Our N95 was let down by a slow fix time, leaving us looking slightly foolish when friends asked where we were, only to pull out the latest gadget which five minutes later was still trying to access satellites. The iPhone on the other hand provides an almost instant location via triangulation of phone mast signals and known wifi points.
Accuracy is limited but it works and provides a quick and easy way to orientate yourself in the city, and now thanks to Navizon you can track your friends as well. Navizon is an application that builds on the iPhones 'locate me' feature, it tracks both your and any friends location every 10 seconds issuing you with an alert when they come into a predefined range.
You can add your friends to your Buddy list with a click of a button and then simply click on "Buddies" to see where they are on a map. Your friend will receive an notification with a link to click on and you will be able to see each other's location.
The YouTube movie embedded below provides a walkthough of Navizon:
This is the first example we have seen of near real-time location tracking of people on a consumer device. It is perhaps a landmark moment in geo-software and an indication of the route ahead as we are all becoming increasingly 'geo-located'.
