Missing something...

Doesnt feel like an essential (lol) app anymore. Theres nothing that cannot be found in his Elements In Action and a good reference app like EleMints or Wolfram-Alpha proper.

Missing mass spectroscopy lines and other pertinent info that is included on the flashcards (paper, not app) & book. Kinda clunky in its display, though it loads smoothly. Ok app in the $3-5 range, not more. Not sure how much it took to produce this, so I do not want to discredit the designers & author; I do enjoy the paper flashcards & book. But I wont mince words: I dont remember there being info cribbed from Wolfram-Alpha in the physical copies or this app in 2010; even if it makes it easier to keep entries up to date, I would have liked to have seen the original info; or entries comparable to other periodic apps. Seemed the book was less minimalist. Its cool to see actual examples, but I wanted more.
