How the app works
Minutes
Sized to the window you have
Sets, rests and transitions are built to fit the minutes you give us. Your pace owns the clock.
Rebuilt
A day that slips moves forward
Miss Monday and the week is rebuilt, not abandoned. A month away brings you back on a ladder.

Rules, not a black box
Seven rules drive every load. Each is graded against the evidence and published, with what we don't claim.
Check-in
Tonight eases when you do
Three taps against your own baseline. No calibration period, no wearable required, no score. Works with Apple Health if you allow it. Nothing from Health leaves your phone.
The session
One session, start to finish.
Preview it, play it, log it. Three screens, nothing else to manage.
The limits
What we don't claim
The category sells guarantees. We publish the limits instead.
The elapsed time. Sessions are built to fit your minutes at standard rests. Your pace owns the clock.
A readiness score. Three taps shape tonight against your own baseline. No calibration period, no number.
Injury prevention. The comfort sheet eases, swaps or stops a movement. Sharp or radiating means see a professional.
Body composition. We plan strength and conditioning minutes. Nothing here measures fat, weight or a "biological age".
An AI coach. The engine is rules and math: same inputs, same outputs. A language model only writes the words around a decision. It never picks a set, a rep, a load or a minute.
Medical advice. General-audience information — not medical advice. Sharp or radiating pain means see a professional.
Questions
Before you join
The six things people ask first. Anything else, write to us from the About page.
Yes. The first questions ask what you can do today, and the first weeks are built from that, not from a template. Loads start light and climb on your actual reps.

RPE, translated: what “listen to your body” actually means
“Listen to your body” is useless advice until someone hands you the dictionary. RPE is the dictionary: a 1-to-10 scale anchored to reps you can count.
