Your ultimate companion to forge strength, track progress, and shatter your fitness goals.
RepForge (formerly Workout-logger) is an open-source, beautifully designed workout logging mobile application built with Flutter. Whether you're a powerlifter, a casual gym-goer, or someone just starting their fitness journey, RepForge empowers you to track your workouts seamlessly, visualize your progress with detailed analytics, and stay motivated.
Tired of subscription-heavy fitness apps? RepForge is built by lifters, for lifters. It keeps your data local, offline, and completely under your control.
- 📊 Advanced Analytics: Volume trends, per-exercise progression with estimated 1RM, muscle-group focus and recovery balance, and a full personal-records log — powered by
fl_chart. - ⚡ Super-Fast Logging: An intuitive active-workout flow with AI-suggested weight/reps for your next set, dropsets, and rest timers that gets out of your way so you can focus on the pump.
- 🗓️ Routines & Programs: Build reusable routines, queue up your next session, and follow structured multi-week training programs.
- 🫀 Health Connect Integration: Syncs workouts to Android Health Connect and reads sleep/heart-rate data back in to score daily training readiness.
- 🤖 AI Coach: A conversational, tool-calling coach (powered by Gemini) that can query your own workout history, chart correlations, and explain your progress — see Anti-Features below.
- 📱 Offline-First: Your data is stored locally for fast, secure access anywhere, even without internet.
- 🔄 Export/Import: Never lose your data. Back up and restore your workout history at your convenience.
- 🎨 Custom Theming: A modern, soft-futurist interface with a consistent design system.
RepForge's core workout logging, routines, and analytics work fully offline. The AI Coach is optional and relies on Google's Gemini API over the network — it's the only feature that isn't free/local, and it's disclosed as such in the app's F-Droid listing.
