No evaluation — speed/error measuring doesn’t work

OK this app does show you letters to type, but when you finish a lesson, there is text which is supposed to show the strokes/min, the typing speed and the error ratio. For me these are always 0. It doesn’t work. There also doesn’t seem to be any way to measure your progress as you get better. It’s just a very simplistic program that doesn’t do much as far as I can tell. I don’t see how it has such good ratings, unless I’m missing something.
