It plays slowly, but about the right pace if you're bringing a family along with you, i.e. you're all playing together against the phone, I found. The questions are presumably sourced from a public domain trivia question set, but it's quite large and I've not had the same question repeated yet.
An impressive set of languages, especially considering the number of questions. That's where quite a bit of the 130MB download comes in, anyway; (right) the interface is simple and gently animated.
The usual lifelines are there and work well. As usual though, as you approach the 'million', the questions are so hard that your answers will be mainly random!
