my app's store listing?
Avoid them. Describe what the program contains, and have a lawyer check any wording that promises results.
