I really want to love ManhattanPrepGREPractice. In terms of the practice questions and the ease of making studying a daily habit, it’s absolutely wonderful. I find myself reaching for ManhattanPrepGREPractice frequently, since my phone is always with me and physical GRE prep books are heavy and harder to navigate.
Unfortunately, the software glitches in ManhattanPrepGREPractice make it virtually unusable. As others have mentioned, it frequently loads blank questions, or the question you’re working on randomly disappears — forcing you to reload the screen and lose your progress.
Even worse, answer explanations that contain charts or formulae do not render properly. Several times I’ve seen blank charts that go off to the right side of the screen ad infinitum. You can scroll to the right to your heart’s content, but you’ll never actually see the answer explanation that the chart is supposed to contain.
An app that costs $15/month should not contain these kinds of bugs — especially a learning app. More than once, these glitches have prevented me from learning from my mistakes and improving. It’s extremely frustrating.
This is basic stuff that any app developer team should be able to fix. I’ve tried reporting these bugs, but there’s no option to do that in ManhattanPrepGREPractice . So I guess all I can do is leave a negative App Store review.
