My flatmare and I are interested in the convenience of a 'Family Location Sharing' app - being able to see each others locations, so we can see when each other might be on the way home from work, or at the supermarket etc etc. We're looking for an app that doesn't need you to request permission each time, but where as two consenting adults we can can just fire up the app to get each others location at any time. Obviously battery drain is a concern.
Anyone have any experience with this?
