Zero Taps to Log.
Your current set is always front and center. Weight and reps are pre-filled from your template targets. If they match, just hit Complete Set — zero adjustments needed.
Twist to Adjust.
Tap the weight or reps box to select it, then twist the Digital Crown to adjust. A green outline shows which value you're changing. Weight moves in 2.5 kg increments, reps in 1.
Live Heart Rate & Calories.
Real-time BPM streamed from Apple Watch sensors and shown alongside your progress. When you finish a set, average, max, and min heart rate are logged automatically with your set data. Active calories burned are tracked in real time via HealthKit and saved to your workout summary.
Rest. Then Go Again.
After completing a set, a rest timer appears automatically with a circular countdown ring. Skip it or wait — when time's up, the view auto-advances to your next set with a haptic tap.
