Sauna 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 to Apple Health, including:

Heat type (sauna or steam room)
Session duration
Heart-rate data
Energy burned (active and total)
Cold shower selection
The iPhone app gives you quick control of your default timer presets, heart rate thresholds and session history.

Free to try for 3 sessions, then unlock with a one-time purchase.
