A standalone Wear OS watch face and complication to follow blood glucose data from NightScout, http://www.nightscout.info/.

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

Features:

- choice of mmol/l or mg/dl display units
- optimized for ambient mode / always-on usage
- complication for adding blood glucose data to other watch faces
