The problem
Most fitness apps force manual logging or lock core features behind a signup wall. Zorvale lets people try the full experience as a guest — and log a meal just by taking a photo.

Personalized workout programs, live session tracking, AI-powered food logging, and progress insights — wrapped in an app that survives bad networks and interrupted sessions.
Architecture
How it's built
Production decisions across auth, AI, resilience, and release — shipped end to end.
5production layers
- Auth & data
- AI food logging
- Resilience
- Polish
- Release
Auth & data
Firebase (Google + anonymous guest) → Supabase third-party JWT, Postgres with RLS, and a guest-to-account merge so trial data never gets lost or duplicated on sign-in
AI food logging
camera/text input → server-side estimate via Supabase Edge Functions → user review → diary — no API keys exposed client-side, no photo gallery stored
Resilience
offline-tolerant caching (TanStack Query + MMKV), session recovery if the app is killed mid-workout
Polish
home-screen widget, light/dark theme, regional ad consent, Sentry crash monitoring in production
Release
versioned EAS builds, CI (lint/typecheck), Play signing, public privacy policy
