Plan it. Lift it.
Watch it climb.
kach is a no-nonsense gym tracker. Build any routine, log every set in seconds, and see your strength trend over time — clean, fast, and yours.
Built for the way you actually train
Not a spreadsheet. Not a social network. Just a fast, focused tool for getting stronger.
Build any routine
Start from a proven template or create your own split. Name your days, set weight, reps and rest — your way.
Log every set, fast
Pre-filled from your plan — tap to confirm. Supersets, drop sets, warm-ups and AMRAP are all first-class.
Watch strength climb
Per-exercise history, est. 1RM trends, PRs and weekly volume — see progress instead of guessing at it.
Plate math, solved
Tap the weight and kach shows exactly which plates to load — for any bar, with the plates you actually own.
On your wrist
The Apple Watch companion shows the current set, rest timer and live heart rate — log without your phone.

No sign-up, no cloud lock-in. Your training lives on your phone and syncs with Apple Health.
