What you see is what you get
Well, heres the app in a nutshell: you get a screen-sized version of the period table. Tap on one of the elements and you get hyperlinked to the Wikipedia entry on that element. (and no way to get back, except, of course, to start again at your home button.)
You get two menu choices at the bottom of the screen: (1) display the table (see above), or (2) buy the paid version.
