RepLog

A gym workout session tracker. Log your sets fast, see your history, and watch your lifts progress over time.

Personal-use first, built multi-user and scalable from day one.

Stack

• Next.js (App Router) + TypeScript
• Tailwind CSS + shadcn/ui
• Supabase — Postgres, Auth, Row Level Security
• Recharts for progress charts
• PWA: installable, offline logging, sync on reconnect
• Hosting: Vercel (app) + Supabase cloud (data)

v1 scope

• Auth + per-user data isolation (RLS)
• Exercise library (~80 seeded + custom exercises)
• Fast session logging — weight, reps, RPE, warmup flag, "last time" inline
• Minimal templates — save a session as a template, start a session from one
• History — session list, session detail, per-exercise history
• Progress — estimated 1RM, auto PR detection, per-exercise trend charts
• Muscle heatmap — body diagram shaded by trailing-7-day volume
• Bodyweight log, rest timer, kg/lb setting, data export

Full detail and the data model live in docs/SPEC.md.
