Work Rest Calculator

Easily track work and rest with WorkRestCalculator!

Stay on top of your intervals with two flexible modes:

Manual Entry – log your own work and rest times (great when using an external clock, class/group setting).

Automatic Timer – let the app run your rounds for you (when it's just you getting sweaty).

Pick the style that fits your workout:

Ratio – rest is proportional to your work (e.g. 1:1, 1:2, 2:1, 3:1, or Tabata 20s/10s with audio cues).

Set – choose a custom rest duration (e.g. 60 seconds), applies the same rest to each round.

Every – define the total time for each round (work + rest, e.g. every 3 minutes), EMOM style but can be any duration of time.

Now with configurable presets, quick tips, and a Time Calculator for quick time math outside your intervals.

Simple, effective, and distraction-free. No data collection—just clean, easy time tracking for better focus and performance.
