Waze is a 100% free turn-by-turn GPS navigation application that provides real-time traffic updates, plus all kinds of cool social and geo-gaming elements with Twitter, Facebook and Foursquare integration, that actually make commuting fun. Wazers can actively update one another on traffic, police traps, construction, speedcams and more – and because it’s user-generated, the more people who use it, the better (and more addicting) it gets!
