Subscriptions
A subscription app is a product plus a small billing system: plans, access rules, renewals, cancellations and a paywall that has to appear at the right moment. Five decisions made before design decide most of the scope, the timeline and how easily the offer can change after launch.
Subscription app development means building the product and the machinery around it: plans and billing periods, what each plan unlocks, renewals and cancellations, restoring access on a new device, and a paywall. Before design, decide five things: what you sell and therefore where the payment can happen, how plans are structured, where the paywall appears, who can change the offer after launch, and how one member keeps one subscription across every sign in method. Those answers drive more of the scope than the screens do.
Key takeaways for founders planning a subscription app
From the outside a subscription app looks like any other app with a price screen. Inside, it carries a set of rules the business depends on: which plan a member has, what that plan unlocks, when it renews, what happens after a failed payment or a cancellation, and how access comes back when someone reinstalls the app or switches phones.
Each of those rules needs a place in the data model and a screen or a message for the member. That is why two apps with the same number of screens can differ a lot in scope. The difference sits in the subscription logic, and it is cheapest to settle before design starts.
Apple and Google treat digital content and real world services differently. A subscription to workouts, lessons or premium features used inside the app generally has to go through in app purchase. Access to something that happens in the physical world, such as classes in a studio, can usually be sold through your own checkout. Many products mix both, and the mix decides the payment flow.
Our guide to in app purchase fees explains where the line runs and what each store takes. On Android the model changed in 2026, with a service fee separated from a billing fee that alternative billing can avoid, as explained in Google Play fees.
What it changesPayment provider, store review questions, your margin per member.Number of tiers, billing periods, discounts for longer commitments, free trials or introductory offers, and upgrades between plans. Each option is simple on its own. Together they define every state a member can be in, and every state needs to be handled in the app and in support.
What it changesData model, paywall layout, renewal and upgrade logic.A paywall on the first screen asks for money before the app has shown anything. A paywall at the moment of intent, when the member tries to do the thing the subscription unlocks, explains its own value. In a booking app, that moment is usually the first attempt to book.
What it changesOnboarding flow, free experience before payment, how conversion is measured.If plans, prices and promotions are written into the app, every change is a new release and a store review. If they are loaded from the backend, the team can launch an offer the same day.
What it changesBackend scope in version one, speed of every future campaign.Sign in with Apple, Google sign in and phone number login make joining easier, but each one can create a separate account for the same person. The subscription then sits on one account while the member signs in with another. In Body Vibes we built account merging across all three methods, and since release there have been no duplicate accounts.
What it changesAuthentication logic, support load, trust in the product.The subscription logic, not the number of screens, is what makes two similar looking apps cost very different amounts to build.

Body Vibes sells access to classes in over a hundred partner studios under one subscription.
Apps Value worked on the part of the app that turns a new user into a member: the onboarding path, sign in with Apple, Google and phone number, and the subscription paywall, delivered in about a month inside the existing Flutter app. The details are in the Body Vibes case study.
Evesport, which we built from scratch, uses a different model. Trainers use the app for free, and clients choose between a Basic plan for training with one trainer and a Premium plan that gives access to up to five trainers across longer terms.
Charging the side with more willingness to pay, and keeping the supply side free, was settled in kickoff before any code was written. The Evesport case study covers how that decision shaped the product.
What should not wait: the plan structure, the paywall placement, restoring access on a new device and one account per member. These are expensive to change once paying members depend on them.
The delays we see on subscription and booking products are rarely in the code. App Review regularly asks how the business model works and whether payments should go through in app purchase. It is a predictable step, resolved by explaining the model clearly, and it is worth preparing for rather than discovering at submission.
The other common cause is the developer account. An Apple developer account opened late or left unconfigured holds up testing and release, and setting it up is not a one day task. Opening store accounts in the week of kickoff removes one of the most frequent reasons a launch date moves. Our article on the mobile app development timeline shows where these weeks sit in a real project.
About the source
It depends on the product itself and on the subscription logic around it: the number of plans and billing periods, whether offers are managed from the backend, the payment paths and the sign in methods. Our pricing page explains how we scope and price fixed price projects.
For digital content and features used inside the app, generally yes. For real world services, such as access to classes or sessions held in person, the app can usually use its own checkout. Products that mix both need both paths.
Both stores take a commission on subscriptions sold through in app purchase, and the rate drops after a member's first year and for smaller developers. Since June 2026 Google also splits its fee into a service fee and a billing fee, so the billing part can be avoided with alternative billing. The current numbers are in Google Play fees and in app purchase fees.
Usually not. A paywall shown when the member tries to use what the subscription unlocks explains its own value. In a booking app, that is usually the first attempt to book.
Yes, if the paywall loads plans, prices and promotions from the backend instead of having them written into the app. Offers can then change the same day, without a new release and a store review.
Yes. On Body Vibes we added a new onboarding, sign in and paywall inside the client's existing Flutter app as a regular release. Our mobile app maintenance services cover this kind of ongoing product work.
Both handle subscriptions well on iOS and Android from one codebase. Body Vibes and Evesport are Flutter apps. The choice usually depends on the team that will maintain the app after launch.
Whether you are starting from scratch or adding subscriptions to an app that is already live, we will scope it with you and give you one fixed price.
