Tetrad is the workout tracker that gets out of your way. Build your split, log every set in two taps, and watch your strength compound — one beautifully dark screen at a time.
No social feed. No streak-shaming. Just the tools that make you stronger, designed to disappear while you lift.
Push/Pull/Legs, Upper/Lower, Arnold, or your own. Create programs and splits in seconds and pick your day with one tap.
A purpose-built numpad, smart weight increments, and a rest timer that starts itself. Logging gets out of your way.
Estimated 1RM, volume, and per-exercise trends rendered with buttery Skia charts. Watch the curve go up.
Log weight, set a goal, and follow the trend line toward it — in pounds or kilograms, whichever you think in.
A private, on-device gallery with side-by-side compare. See the change the scale can't.
Reads your steps, writes completed workouts and body weight back to Health. Your data stays on your device.

Absolutely. Choose pounds or kilograms in Profile and every screen — logging, goals, and charts — follows your preference.
