This is a custom clock face for the Fitbit Ionic and is a combination of Fitbit's "Moment" clock face and Lee Doel's "Minimal Style" clock face.
I created my own version in order to remove the activity switching (since I didn't care) and add weather instead of a battery level.
This is mainly just for my use, but if anyone wants to download the source and install it themselves, you'll just need to add in a valid OpenWeatherMap API key in the apiKey variable inside companion/index.js.
