Whatever application you use be aware that it's only as good as the maps.
I use the OpenStreetMaps to navigate around the UK and every once in a while someone has loaded a path on it that is marked as being suitable for cyclists but it turns out to be two inches of water on top of six inches of mud. I'm not sure what kind of cyclist they had in mind, that's more than I'd be willing to attempt and with that much mud it's not as if you'd want to walk through either.
Google Street View is good, and for all you need to check over a proposed route I do find the routing at
www.bikeroutetoaster.com to be generally good, even if only as a baseline that you can subsequently adjust.
