Musku - Workout Tracker
Track Sets, Reps & Records
Only for iPhone
Free · In‑App Purchases
iPhone
Track every set, every rep, every record. Create or pick a program. Chat with your favorite AI about your performance in one tap. Precise, efficient, no fluff.
Musku, your strength training journal.
A workout tracker built for the gym: fast, clear, no ads, no social feed. You log, you progress, that's it.
Logging a session has never been easier
Build your own session templates or pick from ready-made programs. Hit start, run through your sets, and the app pre-fills your weights from your last workout. All that's left is to confirm.
iOS widget on your home screen
Launch your workouts in one tap, without even opening the app. Medium (4 workouts) or large (8 workouts) size, fully configurable via long-press on the widget.
AI analysis of your progress
Send a summary of your last 15, 30 or 60 workouts straight to ChatGPT, Claude, Gemini or any assistant. You get personalised feedback on your weak points, your progress and the adjustments to make. 100% local, nothing leaves your device until you decide.
Track real progress
Personal records (max weight, estimated 1RM, volume), heatmap of your sessions, muscle distribution, top progressions, monthly summary, badges and achievements. Everything is computed automatically, from what you already do.
Offline by default
No Wi-Fi at the gym? No problem. You can start, edit and finish a session without a connection. Everything syncs as soon as you're back online.
Apple Health integration
Your strength workouts flow automatically into Apple Health, including duration and estimated calories.
Live Activity and rest timer
Keep an eye on your rest from the lock screen or Dynamic Island. The timer adapts to your exercise.
A quiet coach
A daily banner on your dashboard reminds you what deserves attention: a neglected muscle group, an inactive stretch, or a useful tip. Dismissable in one tap.
Privacy first
No feed, no social sharing, no ad tracking. Your data stays yours.
Premium (optional)
Beyond 3 session templates and basic stats, go Premium to unlock unlimited templates and the full set of advanced statistics. No commitment, cancel anytime.
