iOS App Zone Entry/Exit issue

Hey all,

I seem to have an issue with the iOS app with two zones that are close to each other.
I get notifications that I entered one when I am in the other etc.
To be clear the zones are close, but they do not overlap.

My (uninformed) speculation is that this is caused by poor GPS accuracy on the ios significant location change API.

From below link I understand that there is a tradeoff between efficiency (battery) and accuracy.
Can this be configurable?

your problem must be related to the location accuracy of the phone (can be 200m).

You can use a ble beacon.
