@arlogilbert Background work on iOS is a tricky beast, but we do our best. We've found that the most reliable way for the app to wake up in the background is what we call "Location-assist syncing", which uses (low-battery) Location Services APIs to wake up the app whenever you arrive at or leave an area. You can turn on location-assist in the app's Sync Options. We also do a sync whenever a geofence established by a Location Applet is crossed.
