Interval: HIIT Workout Timer

INTERVAL is a HIIT timer and Tabata timer that gets out of your way.

Pick a preset and start: Tabata Classic, EMOM 10, 30/30 Endurance, Core Crusher, Pyramid Power. Or build your own interval workout in seconds.

CASUAL MODE: warm up, work, rest, rounds and cool down, set with big steppers you can hit with sweaty hands.

PRO MODE: any sequence of work and rest blocks, in any order, repeated for as many sets as you want. Circuits, ladders, EMOMs, complexes.

While you train, a huge colour-coded ring counts the interval down: lime for work, teal for rest. Countdown beeps, spoken cues ("Go, round three", "Rest", "Halfway"), optional vibration, and the screen stays awake so you never have to touch the phone mid-burpee. Pause, skip or end at any point.

Every workout you finish lands in your history.

No account. No sign-up. Nothing leaves your phone. A small advert keeps Interval free, never on the timer screen, and one Remove Ads purchase turns advertising off forever.
