RingBack is a simple app that enables you to easily setup your lock screen with your name, a phone number to call and a reward (optional) in the event you lose your iPhone, iPad or iPod.
Otherwise, if you have locked the screen on your device the finder is unable to contact you. But, if you have not locked the screen your information (including your contacts, email and banking as well as other information) can be easily accessed. With Ringback it means your data is locked but the finder of your iPhone, iPad or iPod can still call you to return your device and claim the reward offered.
Update for iPhone to adjust lock screen so compatible with iOS 10
Ratings and Reviews
Works as described and worth 99 cents
If I lose my iPhone the screen will tell the person who finds it who to call so I get my iPhone back.
So simple it's almost brilliant!
With Family Sharing set up, up to six family members can use this app.
