Turn-by-turn GPS navigation apps are a common tool found in the App Store; however, TapNav looks to build on existing standards by incorporating augmented reality. Unlike other GPS applications, TapNav forgoes any built-in maps and instead uses a live feed from the iPhone's camera. Large AR discs are placed on top of the video feed, providing users with a visual path to follow. Standard voice directions are also featured, along with a fully tap-based interface and customizable gadgets.
