Set & Burn: Interval Timer

Set your work and rest, then follow signal sounds and voice cues through every round and set.

Three switches in the editor shape each workout: Rest, Sets and Count jumps. With Count jumps on, your iPhone or motion-sensing AirPods count jump rope jumps and running steps, and with End by set to Count, a round ends when you reach the count you set. Time spent in Work intervals adds up in Lifetime work time.
