3 stars: So far the features of the app are well designed, but the ads are RIDICULOUS! They're extremely obtrusive, designed to trick you into accidentally clicking on them while you're in the middle of something (they cover the whole screen). I would give this 4.5 stars (and round up to 5) if not for that. The app mechanics are professional, but the advertising adds a cheap amateurish feel to the entire experience. I have several GRE apps and this is the only one that does this (for the others you don't have ads on paid versions). This means that despite this app being well-designed, I find myself avoiding this one in favor of the other apps. I am not interested in ads, and I don't want to see them. But if all you did was force me to see them, that would be obnoxious and distracting. This goes beyond that, to unforgivable, because you try to trick us into clicking and interrupt me in the middle of answering questions WHICH ARE TIMED!
