Offroad is an app that allows you to display offroad rights of way easily on a map.

Many mapping programs show pathways or roads, but only when zooming in on the map. Or they might not show access at all. With Offroad, you can move the map to where you want to show paths, click search, and the app will download and show an overlay of the paths at any zoom level.

This makes it handy for planning routes to link offroad sections.

The app also has a search function that will let you search for drinking points, toilets, and other points of interest.

When you're ready to save your route, click "Save" and the route will be saved for offline use.
