NavFree GPS UK & ROI for iPhone – £free Best free sat nav for iPhone There are lots of low cost or free sat nav apps for iPhone, making it one of the best sat nav phones you can buy. Our favourite is NavFree GPS from GeoLife, an app that includes lots of professional quality features like turn-by-turn navigation, voice guidance and automatic re-routing. You don't just have to take our word for it either. The app has already won rave reviews on the iTunes App Store with an average rating of 4 stars. NavFree GPS uses the OpenStreetMap (OSM) system created by users – although that can mean that rural routes aren't as well covered as urban ones.
