The problem with most turn-by-turn navigation apps for cellphones is that they are outrageously expensive. Not so with Waze. In fact, the app is totally free—and it even turns the driving experience into a fun little game.

The video explains the service in detail but, in a nutshell, Waze maps are entirely user generated. Users can also relay a heads up to others about accidents and other hazardous driving conditions. It even plays a Pac-Man type of game with drivers who are exploring uncharted territory. As you map the area, your car icon will eat up dots and collect points. Apparently, the app also pays attention to your speed to help determine traffic conditions and disable the keyboard to prevent users from typing while driving.


The problem here is that crowd-sourced services have had limited success in the past, so Waze is fighting an uphill battle. But since it is free, it's not like you have anything to lose by giving it a shot. Waze is available for iPhone, Android, Windows Mobile, Symbian and other devices. [Waze via TechCrunch]
