These days just about every new Android phone comes equipped with Google Maps Navigation, the free turn-by-turn GPS navigation app that helped put Android on the map. Odds are pretty good that if you bought your phone in the last 8-12 months, it also has a paid carrier navigation app as well. Add one more to your list of navigation options, as Navmii’s iPhone app Navfree has made the jump to the Android Market.

So what makes Navfree different from the navigation apps you’re already using? One word: crowdsourscing. One of the biggest hurdles that GPS navigation has to overcome is the rapid changing of highway and road conditions, due to construction, events or other unforeseeable circumstances. Nothing ruins a good roadtrip like a sudden and unavoidable 10-mile detour. Navfrree aims to solve this problem by taking map corrections from its users. So if  the traffic circle on your way to work is out of commission for a few weeks, you can let other Navfree users know, and vice versa.

The interface looks like your basic navigation app, but it’s free, so I won’t complain. It’s nice to see that is comes with maps for Europe, North America, Australia, New Zealand, India, South Africa and Latin America, perfect for the next time youi want to go around the world in 80,000 miles. Navfree is available now in the Android Market.
