I just tried it on my original Watch running WatchOS 3.0. There was no music on it, I created a playlist on the iPhone, synced it, turned my phone off completely, and was able to play the music from the Watch via Bluetooth.
Missus is away on training so I'm doing the shopping. Can anyone recommend an app that I can write a shopping list on my macbook/iphone and then view it on the apple watch?
We use an app called "Shopper". It syncs across our phones so we can both add to the list as needed throughout the week. I think they have a Watch add on but think it's a yearly subscription along with a few other extras.
Thanks for the suggestion. Looked at it on the App Store, it might be free for what I want to use it for, but then I stumbled across something called Wunderlist which looks good so will give that a shot.
