Agent Arnold
AI-powered gym tracker with real-time coaching and workout planning
Visit agent-arnold.app ↗What is Agent Arnold?
Agent Arnold is a fitness tracking app that combines workout logging with an AI coach powered by Claude. Users can record lifts, ask for form corrections and exercise modifications, and generate personalized routines. The app includes progressive overload tracking, an anonymous global leaderboard, and full data export.
Built as a React PWA that works offline, the app was entirely created using Claude Code. The maker, a daily user themselves, emphasizes catching bugs in real time and building features based on actual gym needs rather than startup assumptions.
