Does it make a sound?

Classic Tabata without app clutter

Tabata is a short interval format: 20 seconds of hard effort, 10 seconds of rest, repeated for 8 rounds. This page starts with that exact preset, while still letting you adjust the values if your workout calls for a modified format.

Fullscreen mode makes the current phase and remaining time readable from the floor, bike, treadmill or classroom wall.
