The only cold plunge app that controls your chiller and sets your plunge from your own metrics. CONTROL YOUR CHILLER FROM YOUR PHONE Polar Dive talks directly to your chiller. Set the exact temperature, turn it on before you get home, and schedule cooling cycles around your week so the water is ready the moment you are. No other cold plunge app owns the tub. This one does. A DAILY PLUNGE BUILT FROM YOUR BODY Every morning Polar Dive sets a recommended temperature and duration based on how your body actually recovered overnight. Connect Apple Health, Oura, or WHOOP and your sleep, heart rate variability, and resting heart rate shape the plunge. Slept great? You earn the cooler end of your range. Rough night? Polar Dive eases off. Every recommendation stays inside a range capped at our safe maximum, so you push when you are ready and never past it. MEET URSA, YOUR AI WELLNESS COACH Ursa is your in-app coach, grounded in your own data. Ask why today is colder than yesterday, how to breathe through the first thirty seconds, or what your recovery metrics mean, and get a plain language answer built around you. Ursa explains the recommendation. It never overrides your safe range. BUILD YOUR COLD RÉSUMÉ Every plunge adds to your record. Track lifetime time in the cold, total plunges, best streaks, honored rest days, perceived difficulty, and how your HRV trends over time. Log sessions with the built in timer, snap a post plunge selfie, and share it straight to Instagram. KEEP YOUR GEAR IN PEAK CONDITION Get maintenance guidance for your Polar Dive chiller and tub, plus supply recommendations so your setup stays clean, cold, and ready. TAKE THE DIVE At home, at the gym, or outdoors, Polar Dive fits into your day and grows with you. Take the dive. Change your life.
