Sauna Cold Plunge Timer

A simple protocol timer for heat, rest, and cold-plunge sessions. Set sauna minutes, rest minutes, and cold plunge seconds in Connect IQ settings, then run rounds from the watch: select or tap starts and pauses, next page or swipe up skips a phase, previous page or swipe down resets the phase, and menu or swipe left resets the whole round. The screen shows the current phase and time left, and the watch beeps and vibrates at each phase change so you do not have to look at it. Free 7 day trial, then one-time purchase. No subscription, no account, and no network. This is a timer only and is not medical guidance. Use it outside the heat or wherever your specific device is rated for the environment.

Adds a free 7 day trial so you can try it before buying.
