LocTracker

Using GPS, LocTracker tracks your location when you are walking, running, biking, sailing, riding, gliding, or flying, … The App simply keeps track of your whereabouts over the last 24 hours. It shows time, and geo coordinates and calculates distance, speeds, and changes in altitude. Your track is visualized on a Google map (requires Internet access). You can save (part of) it for later reference. Outliers (measuring errors) are corrected. Saved tracks can (to some extent) be edited, deleted, and exported in GPX format. Several regional and display settings can be configured. Apart maybe from Google Maps, none of your locations are sent to any servers. Your data is yours only on your device only! The accuracy entirely depends on the GPS accessibility and location capabilities of your mobile device.
