Interval Timer: Focus & HIIT

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.
