Everything a session needs, and nothing else

Log fast, see the trend, and let the Watch and Apple Health do the rest.

Log a set in seconds

Tap reps and weight and move on. Lifting, cardio, rowing and bodyweight all live in the same log: no spreadsheet, no fiddling between sets.

Proof that it is working

Your heaviest set per session plotted over time, so a good month is something you can point at rather than something you feel.

Start it from your wrist

A full Watch app and a Live Activity on the Lock Screen: your phone can stay in the bag.

Ask your own history

The chat can see every session you have logged, so the answers are about you.

Biological age

VO₂ max, resting heart rate, HRV, sleep and daily movement, resolved into one number that actually moves.

It lands where you already look

Workouts write straight to Apple Health, and the home tab is yours to arrange: fifteen widgets for streaks, PRs, volume and the rest.
