Just saw over on Facebook a band I follow push this iOS app called Chinese UP. From looking at the iTunes description, it's a game with Chinese characters, words, and pinyin to use as a (temporary) replacement for flash card testing on common characters/words. Just wondering if anyone has tried this out yet and what their thoughts are.

I just gave it a go. Bit of fun but not particurlarly useful. Probably do the free ones but won't pay for the other packs.
