Developer IZE has just released an app called Find My Facebook Friends. The app basically works the same way in which Apple's Find My Friends works but connects to Facebook instead of Apple IDs. This opens up quite a few more people to “find” (for me and I’m sure most), considering exchanging Apple IDs isn’t exactly the first thing that crosses my mind when I get a friends information.
Some features that Find My Facebook Friends has that doesn’t show up in Apple’s own app are proximity alerts when a friend is close enough, sending messages via the Facebook app, and locations preferences based on each friends or list of friends.
The app was rejected twice from the App Store, not for being to similar in function to Apple’s own app, but for its icon and name. It was previously submitted as “Find My Friends for Facebook” and the original icon looked like a mix between Facebook’s and Find My Friends.
Find My Facebook Friends is now available for $0.99.
