Sauna Log vs Sauna Tracker & Session Log

Sauna Log helps you run sauna and steam sessions with structure, consistency, and clean health tracking. Use your Apple Watch to start a session fast, choose sauna or steam room, run your preferred timer presets, and monitor live heart rate plus active and total calories while you’re in the heat. When a timer ends, you can stop or extend immediately for the next round. Sauna Log records your session details, including: - Heat type: sauna or steam room - Session duration - Heart-rate data - Energy burned: active and total calories - Sauna temperature and humidity - Cold shower selection Remember your usual temperature and humidity settings, so recording regular sessions takes seconds. The iPhone app gives you quick control of timer presets, heart-rate thresholds, session history, and longer-term progress insights. See your heat time, active days, heart-rate response, calories, and sauna-versus-steam patterns across weeks, months, and years. Optional monthly reminders help you return to your progress and stay consistent. Free to try for 3 sessions, then unlock with a one-time purchase.
