One of the best things about iOS 7.1 is the new changes for location changes in the background even after closing an app. I have an app idea that needs to be running with iBeacon, but previous updates were too slow and unreliable.
This also works the same way with geofencing, however I can’t see an effect with IFTTT at the moment.
Apple really should inform about these sorts of changes though, as the effect on privacy with geofencing apps is probably something that should be considered.
Will wait and see about the effect on battery life too though.
