Sauna Log

Track every sauna and steam session on Apple Watch with live heart rate, calories, timers, and seamless Apple Health logging.

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.
