Altaflip: Sauna & Cold Tracker

Sweat Loss & Hydration Coach

Free · In‑App Purchases · Designed for iPad

Sauna, cold plunge and contrast tracker with sweat loss and hydration Finally, a sauna app that does more than just track time. Altaflip calculates your sweat loss and tells you exactly how much water to drink after each session. Using research from Finnish sauna studies and peer-reviewed thermoregulation science, the app accounts for your body weight, session duration, temperature, and even which bench you sat on. SAUNA APP WITH SWEAT ESTIMATES Most people leave the sauna dehydrated without realizing it. Altaflip estimates your fluid loss based on: - Body - Sauna temperature and type (traditional, infrared, steam) - Session duration with sweat onset delay modeling - Bench level position (upper benches are significantly hotter) - Your heat acclimatization from recent sessions - and more... Then it calculates how much to drink to properly rehydrate, including electrolyte recommendations for longer sessions. BENCH LEVEL INTELLIGENCE Saunas have massive temperature differences from floor to ceiling. The thermometer shows the temperature at head height on the top bench, but sitting lower changes everything. Upper bench can be 20 degrees Celsius hotter than lower bench. Select your position and get estimated calculations. TRACK SAUNA, COLD PLUNGE, AND CONTRAST THERAPY Three session types, each with tailored tracking: Sauna: Traditional, infrared, or steam room with temperature and bench level Cold: Ice bath, cold plunge, cold shower, or outdoor swimming with cold dose calculation Contrast: Alternating hot and cold rounds tracked as a unified practice Cold sessions track your weekly cold dose based on temperature and duration. RESEARCH-BASED PROTOCOLS Built-in protocols from published studies: - Finnish Longevity: Based on the 20-year study of 2,315 Finnish men showing 40 percent lower all-cause mortality with 4-7 weekly sessions at 80 degrees or higher - Deliberate Heat: Heat exposure for health optimization - Cold Exposure: Progressive cold adaptation with weekly dose targets based on the Soberg protocol - Contrast Therapy: Structured hot-cold alternation Set your weekly target within each protocol range and track compliance. The app shows which sessions qualified and your progress. RELIABLE SESSION TIMER Timestamp-based timer that stays accurate even when your phone is backgrounded or the app closes. Recovers your session automatically if interrupted. Large display optimized for glancing. DAILY HYDRATION TRACKING Track water intake alongside your sessions. Your daily goal adjusts automatically based on body weight plus any sauna session deficits. Visual progress ring, quick-add buttons, and weekly trends help you stay on top of rehydration.
