A Fog of War map of everywhere you have been

HoldMyTrack covers the world in fog and clears it wherever your tracks go. The streets, parks and trails you know stand out, and so does everything around them you have never set foot in: your next walk is wherever the fog is.

How the fog clears

Fill it in

More ground clears more fog, so bring in as many walks, runs, rides and trips as you like.

Go somewhere new

The fog shows what is left. Pick a street, a park or a trail you have never been to, go, and watch it clear the next time you bring the track in. Switch on points of interest to see playgrounds, dog parks, viewpoints, waterfalls and historic sites from OpenStreetMap; with the Android app, stand in one for 30 seconds to capture it.

Frame any view of your fog and save it as an image to share. Your map itself stays private.
