Interval - HIIT Timer

Interval is a fast, focused interval timer for HIIT, Tabata, EMOM and any work/rest training you do.

Build a workout in seconds — set your work, rest and rounds, or start from a ready-made Tabata, HIIT or EMOM preset. Then press start and move. A big, glanceable timer, color-coded phases and clear cues keep you on pace without staring at the screen.

BUILT FOR TRAINING • Work, rest and rounds you control, with round rests between sets • Tabata, HIIT and EMOM presets to start from • A clean preview of the whole workout before you begin

STAY LOCKED IN • A large timer with color-coded WORK / REST phases • Two-tier progress: where you are in the round and in the whole workout • Audio beeps and an optional voice cue on every phase change and the last 3 seconds • Haptic feedback so you can train heads-down • Keeps running with the screen locked and in the background

LOCK SCREEN & DYNAMIC ISLAND • A Live Activity shows the current phase and countdown on the Lock Screen and in the Dynamic Island

YOURS, AND PRIVATE • No account, no sign-up • No tracking, no ads, no data collection — everything stays on your device

SIMPLE PRICING Use Interval free for up to 15 workouts with every feature unlocked. A single one-time purchase — Interval Pro — removes the limit forever and unlocks accent themes. No subscription, ever.
