KasMaker: Muscle Tracker

See every muscle you train. Your body map lights up rep by rep, PRs detect themselvaes, and KasMaker reveals the muscles you keep skipping. No ads, ever.

KasMaker is a muscle tracker, not just a gym logger. Log your sets and watch an interactive body map light up — primary and secondary muscles, so you see exactly what you've trained.

Log your sets, and KasMaker does the thinking: it catches every personal record, tracks your push/pull balance, watches your recovery, and shows you what to train next.

TRACK EVERY MUSCLE Your body map fills in as you log. See at a glance which muscles are worked, which are fresh, and which you keep skipping. Tap any muscle to dig into its training history and top exercises filtered by your equipment.

LOG WORKOUTS YOUR WAY Pick from 800+ exercises with instructions and images. Repeat a past workout in one tap, start from a saved routine, or build from scratch. Step away and come back — your session picks up right where you left off.

AUTOMATIC PR DETECTION Personal records are caught the moment you log them. The first set at a new weight gets highlighted, so a milestone never slips by.

REST TIMER Built-in rest timer that auto-starts when you finish a set and stays out of your way between exercises. Adjust the duration to fit how you train.

HOME SCREEN WIDGETS Your muscle map, right on your home screen. See what's fresh and what's still recovering without opening the app. Small and medium sizes.

LIVE ACTIVITY & DYNAMIC ISLAND Run your whole workout from the Lock Screen and Dynamic Island — timer, current exercise, set progress. Complete sets and save your workout without unlocking your phone.

BUILT FOR PRIVACY Your data lives on your device. iCloud sync is optional, and no account is required. No analytics. No tracking. No ads. Ever.
