Is there a good app for long distance secondary roads?

Bacil, that looks like a great app! IIUC, it is more for close up stuff?

actually it does good in long and short distances, i have first time tested in mojave desert and with downloaded maps i managed to traverse whole NP on secondary roads with turn by turn (with some missed turns i have to add).

It has some camping grounds and hiking trails as well so for me its the one that i use in great outdoors.
