About

EigenTime Timer is a general-purpose sequence timer for describing and running any flow that unfolds over time: prepare, work, rest, repeat — freely nested and looped.

The same timer covers HIIT, Tabata, stretching, breathing rhythms, focus sessions and anything else you can express as a sequence of timed phases. Specific routines are just presets; the engine knows nothing about any particular activity.

It runs entirely in your browser. There is no account and no server storing your sequences; anything you build stays on your device.

To count visits and measure loading speed, the site uses Cloudflare Web Analytics. It sets no cookies and reports only the page path and performance data — never your sequences or share links.

This is not medical or training advice. Presets are example timer configurations, not recommendations.
