Interval timer

An interval timer alternates work and rest for a number of rounds. Here you describe the intervals in words instead of setting dials: 10 x 1 min on 30s off, 8 x 30/15, 4 x 4 min with 3 min rest between, 3 rounds of 40s plank, 20s rest. Numbers, units and rounds are read the way you would say them.

Add a warm-up and a cool-down as above, chain different blocks with commas, or use a named format — tabata, emom, amrap, boxing. The preview under the box lists every block with its length and the total; tap a value to edit it in the text. Beeps, a voice cue and a big display come with it; nothing to install.
