Organic Chemistry Reaction App 1.0.3.0

OCRA, the Organic Chemistry Reaction App, allows you to test your knowledge of organic chemistry reaction mechanisms by solving puzzles just like the ones chemists are challenged with every day - in the classroom and at work.
Built by chemists, for chemists, the puzzles are presented in an authentic fashion, exactly the same way chemists would draw them in a lab book, on a whiteboard, or in a textbook.
With a large and growing database of puzzles, OCRA is an essential tool for learning, practicing, and reviewing chemical reaction mechanisms.
