About Musku - Workout Tracker
Musku, your strength-training log. A training tracker built for the gym: fast, clean, no ads, no social feed. You log, you progress. That's it. Logging a workout has never been easier Create your own workout templates or pick a ready-made program. Start it, run through your sets, and the app pre-fills your loads from last time. All you have to do is check them off. AI analysis of your progress and your program Generate a summary of your recent workouts (up to 100) or have your whole program reviewed, then paste it into the AI of your choice (ChatGPT, Claude, Gemini). The app pre-computes your key numbers (actual frequency, volume per muscle group, records) for reliable feedback: your progress, your weak points, what to adjust, and even an alternative program if yours falls short. Nothing is sent until you decide to. Real progress tracking Personal records (max weight, estimated 1RM, volume), workout heatmap, muscle distribution, top progressions, monthly summary, badges and achievements. Everything is calculated automatically, from what you already do. Apple Health built in Your strength workouts are logged automatically in Apple Health, including duration and estimated calories. Your weight and body measurements sync too, both ways for weight. Rest timer and Live Activity Keep an eye on your rest from the Lock Screen or the Dynamic Island. The timer adapts to each exercise. Body measurements Track how your physique evolves, not just your lifts. Log your weight, body fat and the size of your arms, chest, waist, thighs or calves in seconds. Every measurement has its own history and progress chart: visual proof that the work pays off, week after week. On your Apple Watch Track your workouts on your wrist, without pulling out your phone. Start a freestyle workout, search and add exercises, tweak your session on the fly, and get your recap at the end. A widget on your Home Screen Start a workout in one tap, without even opening the app. Medium (4 workouts) or large (8 workouts), fully configurable by long-pressing the widget. Premium (optional) Free for up to 3 workout templates and basic stats. Go Premium for unlimited templates, all advanced statistics and the AI program analysis. No commitment, cancel anytime.
