WorkoutPhase

Five phases. One wrist.

Each state of a workout has its own purpose-built screen. The watch always shows you exactly the next thing you need to do.

Musklr active-set screen on Apple Watch — Dumbbell Bench Press, 23.9 kg, 8 reps, set 1 of 3
Phase · core

Two columns. kg left, reps right.

Same layout as your iPhone — kg on the left, reps on the right. Tap to swap focus, dial the crown to change the value. Two taps and the set's logged.

  • Numbers where your hand expects them — Same column order on every device. Muscle memory transfers.
  • Dial, tap, done — Crown sets the number, tap logs the set. That's the whole interaction.
Musklr rest timer on Apple Watch — 2:56 remaining, heart rate 135, up next: Dumbbell Bench Press
Phase · countdown

A timer that knows what's next.

A linear ring counts down your rest. Underneath, the next set is already lined up — so when you look at your wrist mid-rest, you're already prepped.

  • Glance and you know — How long you've got, what's coming, no tapping required.
  • Previous set in view — Last session's kg × reps shown next to the timer, so you know what to beat.
  • Haptic at 10s, then at zero — Set up. Then lift. Two taps your wrist learns to recognise.

Fewer taps. More lift.

Musklr timed exercise on Apple Watch — 45 Degrees Back Extension, 0:05 elapsed, heart rate 76
Phase · hold

Big elapsed. Big stop button.

Plank, farmer's carry, dead hang — anything you measure in seconds. The clock fills two thirds of the screen, the stop button owns the rest. You can read it shaking.

  • Counts up by default — Or set a target and it counts down — automatic by exercise type.
  • Stop owns the bottom third — Big enough to hit with sweaty fingers, far from accidental taps.
  • HR overlay — Live heart rate next to the timer — see when intensity drops.
  • Auto-saves on stop — No confirmation dialog. The set is logged, you move on.
Musklr personal record on Apple Watch — Dumbbell Bench Press, 35 kg, with confetti
Phase · the moment

When you go heavier than ever before.

Full-screen takeover. The new number, your previous best, and a haptic double-buzz played twice. Tap to dismiss, or wait — it clears itself.

  • Dopamine you actually earned — No streaks, no badges, no XP. The reward is heavier than last time — and the kilos are real.
  • Felt before it's read — Double-buzz on your wrist the second the rep counts. Your wrist learns the pattern.
  • Phone celebrates at the same moment — Same second on iOS. No delay, no missed PR.
Musklr workout complete on Apple Watch — Great work, SATS Squat, flat bench and triceps session, with time and kg totals
Phase · summary

Four numbers, then back to life.

Time, volume, sets, PRs. Save in one tap and the workout is on your phone and in Apple Health. Closing the gym door takes longer.

  • The headline, then your day — Debrief on the phone later. The watch tells you what mattered.
  • Saves to Apple Health automatically — Workout type, energy, heart rate — your activity rings update themselves.

The lifting app for your wrist.
