Sounds like you've been doing a good amount of experimenting as well! If you use the default startMonitoringSignificantLocationChanges method you'll get updates sporadically depending on things like what other apps are using location services, so it looks pretty crazy in the wild. It will also skip over many geofences if they are smaller than a kilometer or so. Our SDK manages this intelligently and can trigger the smaller geofences more reliably without the phone being in super-accurate mode the entire time. If you send your contact info through our site we'd be happy to talk about this further! https://developers.geoloqi.com/enterprise
