I often felt uneasy when I had to take unfamiliar routes. I worried about getting lost and whether the path I was following was really the one I had memorized. It would be nice to have a GPS device with navigation, but in reality, they are often expensive. So I made this app. This app displays GPS route data created by others or routes generated from map websites, exactly as they are. If your current location is on the route, you are going the right way. Continuously looking at the screen while riding is dangerous, so I recommend checking it only briefly when you are unsure of the route. However, in the current location mode, the screen can be kept on continuously. • If an error occurs, please email the GPX / TCX / KML / KMZ file you are using.

Open KMZ files with your iOS device! KMZ Loader is designed to open KMZ files, which are compressed KML (Keyhole Markup Language) files. Google Earth can open KML files on its own, however KMZ's will not load properly without being decompressed first. KMZ Loader can decompress a KMZ file into a KML file allowing it to be viewed both in Google Earth and as source code. Any KMZ files imported into KMZ Loader will be stored in My KMZs and can be deleted by simply swiping over it. For more information on KML files: http://en.wikipedia.org/wiki/KML
