Every county in England, from Northumberland down to Cornwall. More than two million walks measured across them. Tap any county to see what we hold there.
Ceremonial counties, from Ordnance Survey open data. A county is live when it has been surveyed and packed, which is a decision we make rather than a file that appears.

One thing, and it is not a petition. Create an account and walk one of these. Every county here has been measured against the map, and almost none of it has been walked by somebody who then said what was actually there. That is the part we cannot do from a desk.
The border is the one edge left. If a walk crosses into Wales or Scotland the app has to say it does not know, because we hold nothing there, and it will say so rather than guess. That is the next thing we build, and it is a bigger job than another county.
We would rather tell you where we cannot help than colour in a map.
