Garbage app and dont trust this

Whatever you do, do not trust Random developers with your logins. If you look at all of these apps that send videos to Snapchat you will see that they are all the same with a few design changes in the same group is behind all of them (violation of Apple dev agreement). If they are shady enough to do that just think what they could do with anything you do in the app.
