it is a excllent app
This is great!
Perfect app , amazing work
Updated - as of 1/17/17 I really like it. The app is a series of theory lessons and practice based on those lessons. The free portion imparts the idea to beginners that overall position is more important than any one piece, and practicing the lessons teaches the beginner how to think positionally and try to plan ahead. (Toying with the idea of purchasing the full version. If I do, it will be the first app I've ever paid for, which, for me, is saying something.)
