Everything the gym needs

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.

Yours, on your device

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

How it works

Open. Lift. Done.

  • Pick a routine. Grab a template or build your own split in a couple of taps.
  • Start the session. Your sets are pre-filled — confirm with a tap, adjust with the dial.
  • Rest auto-starts. Swap an exercise if a machine's taken, add one on the fly.
  • Finish & track. Volume, PRs and calories logged — your strength curve updates instantly.
