What's New in Version 1.1
+ iOS 3.X compatibility
A very basic app
This app is ok but I don't really recommend this for studying unless you want a free app.
First off, it's kinda of a pain to go back and fourth the way it's set up. There needs to be a next button of some sort. Or even better there needs to be a button that randomizes the ions to better suit it for studying. Another thing I don't like is something that you can see in the screen shots which is when I select an ion, let's say Ammonium, it takes me to another screen that says Ammonium. . . Ok as if I don't remember what I hit a second ago. It needs to show the symbol and charge right away instead of me having to scroll down the page to view it. The advertisement bar is kind of annoying where it's located at top, wish it was at the bottom.
As it stands in the current version I would not recommend this app for studying. It's just not set up well for that purpose. I'm currently in a chemistry class and knowing all of the ions is a must. I am having better success with an app called Polyatomics, which is better suited for studying, but it cost a dollar.
Good app for free
It took me a couple seconds to figure out I had to scroll down to see the formula for the given name or vice versa; no tapping or anything. Other than that, it's does exactly what it says: saves you time from making flash cards! I've only used it for about 20 minutes so far, but I haven't had any glitches!
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
