Pick Roadtrippers when the price has to be visible before you start. Free allows 1 saved trip and 3 stops, which is a test, not a cross-country route. Basic ($35.99/year or $11.99/month) raises that to 3 trips and 20 stops. Pro ($49.99/year or $16.99/month) allows 5 trips and 50 stops. Premium ($59.99/year or $19.99/month) allows unlimited saved trips and 150 stops. The homepage offers a 7-day trial. Autopilot uses patterns from over 42 million trips on the platform. You can still edit the stops.
Pick Wanderlog when the phone and the other people on the trip matter more than a printed subscription price. The homepage links to both stores and puts the map next to the itinerary. Route optimization auto-arranges a route. Offline download is listed. The page does not say that download is paid, and the Pro page text we fetched had no dollar figure.
Pick Furkot when the constraint is how many hours you will sit in the car. You set a daily driving limit, it orders the stops, and it suggests where to sleep. Lodging links open a booking site with the dates filled in. The page says Furkot earns a commission on those partner bookings. It does not describe a chat assistant, and it does not list a price.
Use a navigation app for the actual drive. These three plan the order of the days. They do not replace the turn-by-turn map in the car.
