Prompt template
Fitness app prompt — copy, paste, build
A field-tested prompt for generating a native fitness app with AppGenie. Optimized for the multi-agent pipeline: structured screens, explicit data shapes, and a clear feature checklist so the A4 architect plans the project cleanly on the first run.
The prompt
Build a native iOS and Android fitness app with: (1) onboarding that asks goal, fitness level, and reminder time, (2) a home tab with today's workout card and a 7-day streak strip, (3) a workout detail screen with set-by-set timer, (4) a habits tab with check-in toggles for water, sleep, and supplements, (5) a progress tab with a weekly chart of workouts completed and streak length, (6) a paywall before unlocking advanced plans (Stripe-ready hooks), (7) push reminders configured per user. Use Expo, React Navigation, twrnc for styling, and AsyncStorage for offline-first state.

Why this prompt works in AppGenie
Fitness apps live or die on iteration speed — paywall copy, reminder timing, streak mechanics all need tuning. AppGenie's diff-aware pipeline patches one screen at a time without re-running the whole project, so you can A/B a paywall without breaking the workout flow.

Will the prompt produce a real native app or a web wrapper?
Real Expo + React Native. The output runs in Snack live preview today and is ready for EAS build when you take it to TestFlight or the Play Store.
Can I change the paywall copy after generation?
Yes. Open the project in the AppGenie builder and ask "rewrite the paywall headline to focus on annual savings." The diff-aware pipeline patches just the paywall, leaving the rest untouched.
Does the generated app store progress offline?
Yes. The prompt scaffolds AsyncStorage for streaks, habits, and workout completions, so users can log offline and the app syncs when connectivity returns.
Ready to ship a fitness app?
Paste this prompt into AppGenie. The diff-aware multi-agent pipeline produces a real Expo + React Native project you can preview live, iterate in chat, and own end-to-end.
