Time your gym class

Set your workout and cooldown timings, then follow the current phase and round on one clear screen. Haptic and audible cues help you notice when a phase is approaching its end.

Workout timer with music controls

Keep Apple Music controls with the workout, so you can manage the session without repeatedly switching apps. Choose the music that suits your class.

Make yourself heard

Use Shhh to lower the music while you give instructions. Spend less time competing with the speakers and more time guiding the people in front of you.

Ready for your next routine

Use the routines screen to organise your sessions. Pause a workout when you need a moment, then pick it back up from the same screen.
