Requires iOS 7 or 8
One of the worst feelings we associate with our devices is fear, the fear of losing our iDevices and the chance of never recovering it back. When we lock our devices down with passcodes we do this because we value our privacy. When we lose our device we don't want them rummaging through our contacts/photos/etc to find out who the device belongs to.
IfFound adds a convenient button on the LockScreen which makes it easy for someone who's found your device to find out the best way to contact and return your iDevice back to you
Compatible with other popular LS tweak such as JellyLock7, Forecast, SubtleLock and IntelliscreenX
