[New] Introducing "Totonoi Karte": find the sauna routine that suits you ๐ฃ
Oct 9, 2026

Thank you for using Sanokuni!
Here's what's new in app version 4.0.0 ๐ฃ
Introducing Totonoi Karte, a new way to look back on your sauna sessions, sleep, recovery, and activity in one place. Home and My Page have also been redesigned.
1. Find out what works for you with Totonoi Karte

Totonoi Karte brings your records together by period, so you can look back on what works for you and how your body is changing. Open it from the Karte tab at the bottom of the screen.
- Score trend: how your T-Flow Score, Sleep Score, and Recovery Score moved over the period
- What moved your scores: how much your scores differed between sessions with and without conditions such as alcohol, number of sets, or time of day
- Note trends: which answers came up most in your Reflection notes and Sleep memos

Questions like "How long after the sauna should I go to bed to sleep well?" or "How much does drinking lower my Recovery Score?" start to get answers from your own records.
2. Compare with others

See where your trend stands compared with people of the same gender and age, or with high T-Flow scorers.
๐ Premium Plan feature โโ With the Basic Plan, you can view every karte and What moved your scores for up to the last 90 days. With the Premium Plan, you can also choose longer periods such as 6 months, 1 year, or all time, and compare with others.
For details on reading each karte, see the Guide to Reading and Using Karte.
3. A redesigned Home

We rebuilt Home as a place to look back on your last sauna session and head out to the next one.
The actions people use most on Home are sauna-related: creating a log, syncing data, and checking in. So we placed everything about your sauna sessions from the top down, letting you see your last result and what to do next as soon as you open the app.
- Recent sauna session: see the T-Flow Score of your last session, and how your sauna, cold bath, and rest times compared with usual. You can also tell when the score is still being calculated or failed, and resend right there
- To-dos: see at a glance which of AI deep dive, Reflection notes, Sleep memo, and unsent logs are still left
- Right now: your current numbers in one place: Recovery, Last night's sleep, and This month's sauna sessions
- Map and Totonoi - 1: jump to the map to find your next sauna, or to Totonoi - 1
The button at the bottom right shows "Sync" while your SAWATCH is connected, and "New log" otherwise. Check-in and Notices are now together at the top right. The SAWATCH update notice is also a compact one-line banner that stays out of your way.
4. Other improvements
- The top card on My Page has been redesigned
- Re-running scene detection when editing a sauna log is now available to everyone
- Stamp screens display better with larger text sizes
Update the app to the latest version (4.0.0) and give it a try.
That's all for the Totonoi Karte release from Sanokuni.
Thank you for your continued support of Sanokuni!
