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.
