Klonk: Gym & Workout Tracker

Klonk is your strength training log for iPhone and Apple Watch. Set up your workouts once, then work through them set by set, on your wrist or on your iPhone.

IT REMEMBERS YOUR WEIGHTS What you managed in a set last time is already filled in next time. No copying from old notes, no digging through your history. Go heavier and the progress carries over to your next workout.

TRAIN WITH YOUR APPLE WATCH Start your workout right on your wrist and leave the iPhone in the locker. Set the weight with the Digital Crown, tick off the set, and the watch taps you when the rest is over. Heart rate and calories are tracked, and the workout is saved to Apple Health as strength training.

PLAN WORKOUTS THE WAY YOU TRAIN - Almost 200 exercises with instructions and a muscle map, plus your own - A set plan per exercise: straight sets, pyramids or every set on its own - Supersets: two exercises in alternation - Timed holds like the plank with a countdown - Filter exercises by muscle group

PROGRESS YOU CAN SEE - Charts per exercise: estimated one-rep max (1RM), heaviest set and volume - The muscle map shows what a workout works - After every workout: duration, sets, reps and total weight lifted at a glance

YOUR DATA STAYS WITH YOU No account, no ads, no tracking. Your workouts live on your devices and sync between iPhone and Apple Watch through your own iCloud. The developer sees none of it. Back up to a file any time.
