By using the "Zero" app and engaging in these activities, YOU VOLUNTARILY ASSUME ALL RISKS, known and unknown, associated with your participation. 2. Mandatory Medical Consultation Cold exposure places extreme physiological stress on the body. You must consult with a qualified physician before starting any cold exposure or breathwork regimen. This is especially critical if you possess pre-existing conditions (e.g., cardiovascular disease, high blood pressure, diabetes, epilepsy, asthma) or are pregnant. Never practice ice bathing if you are under the influence of alcohol or drugs. 3.

Log your cold plunge and sauna sessions. Build streaks. Sync to Strava and Apple Health. Degree Daddy is a cold plunge and sauna tracker for people who take their recovery seriously but don't need a lifestyle brand to do it. Timer, logging, streaks, sync. Works on iPhone, iPad, and Apple Watch. APPLE WATCH — NEW Start a session from your wrist and leave your phone in the locker. A big timer, live heart rate, and a tap on the wrist at each milestone. Set the temperature with the Digital Crown when you finish, and the session lands in your iPhone history and Apple Health. TIMER One tap to start. A big, readable timer counts your session while encouragement messages keep you in. Switch between cold plunge and sauna mode. Lock your phone and the timer keeps counting on the Lock Screen and in the Dynamic Island. SAFETY CHECK ALARM An optional alarm for each session type that goes off when your chosen time has passed — 5 minutes for cold plunge and 25 for sauna by default. It does not contact emergency services. LOGGING Save temperature, sauna type (dry, steam, or infrared), a 1–5 star rating, and your location after each session. Tag it Home, a nearby venue — gyms, spas, pools — or your city. Everything stays on your device and syncs across your iCloud devices automatically. STREAKS Consecutive day tracking so you can see if you're actually being consistent. Current streak and all-time best, right on the home screen. Miss a day? The app offers to continue your streak so travel and rest days don't reset your progress. STRAVA SYNC Strava has no cold plunge or sauna activity type. Degree Daddy fills the gap: push any session to Strava as an activity — "Cold Plunge - 2:45 at 42°F" — with your sauna type, location, and streak in the description. Attach your session card as a photo so your followers know what you're about. APPLE HEALTH Every session writes to Apple Health as a workout, with heart rate when you use Apple Watch. Whoop, Oura, Garmin, and anything else that reads HealthKit will pick it up automatically. SESSION CARDS A clean, branded card with your duration, temperature, streak, and location. Share it or save it. PRIVACY No account required. No ads. Your data lives on your device and syncs through iCloud. Anonymous usage analytics via TelemetryDeck and crash diagnostics via Sentry.
