“No road data where you are yet” Coverage is currently Pennsylvania, West Virginia, Vermont, North Carolina, Tennessee, Virginia, Maryland, New Jersey, Kentucky and Delaware. Outside those, the app has nothing to suggest. More regions are added over time.
Loops take about 40 seconds Generating one means finding what is reachable in your time budget, ranking roads by corners, elevation and traffic friction, then routing several candidates and scoring how much of each is genuinely good road. The Saved tab opens instantly if you have a route already.
Will it work with no signal? Yes, if you save the route first. Tap a route, then Save for offline — that stores the turn-by-turn directions and downloads the map tiles. The Saved tab and navigation then work with no connection, which matters because the roads this app recommends are often the ones without coverage.
Sharing a route Select a route, tap Share route, and read the six-character code to whoever you are meeting. They enter it under Saved. No account is needed on either side. Codes are not secret — anyone with the code can open the route.
Why does it avoid dirt roads? Deliberately. Unpaved roads are excluded from both scoring and routing, because the app is built for cars that do not belong on gravel.
Why does it never show my top speed? Also deliberate. The app tells you where to drive, not how fast. It records distance, duration and which roads you covered, and it will not keep score on speed.
If a road is rated wrongly — a surface that has since degraded, a seasonal closure, or a route that simply is not good — email the road name and roughly where it is. Ground truth from real drivers is the most useful thing you can send.
