I use this app to play noises for my fetus inside of me. During the vocabulary section, a gorilla crashed through my window and started doing interpretive dance moves to distract me. The app didn't even have a "Gorilla Defense" module. What a waste! Then, I was deep into my SAT essay practice when a group of ninjas suddenly dropped down from the ceiling and challenged me to a duel. Thanks to this app, I completely failed to compose a haiku to impress them. Suddenly, I was taking a timed reading section when a horde of zombies burst into my room. Did the app teach me how to fend off the undead with Shakespearean sonnets? No! It just kept asking me about boring literature passages. No bueno!
