This is a demonstration version of a watch face designed to operate with the xDrip experimental Type 1 Diabetes management phone app. Note that currently this is not supported in the mainstream xDrip releases. If you wish to use it, please build the xDrip-NS-Dev version from my github repo.
This first version is both a demonstration of the xDrip Pebble Framework and a working watch face with rich features. It is also available for installation (side load) from xDrip (see caveat above)
The settings allow you to configure what metrics and data you want to see, and how you wish to display it.
