The Watch app on an Apple Watch Ultra: the rooms list, a TV room, and a music room.
How it works, step by step
Install from TestFlight

Previous, play, pause, next (music rooms)
Favourites (music rooms)
TV room or music room?
The Watch decides the same way the iPhone app does: by what the speaker is really doing. A soundbar playing its TV input — or sitting idle on it, TV off — is a TV room and shows the TV presets, Mute and the format, nothing else. Anything else is a music room, with playback, the music presets and favorites. Switch the soundbar to music on the iPhone and the Watch screen follows within a few seconds.On your watch face
Somos has complications for round, corner and wide slots: the Somos logo, Room, Now Playing, Volume, EQ Bars, EQ LEDs, Sleep Timer, Favourites, Presets, Play/Pause and Next Room. Each tap lands on its own screen: an EQ complication opens the room’s EQ screen, Sleep Timer opens the timer choices, Favourites opens your favourites, and Presets loads the room’s next preset. The quickest start is the ready-made face: on your iPhone, open the menu, tap Apple Watch, then Add Infograph face. See Watch Face for every complication and how to add it.The EQ and sleep timer screens
- EQ — opened from an EQ complication. It shows the loaded preset’s name, its EQ as bars and its values in words, with the room’s preset buttons underneath to load another. With no preset loaded it says No preset loaded. Pick one below.
- Sleep timer — opened from the Sleep Timer complication. Tap Off, 15 min, 30 min, 45 min, 60 min or 90 min. While a timer runs, the time left sits at the top. See Sleep Timer.
The Rooms button
A room opened from a complication is the top screen, so it has no back arrow. Press the Digital Crown to go straight back to your watch face, or tap Rooms in the top-left corner to see all your rooms.The card in the Smart Stack
When Live Activity is on and the iPhone is running iOS 18 or later, the Lock Screen card also appears in the Watch’s Smart Stack. It is a read-only glance, not a remote:- TV room — the room name, the volume, and the audio format.
- Music room — the room name, the volume, what is playing and, when the service reports one, the format.
What it cannot do
- Save or rename presets, or move a slider — presets are saved and named on the iPhone. The Watch loads them; it has no Bass, Treble, Night Sound or Speech Boost controls of its own.
- Browsing music — there is no browse or search. It plays what you already saved as a Sonos® favorite.
- Press a button from the watch face — a complication opens the Watch app first; Apple only lets widgets press buttons directly on iPhone and iPad.
- Grouping — rooms cannot be grouped or ungrouped from the Watch. On a grouped room, the Crown turns the group’s volume.
- Play, pause or skip on a TV room — the buttons are not shown there, because a TV input ignores them.
- Away from home Wi-Fi — the Watch needs to reach your speakers. If it cannot, the room screen says Can’t reach your Sonos. Join your home Wi-Fi or bring your iPhone. A room that has dropped off the system says so too — check it has power.
