Store description excerpt
Simple Muscle is an AI-native workout tracker built for the moments between sets—now on iPhone and Apple Watch—and for the AI chat you already use. Plan a workout once, then log each set quickly with clear controls for reps, weight, or time. Move between exercises, add extra sets, and manage recovery with a rest timer that follows your workout to the Lock Screen and Dynamic Island. Take your saved workouts to Apple Watch and train without carrying your phone. Follow your workout exercise by exercise, adjust weight, reps or duration, complete sets, and manage rest periods directly from your wrist. The core tracker is free and works offline. Create workouts, explore a library of more than 400 exercises, review session history, check weekly volume, view progress charts, adjust kg/lb and rest settings, and complete workouts without an account. Optionally save completed workouts to Apple Health so they appear in your activity history. If you sign in, optional sync can back up and restore your training data across devices. With the optional AI Connection subscription, Simple Muscle can connect to ChatGPT, Claude, or other MCP-compatible assistants so an assistant you authorize can plan, edit, and analyze workouts using your training history.
