Good Choice

I like it. As others have written, this app is challenging and its helpful for learning about and remembering new info on a variety of topics. I like that its for a single player and improving ones own abilities, instead of having an opponent and trying to win.
I dont like the background music, but its easy to go to "Options" in the menu and adjust the volume for the music,(silenced), and the sound effects, (low).
Overall, a very user-friendly app!
