I like how it is simple to use and you can scroll down to find the answer. I did catch a mistake on acetate. It is actually CH3 COO-

Totally useless. I thought this would be like a flashcard format, but it simply names a bunch of polyatomics. It doesn't even match the names with the formulas

For the users that complained it was simply a list and not like flashcards, I say this: scroll down. A simple swipe will reveal the formula/name of the ion. Simple app, but useful.
