Now Playing Shortcut
It's literally just a small complication for the
Now Playing View for your Apple Watch.
For some reason Now Playing doesn't have a small complication. True, it does have an icon at the top of your watch when you're listening to something, however if you want to quickly resume where you left off you need to open up your audio app to do that, while now playing can do that for you faster.
WatchOS doesn't support something like
UIApplication.shared.open() as far as I could tell, but it does let you embed a
Now Playing View in your app, so that's all this app is.
Sketch should export all the relevant image sizes to the correct locations if you export to the root.
