Maps, but no topo map?

I downloaded this app yesterday and hiked in the neighboring forest along a high ridge (yes, new user). Tracking was great and accuracy was fine. However, plotting my track on a "blank" map of the national forest land is pretty useless to me, as I would use this app for tracking progress on a mtn bike ride, hiking, or backpacking. Perhaps there is a topo feature (i.e. terrain view in real time) that I cant locate. Any ideas?
