All Musku features
A complete training log built for the gym: quick to use during your workouts and precise for tracking your progress over time.

During a workout
Log your sets without breaking your flow
Your last performance in plain sight
Every set shows what you did last time, without digging through your history. You compare against all your workouts or only the same template.
In detail →Automatic rest timer
Check off a set and the timer starts automatically. Set your rest time per exercise, from 30 seconds to 10 minutes: Musku remembers it in your template.
In detail →Notified even when your screen is locked
Musku alerts you with a vibration and a notification when your rest is over. On iPhone, the timer stays visible on the lock screen and in the Dynamic Island.
In detail →Warm-up, failure, drop sets
One tap on the pill marks a set as warm-up, failure or drop set. Warm-up sets are counted separately and don't add to your training volume.
In detail →Stopwatch for holds and cardio
For planks, isometric exercises and cardio, start a full-screen stopwatch: the duration is added to your set automatically.
In detail →Columns that fit each exercise
Musku adapts what you enter to the exercise: load and reps, bodyweight, added weight, assistance, distance, duration or hold time.
