Startup Idea: City Exploration Tracker App

Startup idea to create an app that tracks (in the background) a user's movement through a city, highlighting the areas the user has already explored to facilitate further exploration of unvisited areas.

It would be great if there was an app that tracked (in the background) where you walked/drove in a city.

When I'm exploring new areas, sometimes its hard to know where you've been and where you still want to explore.

If there was an app that highlighted all the areas you've been, that would be a great recourse to know where you still need to explore.
