• Q) Why create another geofence plugin

  A) I felt like the integration or bloat in other geofence libraries (stay, notifications, etc). I also didn't like that Google Play Services were required in Android which required your device to be online when creating the geofences. This did not work with my requirements

• Q) Why use a cross platform GPS library for Android?

  A) James has done a ton of work around the Android geolocation mess. I didn't want to duplicate this. I just wanted to attach to an event and set the desired accuracy

• Q) Yes, but what about google play services?

  A) The amount of code necessary to register a geofence as well as all of the junk that came with it made it annoying and no less of a drain on the battery
