Mr. Krip ,

The App for Learning (and Teaching) Organic Chemistry

This app has merged two all-to-often disparate attributes of educational tools: good science and good artistic / design. Although Alchemie is still in the process of refining their approaches to this design, this app synthesizes theory with an intuitive approach that makes chemical principles much more palatable for the student. Give the app a serious try; it is sure to become indispensable for first and second year chemistry students (and teachers too!).
