Great Pedigree
Our original Topo Maps app
dates back to 2009 when dinosaurs roamed the earth.
The old app has proved consistently popular over the years with users who
appreciate its simplicity and reliability. It remains available and is
still supported.
If you have the original app, its maps will be shared automatically with
the new app. You can also copy over your saved waypoints.
