Interval Timer keeps you honest, counting every work and rest period so you get the full benefit of every session.

Set your session once, hit start, and let clear audio cues tell you exactly when to explode into work and when to recover — no glancing at a watch, no losing count, no broken rhythm. BUILD THE SESSION YOU WANT Quick Tabata blast or a long circuit, equal work and rest or lopsided intervals, two rounds or twenty — it's all yours to shape. Dial in your preparation time so you're ready before the first round, save the routines you love, and launch them in a single tap next time. MORE THAN A GYM TOOL Interval training isn't just for athletes. Use timed intervals to make housework fly by, to structure focused study or deep-work sprints, or to add rhythm to stretching and breathing exercises. Anywhere a little structure helps, Interval Timer is ready.
