Great tool
This is an excellent app for general enthusiasts or for people using it for tests. Ive used it for both; can definitely say that this app is the reason I nailed the verbal reasoning on the GRE. Highly suggested. It loses one star for being in a larger aspect ratio that doesnt auto-scale to the iPhone 6 size, i.e. icons and text in the app appear larger than they should.
