Setting a geofence:
1. Add a marker on the big map for the point in the center
2. Change the optional settings for the radius of the geofence and the vibration pattern
3. Add the geofence --> You'll get notified when you enter the geofence or your position is in the geofence
Disclaimer: I can not ensure that the geofence function as expected. Improper positioning may result in malfunction.
