Log a set faster than pen and paper

Every set prefills from what you did last time — same weight, same reps. One inline tap confirms it; if today went differently, nudge the numbers and go. No forms, no friction between sets.

Your go-to workouts, one tap away

Start from a builtin template, or save a finished workout as a template of your own. Either way its exercises drop into a fresh session, prefilled from your history.

No signal? Keep lifting.

Stronger is offline-first: every set you log without signal is saved on your phone instantly, and syncs on its own when you’re back online. The basement gym is not a problem.

Am I getting stronger?

Every session lands in your history, and each exercise gets a top-set sparkline — your heaviest set over recent sessions, so the trend is visible at a glance.
