What does it do?

Im sure theres something to recommend this but its in no way a free app as promoted. In order to do anything, you must pay yearly. Even then it does not act like a traditional internet security program. The only benefit I saw was my backup transfers from a perfectly safe app were blocked. When I asked for a refund after deleting the app, the app no longer worked but I have no record of any refund. Just be sure to read about this app carefully before buying. It gets worse. Im writing many months later after the above. This is a total fraud and a scam. This app does nothing at all. I never received a refund and have paid for two years of NOTHING AT ALL. The app does not do anything. I have since been victim of the very thing it claims to protect against: apps not carefully monitored by Apple that add junk and bill your credit card high amounts. Apples heavy handed way of dealing with this if you complain is to deny use of the credit card you use. If it happens more than once or twice you can easily run out of new credit cards to give them and be locked out of the app store
But dont count on this app to help. Remember I could find nothing it will do in the PAID VERSION except offer to back up contacts which Verizon and other apps already do.
