QuizUp

QuizUp is an app that allows you to play seven-question, multiple choice trivia games against real (and sometimes, admittedly computer-generated) opponents in the subjects of your choosing.

The image above is from the web version, but the smart phone version doesn't look all that different.

I'll offer up three community points for each of the following achievements...

• levels 10 or 20 in chemistry
• levels 10 or 20 in periodic table
• levels 10 or 20 in name the elements
• levels 10 or 20 in high school chemistry

The name the element category is a really nice way to learn the elements. You will have to know this, though.
