No clutter, no distractions - just what you need in the moment before, during and after a plunge.
Big enough to hit with cold, wet, shaking hands. No fiddly taps.
Switch units any time, and dial temperature in to 0.1° if you like to track it closely.
A configurable warning beep before time's up, plus a loud mode for when you really need to hear it.
Streaks, total dips, total time and average temperature, plus your last five plunges at a glance.
Every plunge is logged with date, time, duration and temperature - no need to write anything down.
No adverts, no sign-up, no account. Ever.
See every screen, from setting up your plunge to checking your streak.
