The Sygic Caravan app presumably does all this. I found the interface difficult to manage, and the cost excessive for the use I would get out of it. As you might tell from the name, it's European, and there is a bit of culture friction. I believe it does do downloaded maps, which are really handy when you are traveling through areas with poor or no cell service (like SW Texas, which was totally dead to T-Mobile from Uvalde to Van Horn).

I think the RV Life app was written to do these things as well, though I haven't tried it.
