This is my blood glucose watchface. It can work with any glucose data source.

COMPANION APP

This watchface uses a generic Pebble Glucose Protocol, and can therefore be made to work with any data source (github.com/mortenfyhn/pebble-glucose-protocol). You need a companion app or other source that sends glucose data using the this protocol. Each companion app must be added to package.json.

Options:
• MiniMed Pebble Bridge - an experimental MiniMed pump companion app (github.com/mortenfyhn/minimed-pebble-bridge)
• xDrip - hopefully one day
• Direct MiniMed pump connection - this is what I use (github.com/mortenfyhn/PebbleOS)
• Make your own app implementing the same protocol (github.com/mortenfyhn/pebble-glucose-protocol)
