Sporcle is free today for all your quiz needs. Known as a website and iOS app, now available for Android through the Amazon Market. Previously, Android users could only get their question/answer needs fulfilled through the Android Market, but always for a price.
Amazon has you covered, though for only 15 more minutes. Why do I bother, simple, because I care.
Read the reviews from other downloaders and you'll see that with slow reflexes or subpar smartphone typing skills, you will not have too much fun with this app. Its probably best to stick with the site.
