When we created Learn Thai Alphabet with Memory Aids To Your Great Adventure the tech wasn't there to create this kind of interactive learning application.
I ended up paying a few developers $$ to create/code an app for me. Unfortunately, it never worked. Not once.
The good news is, a year or so later the tech was.
So we jumped on and into it and created the Learn Thai Alphabet application (you can demo it below).
Initially, there were no sounds and fewer quizzes but, following customer feedback, we added more and more and more to it.

The goal is to learn the Thai alphabet, right?
We sell our book Learn Thai Alphabet with Memory Aids to Your Great Adventure on another page of this site ($19.99 at the time of writing). However, if you buy the LTA app, above, you get the pdf version of book as well, with out compliments.
