A minimal standalone Wear OS 2.0 watch face and complication to follow blood glucose data from NightScout.
We already have numerous CGM watch face options across the various smartwatch platforms, including NightWatch and xDrip+ on Android that provide featureful Wear OS watch faces when installed alongside their companion Android phone applications.
The motivation for this watch face is to utilise Wear OS 2.0's standalone app support, this is useful because it means:
-
the watch can be paired with either an Android phone or iPhone and still be usable as a NightScout display, utilising the phone's data connection when necessary
-
the watch can be used as a NightScout display away from its paired phone wherever it has a working internet connection (wifi or integrated cellular)
-
the watch face can be installed and configured entirely on the watch itself
