Wandrer Helper

Enables you to overlay KMZ files from Wandrer onto OpenStreetMap tiles, then follows your progress as you cycle around and complete all the roads in your chosen area - so you don't need to travel roads more than necessary!
Red roads change to green as you complete each section.
Can add several overlay files at the same time, and store your travels on the device ready for your next outing.
No registration necessary, absolutely free.
*note: some downloaded KMZ files have a problem which causes the app to freeze. Please contact the developer for a fix if this happens.
