UPDATE 2016/04/18: This app is currently for sale on Flippa!
I built this simple Apple Watch and iOS app as a test of working with “WatchKit” and designing for a very small screen.
The app is free and provides a watch “glance view” for quickly checking your iPhone's battery level from your Apple Watch. For those with/without Apple Watches, you can receive customizable notifications of various battery levels, but this requires an optional in-app purchase ($0.99 USD) to enable forever.
Download it for free from the App Store today!
