Typical costs
1 credit = 10,000 tokens the AI reads or 1,000 tokens it writes. Small, specific requests are cheap; regenerating everything is not. Ranges below are what we see in practice.
| Action | Credits |
|---|---|
| Generate a 4-tab app from a paragraph | 8 – 20 credits |
| Add a screen | 3 – 8 credits |
| One specific change to one screen | 1 – 3 credits |
| Add a native feature (reminders, camera, scan) | 2 – 6 credits |
| Change colours or copy across the app | 2 – 5 credits |
| Preview, hand-edit text or data, export | Free |
A first app — generate, ten changes, a native feature, export — typically lands between 30 and 70 credits.
Pricing questions
What is a credit?
A unit of AI work. Credits are deducted by tokens processed: 10,000 input tokens (what the AI reads — your prompt, the relevant files) cost 1 credit and 1,000 output tokens (what it writes) cost 1 credit. A short, targeted request is a few credits; regenerating a whole app is many.
Do credits expire?
Purchased credits do not expire. The free 100 are yours to use whenever.
Is there a subscription?
No. You buy a credit pack when you need one. Nothing renews, nothing is charged while you are just looking.
What is free forever?
Opening projects, tapping through previews, editing text and data files yourself, and exporting the Android Studio project — as many times as you like.
How are packs priced?
Packs are sold through Google Play billing inside the app, in your local currency; the current prices are shown on the credits screen. Larger packs cost less per credit.
Can I get a refund?
Google Play's refund policy applies to credit purchases. Unused credits from a refunded pack are removed. If something went wrong with a purchase, contact us and we will sort it out.
