So close!

Love the basis of UltraColdPlungeSauna . However, it is not recording my heart rate while in the sauna or cold plunge. Using the ultra 2 watch. All permissions have been given. But still not working. Would give five stars if I got that going!

Great

The team at Ultra Plunge has been very accessible and enjoyable to work with over the time I’ve had UltraColdPlungeSauna .
They have added key features that for me take treatment to next level.
After 2 months of use i now can track where the benefits really are and adjust my training accordingly
UltraColdPlungeSauna also motivates me to keep my treatments and tools current in my training!
Good job team!

Amazing cold plunge companion

Just what I was looking for

Since starting my polar plunge journey I’ve been looking for an app that will track water temperature, time, and heart rate on my watch and UltraColdPlungeSauna does it all and a lot more. Also works great in my sauna. Highly recommended

Ridiculously well designed

Love using UltraColdPlungeSauna to track my cold plunges. My session starts as soon as I dunk my wrist in the water and shows me instantly how cold it is. Even has guided breathing on the watch app.

Great app

UltraColdPlungeSauna makes tracking my cold plunges effortless. I love seeing the water temperature and guided breathing right on my watch and being notified when my time is up

Active responsive developer

UltraColdPlungeSauna is great at tracking the cold and hot sessions, the developer is active and in 1day they release the update to better track cryotherapy, im very happy with UltraColdPlungeSauna
