Build a subscription app without the surprise bill.
Describe your habit, learning or wellness app. It arrives with onboarding, a paywall and settings checked against App Store rules on every build — and you change text yourself for free, roll back for free, and never pay overages.
Start free with 100 credits — about one app. No card needed.
Your credits go into the app, not into repairs
Change it yourself, free
Double-click any text, or change colours and spacing in the inspector. No credits, no prompt.
Undo for free
Every change is a version. If the AI breaks something, restore the last good one at no cost.
No overage charges
When your credits run out, the AI stops and tells you. Your card is never charged extra.
Know the cost first
A new app uses about 60–90 credits and a chat edit 5–15. One credit is $0.05 of AI.
Built to sell, not just to demo
Every app is a subscription business from the first build: onboarding that asks a question, a paywall, the main app and settings. Real purchases run through RevenueCat, and the store listing copy and framed screenshots are written for you.

Questions
- What's a credit?
- One credit is $0.05 of AI usage, charged at what each step actually used. Planning and building a new app usually takes 60–90 credits; a chat edit 5–15. Editing text and styles yourself and restoring a version are free.
- Can I be charged more than my plan?
- No. When your credits run out, AI steps stop until you have more. There are no overage charges.
- Who submits my app to Apple?
- You do, from your own Apple developer account: Apple asks that apps made with app-generation services be submitted by the person whose app it is (guideline 4.2.6). App Builder makes the build and uploads it with your keys.
- Do I own the code?
- Yes. Download the Expo / React Native source or push it to GitHub whenever you like.
- Can I cancel any time?
- Yes, in Settings. Your plan runs to the end of the month you paid for.
