this one is pretty useful. unitill it got to the end where i had to type out "north Atlantic treaty organization" and "phonetic alphabet" seventy-two times. also i found a glitch where two cards are sort of overlapped. it would show one card said i was both wrong and right, then read two things out at the same time.

Actually, the voices are more rough and hard to understand on this one, vs the other one I commented on. Also, there's this thing called color. It's free. Still, I like the idea. This could have more content, too. No need to focus on a small group.

Nice learning surface.
