Prompt template
Water tracker prompt — copy, paste, build
A prompt for a small, polished native water tracker — daily goal, quick-add buttons, weekly chart, and configurable reminders. Designed as a one-screen-plus-settings app that feels great after the first build.
The prompt
Build a native iOS and Android water tracker with: (1) a single home screen showing a large animated water glass filling toward a daily goal, (2) quick-add buttons for 100ml, 250ml, 500ml, and a custom amount, (3) a weekly chart at the bottom showing the last 7 days of intake vs goal, (4) a settings screen with daily goal, units (ml or oz), and reminder cadence (every 1, 2, or 3 hours during waking hours). Use Expo, React Navigation, twrnc for styling, AsyncStorage for daily logs, and Expo Notifications for reminders. Tone: bright, playful, single accent color (blue).

Why this prompt works in AppGenie
Tiny apps live or die on motion. The animated water-glass fill needs to feel responsive on the cheapest Android device. AppGenie's validator catches the common Reanimated / Snack incompatibilities that would normally bounce the build.

Open prompt →Water tracker prompt — FAQ
Does the animation work in Snack live preview?
Yes. AppGenie autofills react-native-reanimated as a peer dependency and the validator confirms the import path is Snack-compatible.
Can I switch between metric and imperial after launch?
Yes. The settings screen exposes a units toggle out of the box and the data layer stores intake in milliliters internally for clean conversion.
