The Sanokuni app has been majorly updated!

We want both veteran sauna-goers pursuing totonoi and light users who have just started enjoying saunas to enjoy them safely and comfortably. With this in mind, we have developed features that allow you to record your sauna experiences and find your optimal totonoi.
By syncing with your sauna device to quantify totonoi, and looking at the Activity Summary to reflect on past data, it helps you connect with your own physical sensations.
Please find your own unique way of enjoying saunas!
We have made most of the features free because we want as many people to use them as possible. As for past data storage, we charge a fee due to server costs.
We plan to continuously develop new features in the future by incorporating your feedback. The revenue from the paid version will power the development of new services, so we appreciate your support!
Below are the changes:

- Connection via Bluetooth with the sauna device: Data Sync, implementation of Notice function based on target heart rate, display timeout settings, display brightness adjustment, and lift-to-wake setting.
