App Features

01 / Fast Logging

Three taps to a working set.

The quick-adjust row trades typing for tapping. Weight, reps, done — the keyboard never appears. Logging engineered to disappear so you can keep training.

02 / Personal Records

PRs the app finds for you.

Every set is checked against your history. New records surface automatically with a quiet badge — no chasing leaderboards, no shouting confetti.

03 / Muscle Coverage

See the gaps in your week.

A split-aware coverage engine maps each set to the muscle regions it actually trains — upper chest, posterior delts, long-head triceps. Imbalances stop hiding.

04 / Progression Trends

The line that pays off.

Per-exercise dual-axis charts plot weight against volume across weeks and months. Less guessing what to do next. More evidence that the work is working.

05 / Local-First

Your data stays yours.

The app runs entirely on-device by default. Optional iCloud sync via Sign in with Apple — no servers we own, no analytics on your sets, no tracking ever.

06 / Health Integration

Fits the rest of your stack.

Optional writes to Apple Health. Live Activity on the lock screen and Dynamic Island during workouts. Quiet integration, never noisy.

“Logging a set is so fast it disappears.” — Design philosophy, internal

DesignKit — the system underneath.

Tokens, themeable components, and a 34-preset catalog. Built once, shared across the ecosystem.
