What it does

Built for the weight room,
ready for the track.

Session Tracking

Log every set with weight and reps, auto-filled from your previous session. Rest timer counts down between sets and skips itself on your last one.

HIIT & Intervals

Round-based interval timer with configurable work and rest phases. Log reps per round, monitor live HR, and see a round-by-round history as you go.

Heart Rate Monitoring

Pair a Bluetooth HR strap or FTMS fitness machine. Live BPM, session average, peak, and calorie estimate â€” on both phone and watch simultaneously.

Smart Pause

Pause mid-session â€” the clock stops. Auto-pauses after 15 minutes of no activity. Auto-finishes after 6 hours paused. Both thresholds are adjustable in settings.

Wear OS Companion

Full workout tracking on your wrist: weight and reps input, rest timer, HR display, pause mode. Finished sessions sync automatically to your phone.

Offline First

No account. No server. No subscription. Your complete workout history â€” exercises, templates, session logs â€” stays on your device and is always available offline.

Philosophy

Most fitness apps try to be everything â€” social platforms, coaching services, diet planners. GymTracker does one thing.

Log your sets. Time your rest. Carry your session on your wrist. No signup flow, no premium tier, no push notifications asking you to come back. Just a precise, fast tool that gets out of the way the moment you rack the bar.
