Loop turns every session on your treadmill into a real workout on Apple Watch and in Fitness. Connect your treadmill over Bluetooth, start walking or running, and Loop combines what each device measures best: the treadmill provides distance, speed and steps, and Apple Watch provides heart rate and calories. When you finish, the workout is saved to Health and shows up in Fitness, so your rings, trends and history match what you actually did. EVEN IF YOUR ARM STAYS STILL Walking with your hands on the handrail, on a laptop or holding a coffee? On its own, the watch would count too few steps and too little distance. Loop uses the treadmill's data, so the workout is right even when your wrist is still. AS SIMPLE AS AN APPLE WORKOUT • The same pages, colours and gestures as the Workout app: time, heart rate, zones, calories, distance, pace and splits. • Change the treadmill speed with the Digital Crown, with the buttons or by sliding the speed indicator. • Start the belt from its remote and the workout starts on its own. Stop it and the workout pauses and ends by itself. • Pause, resume or end from your wrist and the treadmill follows. WALK OR RUN? LOOP KNOWS When you finish, Loop looks at your speed and cadence and saves the workout as a walk or a run. If it gets it wrong, change it with one tap and it's corrected in Health too. ON IPHONE TOO • Follow your watch workout live, including on the Lock Screen and in the Dynamic Island. • Change the treadmill speed from your iPhone. • History with Fitness-style summaries: splits, heart rate and zones, pace, cadence and effort. FREE TRIAL Try Loop free for 4 days. Then unlock it with a one-time purchase: no subscription, yours forever on iPhone and Apple Watch.
