Store description excerpt

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 body weight, session duration, temperature, and bench level. SWEAT LOSS & HYDRATION Estimates your fluid loss based on body metrics, sauna type (traditional, infrared, steam), duration with sweat onset modeling, bench position, and heat acclimatization. Then calculates how much to drink, including electrolyte recommendations for longer sessions. BENCH LEVEL INTELLIGENCE Upper bench can be 20 degrees Celsius hotter than lower bench. Select your position and get adjusted calculations. SAUNA, COLD PLUNGE & CONTRAST THERAPY Sauna: Traditional, infrared, or steam with temperature and bench level Cold: Ice bath, cold plunge, cold shower, or outdoor swimming with cold dose tracking Contrast: Alternating hot and cold rounds tracked as a unified practice RESEARCH-BASED PROTOCOLS Built-in protocols from published studies: Finnish Longevity (KIHD cohort, 40% lower all-cause mortality at 4-7 sessions/week), Deliberate Heat, Cold Exposure (Soberg protocol), and Contrast Therapy. Set weekly targets and track compliance. APPLE HEALTH INTEGRATION Sessions sync to Apple Health as workouts. Hydration syncs bidirectionally. Heart rate data from BLE monitors flows into Apple Health automatically. HEART RATE ANALYTICS Connect any standard Bluetooth heart rate monitor (Polar, Garmin, Wahoo, CooSpo, Scosche) for live HR during sessions. Post-session analytics include estimated calorie burn, thermal load scoring (TRIMP), cold shock response tracking, and heat acclimatization trends. Insights tab shows adaptation charts over time. HEALTH BENEFITS TRACKING Five-tier adaptation model (Building to Elite) scores your weekly practice against published research thresholds. Track adaptation timelines for both heat and cold. SESSION TIMER Timestamp-based timer that stays accurate when backgrounded or closed. Recovers automatically if interrupted. DAILY HYDRATION TRACKING Daily goal adjusts based on body weight plus session deficits. Visual progress ring, quick-add buttons, and weekly trends.
