imagine using the screen of your iPhone as a braille cell, that allows you to mark the points with just one finger. With this very friendly app you will be able to type faster than sighted users. The text will be written in the last line of the screen and you could check it and edit it on the fly. With just some easy gestures the pointer will move letter by letter. the text will be pasted into the clipboard every time the app is in foregrond by default, you dont have to do it.
