It's nicely done! I'm not sure that I like the fact that the text doesn't mean anything... I guess it's in purpose so that you have to look at the words and not type mechanically for words you know but at the same time, I spend a lot more time figuring out what is going on...

I just gave that app a try there - I like it.

I second (or third now!) that I don't like the meaningless words. Makes it much harder to type them I reckon, and some of the words seem to be real words, but with missing letters, so you find yourself typing the real word, which is wrong!!

I learned to type "correctly" on keybr.com (with a little startup in gtypist). I probably owe you some money :) 50wpm and gaining.

Well done! Thank you!

That's a nice app.
