The GPS market has changed dramatically the past number of months as smart phones have become popular navigation aids for people on the go. With a simple download, a GPS app can be ready to use on your smart phone within minutes. Consumer Reports has tested a number of the iPhone apps over the past few months and have recently updated the reports with new information.

There are apps from traditional GPS companies like Magellan, Navigon, and TomTom, but other companies have jumped into the navigation arena such as Gokivo, iGo My Way, MotionX, and Sygic. The lesser-known companies provide lower-cost options, but the larger, brand-name companies have many years of experience and resources to provide development and support.
