Let Rondivo keep time while you train.

Readable from a distance

The stage takes the colour of the phase (Prepare, Work, Rest, Cool-down); a large countdown, round and set, the next phase, a progress strip of all phases and the total time remaining.

Preset programs

Boxing, Tabata, HIIT 40/20 and Stretching are included; all can be edited and duplicated.

Program editor

Preparation, work, rest, rounds, cool-down, sets and rest between sets; the total duration is calculated instantly. There is no rest after the last round.

Named steps

In advanced mode a program is a sequence of steps, each with a name and a duration (circuit training); steps are reordered with buttons or by dragging.

Sounds and cues

Bells and sounds are generated with Web Audio; countdown beeps in the final seconds (duration selectable), volume, vibration and spoken phase names (on devices that support it).

Accurate timing

Time is measured as a difference of performance.now(); even if the tab is slowed in the background, the correct phase is shown on return.
