Interval Timer: Focus & HIIT

Focus with Pomodoro, train with HIIT. Phase changes come through with sound, haptics, and notifications even when locked. Free to use, Pro removes ads for good.

Whether you're settling in to focus or about to move, this is one interval timer for both.

Switch between Focus mode and Workout mode with a single tap, and each one greets you with its own timing defaults, color, and wording. In Focus mode the work phase is called "Focus"; in Workout mode it's "Work." Breaks are called "Breathe" and "Long Break" — no mechanical countdown language, just a bit of warmth while you push through.

Timing is calculated from elapsed seconds since start, not a countdown that decrements — so coming back from the background or a locked screen never leaves the display out of sync.
