What does determining a location via iBeacons mean? If overland is using the iOS API to determine the location, shouldn’t it also use Bluetooth and the likes (which would include iBeacons in my understanding).
It's a bit more in the user's hand. You could put a beacon in your garage and one in your kitchen and send different events with OwnTracks depending on which one is close. It's a bit more granular and hyperlocal than iOS' location API.
