## What is MSCLS?

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
- The watch shows elapsed time, current exercise, set progress and heart rate on one screen
- A heart-rate chart with average and peak BPM after each session

APPLE HEALTH AND STRAVA
- Save finished workouts to Apple Health as strength training sessions
- Connect with Strava and upload a workout as a strength activity with muscle heat map, heart-rate chart and per-exercise breakdown
- Share a workout as an image card or as a .fit file

200+ EXERCISES
- A built-in library of strength and cardio exercises - search by name, muscle or equipment
- Add your own exercises or adjust the built-in ones

HISTORY AND BODY WEIGHT
- Every past workout with volume, sets and PR badges
- Weekly stats: workouts, volume, top muscle, PRs, peak heart rate and training streak
- Track your body weight over time

PRIVATE BY DESIGN
- No account, no login
- Your workout data is stored on your iPhone, not on our servers
- Nothing goes to Apple Health, Strava or Garmin Connect unless you switch it on
- Anonymous usage statistics show us how the app is used; you can turn them off in Settings

THE FULL VERSION ADDS
- Rest timer between sets: starts when you tick off a set, shows on the Lock Screen and your watch, and taps your wrist when the rest is over
- Progress charts: weight and volume trends for strength exercises, time and distance trends for cardio
- Garmin: live heart rate from your Garmin watch, your next set on your wrist, and the workout recorded to Garmin Connect as a native strength activity with heart rate
- Personal records broken down per gym
- Unlimited routines, gyms and custom exercises
