## Description

**Interval Timer: HIIT & Tabata** is a colorful, easy-to-read workout timer for HIIT, Tabata, circuit training, boxing, gym sessions, running intervals and more. Create custom work and rest phases, nested rounds, named intervals, sounds, colors and vibrations. Save workouts as presets, reorder phases with drag and drop, and share timers through a link.

The timer continues running with the screen off using an ongoing notification with pause, stop and skip controls. A full Wear OS app lets you build and run workouts directly on your watch, with synchronized presets and vibration alerts. Use it for CrossFit-style WODs, EMOM, AMRAP, jump rope, stretching, rehabilitation, meditation, breathing exercises or Pomodoro focus sessions. No account or sign-up is required, and all timer features are free.
