HIIT Interval Workout Timer

Interval training, zero guesswork.

HIIT Interval Workout Timer runs any work/rest interval structure — Tabata, classic 30/30 HIIT, EMOM, or fully custom timing — with a big countdown, a progress ring for the current phase, and synthesized audio cues (no sound files to load) marking the start of each interval plus a 3-second countdown beep before every transition. Pause and resume mid-workout without losing your place, and background color shifts by phase so you can tell work from rest at a glance without reading the screen closely.
