Apple Watch works just as before, and every session comes together in SUNA on iPhone: history, Sauna Score and Journey. To add Garmin, pair it in More → Garmin first, then install the app from Connect IQ. On an empty Home screen, a short three-slide guide shows how to use your device: simple steps for Apple Watch, detailed START button controls for Garmin.
