IntervalGuide: Intervall Timer

Your workout. Your rules. IntervalGuide is a fully customizable interval timer for
HIIT, Tabata, boxing, and circuit training - built to work exactly the way you train.

Design your interval workout block by block: set work and rest periods, add rounds,
choose audio cues, and train in the right heart rate zone. Shake your iPhone to pause
or resume - no need to touch the screen mid-round. Whether you're doing HIIT, boxing
rounds, kettlebells, running intervals, or strength-training rest periods,
IntervalGuide adapts to your routine, not the other way around.
