Sauna Log vs SaunaLogger

Sauna Log helps you run sauna and steam sessions with structure, consistency, and clean health tracking. Use your Apple Watch or Garmin 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.

SaunaLogger keeps track of every sauna session – how often you go, how long you stay and how hot it gets. LOG A SESSION IN ONE TAP Start the timer when you step in and stop it when you're done. Forgot your phone? Register the session afterwards. Electric or wood-fired, it's all counted. Works offline – sessions sync when you're back online. SEE YOUR HEAT Your calendar shows every sauna day, the yearly heat map glows brighter the more you go, and your stats add up total time, average session and your longest streaks. AUTOMATIC LOGGING (BETA) Got a wifi-connected sauna heater? Link your heater account on saunalogger.com and SaunaLogger records the temperature curve automatically – heat-up time, peak temperature and door openings – without you touching the app. SHARE THE MOMENT Add a photo to a session and create a share card with your stats and temperature curve, sized for feed or story. SAUNA CLUBS Create a club for your friends, family or workplace sauna. Everyone sees who's in the sauna right now, the club calendar, monthly and yearly stats, and who logged the most sessions. Clubs can be open, link-only or invite-only. PRIVATE BY DESIGN Your sessions, measurements and photos are yours. Club members only see the days you went, not your numbers. No ads, no tracking, and you can delete your account at any time from Settings. Available in English, Swedish and Finnish. SaunaLogger is developed by Second Oak AB for Hott Sauna.
