Works on latest iOS and WatchOS

Update: It works on the latest updates to your iPhone and Watch.
I still like the app and use it daily.
Two things that should be added:
1) Auto sleep detection
2) When you delete a sleep session on the iPhone, it should also delete it on the Watch. As it is, after you delete a sleep recording and the Watch re-syncs with the phone app, the deleted sessions show up again! Irritating.
Otherwise its a useful app. Just needs some more work.

Like others have said, it used to work until the update. After the update, the icon is not on my Watch and cannot add it from the phone.
Once this is fixed, Ill up my review because otherwise I use this app daily and find it very useful. The only functionality I wish it had was auto-sleep monitoring, otherwise it was really good.
