How Do You Add Subscriptions to an App Built With AI?
Describe your app and what is premium
Tell Fastshot what the app does and which features sit behind a subscription. Approve the plan and the first version appears in about 5 to 7 minutes as an iOS + Android project.
Open the Monetization page
It has a tab for each provider: Adapty and RevenueCat. Adapty is the default.
Connect Adapty or RevenueCat
For Adapty, save your public SDK key and placement ID. For RevenueCat, connect your RevenueCat account, then choose its project and app.
Ask the AI to add subscriptions or in-app purchases
Say what you sell: a monthly plan, a yearly plan, or a one-time purchase. Fastshot adds the purchase flow to the app. Refine it by chat like any other screen.
Test, then install
The browser preview and Expo Go mock purchases so you can walk through the flow. Build the app to your phone for live purchases, then publish to the App Store and Google Play.
RevenueCat or Adapty: Which Should You Connect?
Both manage subscriptions and in-app purchases across iPhone and Android, and Fastshot supports both. Pick RevenueCat if you already have a RevenueCat account or project: connect it once and choose the app. Pick Adapty, the default, if you want the shortest path: it needs only your public SDK key and placement ID.
Each provider has its own tab on the Monetization page, so you can switch the one your app uses. For more on each, see the lesson add subscriptions with Adapty or RevenueCat.
