Cold Shower Timer turns every cold shower, ice bath or cold plunge into one clear number: how long it takes your heart rate to settle.
The cold hits as a spike. Your Wear OS watch shows your heart rate live, and the moment it calms down and holds steady, the watch marks it: Settled. Week by week, that moment tends to come sooner.
ON YOUR WATCH
- Big presets for wet fingers: 1, 2 or 3 minutes, or Next, which adds 15 seconds to your last session
- Live heart rate during the cold, with your peak
- The Settled moment, marked with its own vibration
- Optional breathing vibrations (in 4, out 6) and a tick every 30 seconds
- Works on its own, without your phone
ON YOUR PHONE
- Today: the heart rate curve of your last session with the Settled marker
- Your week at a glance: sessions, minutes in the cold, streak
- A phone timer for days without the watch, including hot and cold contrast shower rounds
Free: the timer, live heart rate, the Settled moment and your last 7 days.

Cold Shower Timer is a timer and a log, not medical advice. If you have a heart condition, ask your doctor before cold exposure.
