qooTrack is a great and useful movement assistant for active people. It is a slim and but powerful app based in particular on the measurement of speed, distance and direction by using GPS signal. It saves your GPX data on your phone or SD card, which can be used in third party software like Google earth afterwards. Check your track on the maps (internet connection needed). Start application first, then go to homescreen and add the widget. Compatible with S^3 / Anna / Belle Smart Phones.
