Fitness Tracker App

Log workouts, see real progress

A workout-logging starter in a charcoal dark theme. Today opens on a daily featured workout plus this-week streak, count, volume; a library browses workouts by category (Strength / Cardio / Yoga / HIIT). Starting one launches a session with set-by-set checkboxes, inline weight and reps editing, and a timer; Finish saves it with a recap. History is a 12-week heatmap with the session list; Profile has a streak ring, totals, and personal records. Runs on your own Supabase backend (Auth, RLS).

What you can do

A workout-logging app built with Expo / React Native and Supabase. The Today tab opens on a featured workout that rotates daily plus this-week stats; a library lets you browse workouts by category (Strength / Cardio / Yoga / HIIT). Starting one launches a live session with set-by-set checkboxes, inline weight and reps editing, and a running timer; finishing saves the session and shows a recap. History is a 12-week activity heatmap with the full session list, and a profile shows a streak ring, totals, and personal records. It runs on your own Supabase project, so you connect a backend and sign in before any of your data appears; the workout library itself is bundled app content, and you can tap 'Preview with sample data' to look around first.

Made forAnyone who wants a private workout tracker to log strength, cardio, yoga, and HIIT sessions and watch their progress build.

Connect
Backend gate shown until Supabase is configured; explains the two setup steps and offers a 'Preview with sample data' look-around.
Auth
Email and password sign-in / sign-up on your own Supabase project; sign-up captures a display name.
Today
Home tab: a featured workout that rotates daily, this-week stats (day streak, workout count, volume), and a few recent sessions.
Library
The bundled workout library with a category filter rail (All / Strength / Cardio / Yoga / HIIT); tap a card to start it.
Active workout
The live session: a running timer, each exercise's sets with inline weight/reps editing and a done checkbox, add-set, and Finish.
Summary
Post-workout 'Great job' recap of the just-saved session: duration, total reps, and total volume.
History
A 12-week activity heatmap plus the full list of past sessions.
Profile
An SVG streak ring toward a weekly goal, headline totals (workouts, best streak, total volume), a personal records card, and sign out.

Data model

customers
One row per signed-up user (mirrors auth.users) with email and display name; created automatically on signup, readable only by its owner.
sessions
One row per finished workout: category, date, duration, total reps, total volume, and a JSONB snapshot of the completed sets; owner-scoped.

Backend

Row Level Security on both tables: customers is read-only for its owner (id = auth.uid(), written only by the trigger, no client writes); sessions allows full CRUD scoped to the owner (owner_id = auth.uid() for both using and with check).
SECURITY DEFINER trigger function handle_new_customer, fired by the on_auth_user_created trigger after insert on auth.users, auto-creates the customers row (deriving a display name from metadata, the email local-part, or 'Athlete').
Realtime: public.sessions is added to the supabase_realtime publication and set to REPLICA IDENTITY FULL so DELETE payloads carry owner_id for the live per-owner subscription, syncing across the user's devices.
No additional SECURITY DEFINER RPCs, no storage buckets, and no Edge Functions - the schema is just the two tables, the signup trigger, RLS, and realtime. The workout library is bundled app content (src/lib/workouts.ts); only finished sessions are stored.
