When to use Interval Timer
Useful for exercise, drills, study repetitions, presentations, or any repeating work/rest pattern.
How to use Interval Timer
Set the inputs that matter for this task, run the tool, then copy or reuse the result when the page offers that action. Inputs stay visible so you can adjust them and run the tool again without starting over.
Timing behavior
Running time is derived from timestamps rather than counting interval ticks, so the display can correct itself after normal browser throttling.
