iTag is a proximity-based GPS game where you compete against your Facebook friends at a virtual game of tag! Track your Facebook friends who are playing iTag on a map to see their location. Get close enough to them, and tag them to earn points. The closer you get the more points you earn. But be careful, if they tag you first you won't be able to tag them back for 4 hours.
You can also see how you rank against your Facebook friends and how you rank against the entire iTag community.
