Tired of logging your workouts? Just tap. Train, tap a stamp — done in seconds.
No sets, no reps. Effortless workout tracking. No ads. Ever.
MuscleStamp is the dead-simple way to track your training. No weights to log, no sets to count, no rest timers to fuss over. Just tap a stamp for the muscle group you trained today—and you're done.
WHY MUSCLESTAMP
- One tap to log. Six color-coded stamps for chest, back, shoulders, arms, legs, and abs. That's the whole interface.
- Set goals at your own pace. Decide how many times a week you want to train each muscle group. No pressure, no rigid programs—just targets that fit your life.
- Watch your streak grow. Every workout fills in your calendar. Seeing the days stack up is the motivation that keeps you coming back.
- See all your progress. Total days trained, goal weeks hit, your best streak, and reps per muscle group—all your hard work, in one place.
- A built-in timer. Time your sessions right inside the app, no need to switch to another timer.
- Body-specific training programs (Pro). Dedicated menus for chest, arms, and abs. Just pick your training days, and today's menu shows up automatically—difficulty scales itself across 8 levels as you keep going.
Whether you're new to the gym or already grinding, MuscleStamp keeps tracking out of your way so you can focus on the work.
No accounts. No clutter. Just tap and go.
ABOUT THE PRO PLAN
The Pro plan is a monthly auto-renewing subscription. While subscribed, you get access to all published body-specific training programs (including any added in the future). After a 14-day free trial, it automatically converts to a paid subscription priced at $3.99/month (displayed price may vary by region—check the in-app purchase screen for details). Unless cancelled at least 24 hours before the end of the free trial or the current billing period, the subscription renews automatically and you will be charged. You can cancel anytime from your App Store account settings. Individual training programs are also available as one-time purchases.
