This app provides GPS capability such as current speed, distance, elapse time, altitude, ascent and descent metrics. The focus is on simplicity and ease of use. Stand alone GPS units cost hundreds of dollars. This provides a majority of the same functionality for a fraction of the cost. There are no advertisements! It is intended for hiking, biking skiing, running or most any outdoor activity where these basic statistics are of interest. Mapping of current location as well as displaying, saving, recalling and erasing of routes is also provided. Place marks can be created and saved. Backup your routes and place marks with iTunes file sharing. Most GPX and KML files can be read. Note that continued use of the GPS running in the background can dramatically decrease battery life. Listed trips are for demonstration only.
