Random Number Generator +

I got this app to use for studying Russian vocabulary. I have a book of 10,000 Russian words, arranged and numbered in order of frequency. Word number 1 is most common, word number 10,000 is least common. As the number of words I memorized got larger, I started using RNG to randomize my review. I open the RNG function, enter "1 to X [where X equals the highest-numbered word I've studied]" and test myself on the word corresponding to the number that's generated. It's a great way to efficiently sample my recall of the vocabulary in a short amount of time. Great app!

I feel like this app is about as random as a random number generator can get. My only problem is that when I go to use it and I have any audio running, it will stop the audio. Not worth giving it any less stars though. Everyone should have this app sitting on your device.

The app works really well, does many kinds of useful rng and seems statistically random enough. However, the animations for some of the new modes (yes-no, for example) are unnecessarily long and annoying, to the point that I just don't use those modes anymore. Spin the bottle is amazing but often it takes half a minute for it to stop spinning. Gotta tone those animations down, or make them optional, and the app would be perfect.
