Bring every timer into one routine. My Set Timer lets you run a sequence of timers in the order you choose. Customize names, durations, and order to create routines for studying, exercising, meditating, and more. BUILD YOUR OWN ROUTINES Put preparation, activity, breaks, and cooldowns into one sequence. Save multiple routines so your favorite flows are ready when you are. ADD LEFT/RIGHT PAIRS AND BREAKS Quickly add paired timers for stretches on both sides. Automatically insert a break after each activity, and choose whether to include breaks and how long they last. SEE WHAT’S NEXT Follow your routine with a large countdown, a circular progress ring, and a timeline. Interval sounds and countdown sounds during the final five seconds help you keep track without watching the screen. USE APPLE WATCH Sync routines and settings from iPhone to Apple Watch. Run a session on your Watch independently, with controls to start, pause, resume, and move between steps. While connected, iPhone and Watch share your session’s progress and controls. TRY INTERVAL WALKING Start with a preset that alternates three minutes of brisk walking and three minutes of easy walking for five rounds—a 30-minute routine. Adjust durations, rounds, and optional warm-up and cooldown periods. LOOK BACK AT YOUR PROGRESS Completed sessions are saved in the app. Review your time in the calendar and charts, and see your consistency over time. If you leave a session unfinished, resume from your saved progress. MAKE IT YOURS Choose a color, light or dark tone, and icon for each routine. Set the app’s overall appearance to follow your system or stay light or dark. No ads are shown during sessions. Instant control between iPhone and Apple Watch requires a connection between the devices.
