GPS tracking: run, bike, ski, hike, everything!

Replace your old hand-held hiking / running / biking GPS with Retrace. Retrace makes it simple to record a GPS log of your activities. Simple displays highlight distance, speed, and elevation changes. If you have data, the map tab shows you where you are on the map; if you do not have data (or have it disabled to save battery), a grid-based view is presented. Elevation profiles are also shown. You can also disable data usage from the options page so you can track your activities in areas where you want to avoid data charges. If you ever have any problems or questions, the options page has a 'send feedback' button. If you contact us, we will try to sort out any problems ASAP! Retrace is great for: * running * biking * hiking * walking * downhill/x-country skiing * off roading (ATV, motorcycle, etc.) * any other activity you want to record your trip Retrace supports a variety of export options: * Strava * RideWithGPS * GPX: Used by many online services like RunTracker and Endomondo. * KML: Used by Google Earth. * GeoJSON: Used by leaflet and GitHub. Retrace also makes it easy to tag you activities so it is easy to go back and look at tracks for past activities. Permissions: Retrace requires only two permissions to operate: 1) GPS location; without this the app will be unable to plot your position. 2) Shared files; this option is only required if you wish to export tracks. Specifically, this permission enables you to attach your exported tracks to emails. Retrace does not read or write to any directory other than /retrace in your shared files. Strava/RideWithGPS upload note: When you upload, be sure to send the upload from the same account you log into the online system with. Your activity will show up on the site after a few minutes.
