About
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 — your total time left stays on the Lock Screen and in the Dynamic Island. The screen stays awake while a workout is running, and when you return to the app the current phase is recalculated instantly, without replaying missed cues. 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.
