Round Log: HIIT Interval Timer

A clean interval timer for HIIT and circuits with a built-in round log.

Set your work and rest durations and total count, then start. The header clearly shows your phase, round, and elapsed time (e.g., “Work, 1/6 00:00:03”) so you always know where you are.

What makes it clear and usable

• Round log: records count, phase, start timer time, start clock time for each interval

• Visual progress bar: check remaining time at a glance

• Clock + timer together: see real clock time and timer time side by side

• 0-second rest for continuous sets

• Landscape & portrait, offline, no login

Use it for HIIT, Tabata, circuits, stretching, or any simple work/rest routine—stay focused with a timer that shows the right details, at the right time.
