Looking for a typing tutor app Years ago, I learned typing by a program named Typing Tutor, on DOS. XD

Now, my son is using a MacBook and I am teaching him how to type. What software/website you recommend to learn typing on a MacBook?
The Typing Cat



I like it because:


it's free
fast
gives nice progress
supports multiple layouts (qwerty, dvorak, colemak, workman)
looks good
You don't need to install anything - it's webapp
i'm creator and i'm proud of it and made it as sideeffect of teaching myself Colemak. But I can be subjective u need to try it yourself to verify my statements :)
