I strongly do not recommend this app. I was charged after accidentally tapping a button, even though I had no intention of making a purchase. I don't even know what this app is or what it offers. I contacted customer support immediately, explained that the charge was a mistake, and asked for a refund. They refused without any real attempt to help. Please be extremely careful. One accidental tap can result in an immediate charge, and based on my experience, getting your money back is impossible.

I don't know what to think I. I used it to access my Facebook and Google accounts and it would not let me access to my accounts. What good is an authenticator when it never let's me access my accounts. To me, this is more frustrating and not worth the app.
