A perfect circular watch face, that gives you a lot of information in one glance with customizable colors using 15 different themes
Pick a color theme you like, or let it use another color theme every hour or every day automatically! When Do Not Disturb is enabled, the watch face turns to Dark Mode, so it is even more eye friendly at night.

Of course it shows the current time, weekday and date, but also:
 - Time of sunrise and sunset on your current location
 - Current temperature, condition and min-max temperature for today
 - Most recent GPS-coordinates (from the most recent recorded activity) and distance to home (home location has to be set manually in Settings once)
 - Progress on your activity for the day (goal for active calories per day has to be set manually in Settings once)
 - Current Heart rate
 - Battery level indicator
 - Phone connection indicator
 - Alarm ON/OFF indicator

For instructions on how to change the settings of the watch face (via either Garmin Express on your computer, the Connect IQ Store App or the Garmin Connect Mobile App) see: https://forums.garmin.com/developer/connect-iq/w/wiki/14/changing-connect-iq-app-settings

* This app calculates the number of active calories burned, thanks to Garmin Forum Users markdotai and topcaser for the formula and code (https://forums.garmin.com/developer/connect-iq/f/discussion/208338/active-calories#pifragment-702=2). 
* The sunrise and sunset times are calculated by using the formulas and constants found in examples on the website of the National Oceanic & Atmospheric Administration (https://gml.noaa.gov/grad/solcalc/).
* The distance to home is calculated by a function I wrote, inspired by the formulas found on https://www.movable-type.co.uk/scripts/latlong.html.
