IntervalFlow: HIIT Timer

No ads, not even between rounds. Tabata, HIIT, EMOM, boxing — one tap to start, and the countdown stays on your Lock Screen.

A HIIT and interval timer that stays out of your way. No ads. No tracking. Nothing interrupts your workout.

WHY INTERVALFLOW

• No ads, ever — not a banner, not a video, not between rounds. Your countdown is never covered and your audio is never cut. • No tracking — no analytics, no advertising identifier, no account. Your workouts stay on your device. • Live Activity and Dynamic Island — the current phase, the countdown, and the round stay on your Lock Screen. Check mid-set without unlocking.

BUILT FOR REAL WORKOUTS

• Ready-made presets: Tabata, HIIT 40/20, EMOM, boxing rounds, and multi-set circuits. • Custom builder: prepare, work, rest, rounds, sets, rest between sets, and cooldown — to the second. • A countdown you can read across the room, with each phase in its own colour: work, rest, get ready, cooldown. • Sound, haptics, and voice cues, so you can keep your eyes off the screen and on the set.

IT KEEPS THE RECORD

• Every finished session is logged on its own — time, rounds, and an estimate of calories. • A daily streak and a weekly count, for the weeks when motivation needs a number.

Made for HIIT, Tabata, cross-training, boxing, running intervals, stretching, EMOM, and circuits — at the gym or on your living room floor.

Open it, tap a preset, and start. That is the whole app.
