ipad touch typing

Hi. I know this is not the appropriate forum to post. I am sorry in advance for that.

Basically, a friend of mine is homeschooling her kids. And she wants to know of the best touch typing apps for iPad.

I have so far recommended Typing Fingers by Foriero as I have personally used it and have found it to be the best among the touch typing lot.

I just wanted to know of your opinion. Do you consider any touch typing app which is better than the one I have mentioned? I am asking because i want the best for my friend and I think I should double-check, even though I have full faith in Typing Fingers.

Thanks a lot in advance.

You can probably ask a moderator to move the tread the appropriate place would be in General > Open Topic.

But can't say so much about typing apps. Isn't the normal iPad keyboard enough? Or is there a special need for a third-party app?
