## Ultra Plunge Contrast Therapy Reviews in United States

### ***** "Active responsive developer"
The app 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 this app
-- tlpz94, 2025-01-17

### ***-- "So close!"
Love the basis of the app. 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!
-- T-Rav65721, 2025-01-17

### ***** "Great"
The team at Ultra Plunge has been very accessible and enjoyable to work with over the time I’ve had the app.
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 
This app also motivates me to keep my treatments and tools current in my training!
Good job team!
-- donaldtrumpenstein, 2025-01-16

### ***** "Amazing cold plunge companion"
The Ultra Plunge app is a game-changer for anyone serious about cold therapy. The app is incredibly user-friendly, with customizable plunge timers, temperature tracking, and guided breathing exercises that make every session effective and enjoyable. The interface is sleek and intuitive. The motivational tips and wellness insights are a bonus that keeps me consistent. This app has transformed my recovery routine—highly recommend it to beginners and pros alike!
-- Anil Motwani, 2024-12-07

### ***** "Good!"
It has all the features to be amazing but is not quite there. For some reason it doesn’t save a plunge automatically after ending it. When you get out of cold water you are usually trying to get dry and warm , not mess with your watch. Today I also discovered that if you’re not connected to the internet (e.g: out in the woods with no data) the app won’t load “the products” meaning you can’t start any of the activities…. For the price you’d think this was better developed, so yea kinda disappointed and hoping these issues can be solved so I can fully appreciate the features and improve my rating of the app.

Edit: responsive developer improved on the issues I had we will see how well it work, thank you
-- ozginch, 2024-12-06

### ***** "Great app"
This app 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
-- TinyDancer305, 2024-10-14

### ***** "Ridiculously well designed"
Love using this app 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.
-- Ray99095, 2024-10-02

### ***** "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 this app does it all and a lot more. Also works great in my sauna. Highly recommended
