Starting a journey with cold water? This app has free guided content and inspirational stories with plenty more to come in this space. For Brass Monkey customers, this app helps your bath or barrel become even smarter: • Use it to connect your bath or barrel to the Brass Monkey cloud for remote monitoring, support and software updates • Control your Brass Monkey from anywhere and set eco schedules for it to be cooling only when you need it to • Access product guidance and get reminders of maintenance tasks • See the status of your Brass Monkey and get notified of any issues • For those with a Brass Monkey zero degree ice generating product, this new app gives greater control of the bath’s patented ice cycles, offering 3 levels of ice generating intensity. The new features this app brings from the last: • A redesigned interface to make navigation and bath status more intuitive • As customers were telling us they want more control over exactly when the cooling engine is on or off, we’ve also simplified the scheduling feature • We’ve simplified the ice cycles on ice baths. So now, under 2 degrees, you can now set the intensity of ice production, removing the guesswork of using a temperature setting to get ice • Improved responsiveness between the app, Brass Monkey cloud and your bath • Greater set of maintenance reminders and issue alerts, with push notifications to your phone • Water flow rate alerts for chiller engine products.

People feel better after a sauna. They just can't prove it. Existing fitness apps treat sauna as an afterthought, a manual log entry at best. And nobody takes their phone into a sauna anyway. Without data, the habit feels invisible. Without proof, habits fade. Saavu is a sauna companion that pairs with your Apple Watch. Your Watch goes in with you. Saavu reads what your body does in real time. Start a session on your phone. Saavu reads your heart rate live from your Apple Watch via HealthKit, guides you through heat, cold, and rest phases, and shows your body's response in real time. Leave the phone outside. Your Watch keeps the session going. After each session, Saavu shows your heart rate curve, HRV recovery, and a face state, a simple visual that maps to how your body responded. Over time, you'll see your resting heart rate shift, your HRV improve, and your readiness score climb. These are your numbers, compared only to yourself. Saavu maps saunas, spas, and cold plunge venues near you. Check in when you arrive, and your sessions are linked to the places you visit. Can't find your local? Submit it. The venue database grows with the community. A quiet calendar on your home screen tracks your consistency. No gamification noise, just an honest record of the days you showed up. Weekly charts show your trend at a glance. Free users get unlimited session tracking, venue discovery, check-ins, and streak tracking. Saavu Pro unlocks full session history, HRV trend analytics, personalised wellness insights, session sharing, and your wellness score. Saavu is not a medical app. It does not diagnose or treat any condition. All data is for personal wellness awareness, your body's story, told in your own numbers. Heat. Cold. Thrive. - Terms of Use (EULA): https://saavu.app/terms/ - Privacy Policy: https://saavu.app/privacy/
