It's actually a $50 app that you don't need – Recover - Data Recovery and Backup Review

Another waste of time if you don't like paying $50 for something Apple already has. I lost messages, contacts, notes after another bad Apple update(9.2). I found the answers on line. Google your problem and some blogger will have a list of fixes. Some of these sites are covers for another app they are charging money for that is again not needed. Most problems are in family sharing when you don't have separate emails signing each family member. I found answers easily and they were quite easy.
