PROJECTAI-Powered Personalized Coaching App
RATIONALESupabase gives you auth, database, and realtime out of the box — drastically cutting backend setup time for a solo/no-team scenario. React Native with Expo lets a single developer ship to both iOS and Android without native expertise. OpenAI API is the fastest path to a credible AI coach without training custom models, which is critical for a seed-stage budget.

⚠ RISK FLAGS
!No team + ASAP timeline is a critical conflict — this app requires at minimum 1 full-stack developer and 1 UI/UX designer; rushing without them will produce an unshippable product
!Seed budget may be tight if outsourcing to an agency; consider hiring a solo freelance full-stack developer to stretch runway
!AI coaching domain is vague — without defining the specific niche (fitness, career, mental wellness), the GPT-4o prompt engineering and onboarding flow cannot be properly scoped or differentiated
!OpenAI API costs can spike unpredictably at scale — even at micro scale, long coaching sessions consume significant tokens; rate limiting and session caps must be built into MVP
!App Store approval for AI health/wellness coaching apps can be delayed or rejected without proper disclaimers; legal/compliance review needed before submission
!Session memory and data retention of personal coaching conversations creates GDPR/data privacy obligations even for early users — needs privacy policy and data handling strategy from day one
