Let's talk chess apps

I'm sure by now, all technologically concerned recognize that there are an overwhelming amount of chess apps which have burst unto the scene recently. My most amazing finds were apps such as capablancapro, fischer pro , lasker pro etc. with all the games these guys have every played in tournaments as well as their best games. 

e+Chess books apps allows purchase of electronic chess books from everyman. So far, I have some of the starting out: ones and books from Jeremy Silman and Yassar Sierawan. These books allow the moves with arrows or chess notation touch scroll through the moves as appose to setting up a board and moving the pieces.

I also have one called GM chess classics. It's mostly loaded with chess puzzle books. Openings lite is a a must have. Then there is the popular tchess pro. Of course we all have or should have the app for chess.com. You can purchase chess ebooks through a nook app or kindle from Barnes and nobels. I'll list a few more..grandmaster (archive)...great chess.
