The most feature-rich free navigation app for Android we've seen: MapFactor puts at your fingertips a ridiculous amount of tools and options, including an accessible route calculator, simulator, and recorder (you can replay on the map completed routes), a configurable toolbar in the map window on which you can add indicators such as speed, linear distance, and time to destination/waypoint/maneuver, a potent search tool with Google support and ability to search by point of interest and coordinates, and accurate alerts and warnings for bad roads or speed cameras. Apart from not requiring a continuous Internet connection, this app also impresses with its wealth of options and settings. Using OpenStreetMaps data, MapFactor offers accurate turn-by-turn GPS navigation for most countries and allows you to download maps to your device or SD card for offline use.
