Other Comments: 

This app was free when I got it, but it was only free for a day or 2, so I put it as paid to prevent confusion and hateful emails. Some buttons have weird lables, but they are very very easy to know what they do. It say control and then share or settings, so it works rather well. Remember to turn off voice over when using the app, but to turn it back on when sharing or editing settings.
