Timer Modes
Every format you need for CrossFit, functional fitness, and HIIT training.
Complete the workout as fast as possible. The timer counts up so you can chase your best time.
Every Minute On the Minute. Start a new set at the top of each minute. Rest whatever's left.
As Many Rounds As Possible in a set time window. Keep moving and beat your score.
High-intensity intervals with fixed work and rest periods, repeated for multiple rounds.
Build any interval sequence from scratch. Mix work and rest blocks in any order.
Count an athlete's reps in competition. Set a timecap and track every valid rep in real time.
Apple Watch
Install it once and leave your phone in the bag. The watch app runs on its own.
Every format on your wrist, and it keeps running with your wrist down — the clock doesn't stop mid-set.
Dial in the time and rounds with the Crown. A haptic on every round and interval, so you feel the change.
See your heart rate and calories while you work, and save the finished workout to Health.
Call a heat rep by rep: valid reps, no-reps, undo a miscall, and the result to read out at the end.
