My Location

Sets and stores GPS lat and lon of your preferred city

To access, you have two options:

In the App Loader once My Location is installed, click on the 'Save' icon next to it - and you can choose your location on a map.

On Bangle.js go to Settings -> Apps -> My Location

Select one of the preset Cities, setup through the GPS, waypoints (if installed) or use the webinterface from the AppLoader
Other Apps can read this information to do calculations based on location
When the City shows ??? it means the location has been set through the GPS

Example Code

const LOCATION_FILE = "mylocation.json";
let location;

// requires the myLocation app
function loadLocation() {
  location = require("Storage").readJSON(LOCATION_FILE,1)||{"lat":51.5072,"lon":0.1276,"location":"London"};
}
