Have you tried an app to teach yourself how to play the piano?

I used to have that Mini Piano App.. It would work well on a big tablet if you had one.. It said it was suppose to be able to teach you how to play but i could never figure out how to get it to do it.. But..

My kid whom has a weekly piano lesson with a teacher, tried a couple apps and they both totally sucked.

I tried with synthesia

With recorded tunes?

Back in the early 80's my aunt had an electric organ with keys that lit up to help teach how to play it.
