Plans for Apple watch app in near future?

+1 for an Apple Watch app.

To those saying it'd take too many resources for a company of this size to create and support one, I disagree. It should be a very lightweight extension of the iOS app and is one of the few actually valuable use-cases for an Apple Watch app.

If you are using an apple phone and have the lock screen control for Sonos active it will do that automatically now with no 3rd party app needed.
Only if the Sonos app is the last app you've opened. Otherwise "now playing" drops the connection to Sonos and shows nothing playing. (Same with Control Centre and iPhone physical volume controls)

I think this is more of an iOS issue than Sonos, however, it doesn't negate the fact that a dedicated Sonos Apple Watch app would vastly improve the experience and reliability.

There already are decent Sonos watch apps

There seem to be a lot of excuses for not having an Apple Watch app. According to this forum, no, there aren't any good Sonos Apple Watch apps. And no matter what, it's not the same as a first-party developed/supported app.

Remember Reddit and Alien Blue? It was barely passable, but once Reddit bought and supported it as their own, it got far better.

What are issues with all the current available?

As previously posted....

Downloaded sonobit... volume kind of works. Nothing else seems to. Pretty bad.

That was one version. Not sure why didn't work haven't tried using in year or so.

As far as I can tell without purchasing them, none of the 3rd party Apple Watch-enabled apps allow you to browse through and select 3rd party music services (like SiriusXM). Would be nice to be able to switch Sirius channels on our outdoor speakers from my watch while in the pool. If I am wrong, PLEASE let me know! This is another case for a sonos-made Apple Watch app...I can't imagine they would leave that feature out.

I just updated to iOS 11 and watchOS 4, and the lock screen (iPhone 7 Plus) and Now Playing (Apple Watch Series 2) are both showing the current song playing, allow you to pause, skip tracks, and adjust the master volume. I received a phone call while music was playing, and the screens on both devices went back to normal. I was able to get them both back up by opening up the Sonos (Beta) app and then locking the screen. Seems buggy and unstable at first look, but will have to see how it performs over time, and with updates.

Has anyone else experienced this?

If you're using a Beta app, there's a more appropriate place to be discussing it. This is a public forum.
