Great to log and see some stats such as sleep and hrv

I have been using for several days now, and it is really easy to use and great to track your sessions. I still have to see how it affects the body in term of hrv and sleep since it takes several weeks

Finally a good app for Sauna data!

I love this app, I’ve been looking for a way to actually track how sauna impacts my recovery, and this is exactly it.
It pulls your data from health and shows the real effect on your HRV and sleep scores.
Super clean and well made.

FAQ

What is Sauna Score?

Sauna Score is a health and fitness app designed to help you understand the impact of your sauna sessions on your body's recovery and overall health. It tracks metrics like Heart Rate Variability (HRV), resting heart rate, and sleep quality.

How does Sauna Score track my data?

Sauna Score pulls your HRV, resting heart rate, and sleep data directly from Apple Health. It is compatible with popular wearables like Apple Watch, Garmin, Oura, and Whoop.

Can I set my own sauna routine in Sauna Score?

Yes, you can pick and commit to a specific sauna protocol within the app. Sauna Score then tracks whether you adhere to your chosen cadence, such as the Laukkanen protocol (4-7 times/week) or the Søberg contrast method.

What kind of results does Sauna Score provide?

Each week, Sauna Score presents your HRV, resting heart rate, and sleep data for 'on target' weeks versus 'off weeks'. It also shows your eight-week trend and compares your metrics against others of your age and sex.

Does Sauna Score give a daily readiness score?

Yes, Sauna Score provides a daily 'heat readiness' call each morning: Go hot, Go gentle, or Skip. This call considers your HRV, recent sleep, resting heart rate, and banked heat exposure.

Does Sauna Score have ads?

No, Sauna Score is ad-free. It focuses on providing a clean and uninterrupted user experience for tracking your health data.

What is the sleep score based on in Sauna Score?

The sleep score is a 0-100 read derived from five inputs: Performance (duration), Efficiency (time awake), Restorative (Deep + REM), Bedtime (drift from median), and Interruptions. These targets align with AASM consensus.

Is Sauna Score available on Android?

Currently, Sauna Score is an iOS-first application and is native to Apple Health. It is designed to work with the Apple Watch and other compatible devices on the iOS platform.
