Geofencing isn't entirely one-sided: You can see when your friend has put a notification on you, though you can't remove them. Head to the Me tab to see if you've been geofenced; if you have, the outline of the Location Services arrow appears next to their name. You can tap their name to see what they're tracking, though there appears to be no way to get rid of the geofence currently without removing them as a follower altogether. (You can hide your location from followers temporarily by enabling the switch in the Me tab, but that doesn't wipe out the geofence--only ignores it while you're hidden.)

As always, while these features are nifty for those you trust with your location, you might not want to let every person you met at a conference have permanent access; for those, we recommend using the app's Temporary Event feature, which lets you set geofences and track location for a limited amount of time.

Find My Friends's last new perk in this update is Friend Suggestions; now, when you tap the Add Friends button, a pop-up window will hover below the To field with the email addresses of iCloud contacts you haven't added to Find My Friends.
