What it does

Log a set in seconds

Weight, reps and reps in reserve for every set, with last time's numbers shown as a hint. A rest timer that keeps counting if you lock your phone.

Works with no signal

Everything saves on your phone first and syncs when you are back online. Add it to your iPhone home screen and the workout screen opens offline.

See progress, with a forecast

Estimated one-rep max, weekly sets per muscle and personal records. The forecast shows a range, and tells you when there is not enough data to draw one.

Machines are not barbells

A catalog that separates free weights, machines, cables and bodyweight, so a leg press at your gym is tracked as that machine and compared with itself.

Insights you can check

Each week, Claude reads your own logs and writes a short note: what moved, what stalled, and what to try. Every suggestion links to the numbers and the research behind it, so you can disagree with it.
