MapFactor: GPS Navigation for PC is a very good app to find your way when you are travelling. This is a turn by turn app, which navigates you with every minute detail on the app. And the best part about this app is that, it is completely free! The app uses OpenStreetMaps data to gather map information. One great feature of this app is that, it does not need an internet connection to operate, as the maps and the app are all installed on the SD card.
Another great feature of this app is that, it gets updates for free every month. There is a very useful voice guidance feature, and there are many languages to choose from as well. You can even avail route planning on door to door basis, and the app even does cross-border routing at your request. And users can even change between 2D and 3D modes to get realistic map effects.
