FAQ

Do I have to install the watchOS app?

No.
 
By default your iPhone will send notifications to your watch. You can configure this behaviour in the Watch app on your iPhone.

Can I install the watchOS app without the iOS app?

Yes!

Do the iOS and watchOS versions sync data?

No.
 
I think for most people, having the app installed only on their iPhone is the right decision, but for people who want a more complex arrangement, having two separate configurations is more likely to be what they want.
