It seems that every application coming from Prolog suffers from the same shortcomings. They are meant for the iPhone and they are old materials recycled over and over again under different names. I downloaded a few and decided to delete all of them. A waste of time.
Wow!
This is a fabulous app!! I just finished the first four of the free lessons and already learned so much! I would consider buying the full version, but I think together with the book it's quite expensive. Thanks for this great app!
