LiftLegacy is a mobile fitness tracking app MVP built with React Native, Expo, TypeScript, and Supabase. The app is designed for gym-goers who train regularly but do not properly track their progress. Many people go to the gym for months or years but still do not have a clear record of their workouts, personal records, strength progress, body measurements, weight changes, or progress photos. LiftLegacy gives users one place to log workouts, follow weekly training plans, track personal records, view strength progress through graphs, record body measurements, upload progress photos, and build streaks, XP, badges, and Gym Passport achievements. This is a source-code MVP/template. It is suitable for developers, fitness coaches, gym owners, startups, or buyers who want a ready fitness app foundation that can be customized, connected to their own Supabase project, monetized, and published under their own brand. Tech stack:React Native, Expo, TypeScript, Expo Router, Supabase Auth, PostgreSQL, Supabase Storage, and TanStack Query. Important:This is source code only. It does not include active users, revenue, App Store account, Google Play account, Stripe account, or Supabase account. The buyer will need to create their own Supabase project and configure the provided setup SQL.
