What's New in Sauna Metrics

1.9.0

October 28, 2026

iPhone Duo: opened flat, the live timer splits at the hinge, with the large ring on one side and the rounds and controls on the other. Stood half open on a table, it becomes a timer you can read from across the room. Christmas: from November 28, a Christmas tab holds an advent tree. Each December day with a sauna opens a pocket, along with the Nordic traditions of the season and your year's recap, for everyone. Each round and each break can now be edited, while logging a session and once it is over. The total time and the start follow. The score shows as you fill in a session: you see what the sauna hat, water or a few more minutes in the heat would add. Stats: new insights (your best period, your sauna day, your rhythm, what would raise your score) and clearer breakdowns. Apple Watch, Watch Outside mode: End round, Not a round and Start round, for when the sensor misses the watch coming off or going back on. A session in progress comes back if the app is closed. Apple Watch: the round's timer stays on the watch face once the watch locks, sessions hold up better when the app is closed or the watch comes off, and Settings explains the three ways to use the watch. Also: fixes and smaller improvements.
