This app should be pulled. It will hold important messages hostage unless you give the maker money, and all under the lie of doing it for the users security. Be warned, if you use this app for app for password resets, they will not give you access until you pay them. It'll work for other messages, giving you a false sense of trust, but if determines that an incoming text is for resetting a password for whatever you've gotten locked out of, you won't see it until paying the ransom.
