MSCLS: Gym & Workout Tracker

MSCLS is a gym and workout tracker built for strength training. Log every set in seconds, see the muscles you trained on a heat map, and catch each personal record as it happens. Free to download, no account, and your workouts stay on your iPhone.

LOG EVERY SET, FAST
- Type weight and reps, then tap the circle to tick off the set
- Sets come prefilled from your last session at the same gym
- Mark a set as warm-up, drop set or failure
- Log gym cardio too - treadmill, rowing, cycling - with time and distance

YOUR NEXT SET, WITHOUT UNLOCKING
- The Live Activity on the Lock Screen and Dynamic Island shows the weight and reps of your next set
- Tick it off right there, or from your Apple Watch

MUSCLE HEAT MAP
- An anatomical muscle map (male or female figure) shades each muscle by how hard you trained it
- The weekly heat map shows what you hit and what you skipped - swipe back through recent weeks
- A muscle map on every workout summary, every past workout and every exercise
- Choose your own heat map color

PERSONAL RECORDS
- Live PR detection: beat a best and the set earns a trophy badge right away
- Records for heaviest weight, best set volume, longest cardio time and farthest distance

ROUTINES FOR YOUR SPLIT
- Build workout routines such as Push, Pull and Legs from the exercise library
- Every routine starts prefilled with the numbers you used last time
- "Up next" shows which routine comes next in your split
- Reorder, add or swap exercises in the middle of a workout

HEART RATE FROM APPLE WATCH
- Start a workout on your iPhone and your Apple Watch starts streaming live heart rate
