Oh, sorry i misunderstood, you want something that will actually tell you where to turn?
not sure such a thing exists, unless you can carry a satnav with you?
as far as i know the only thing you can do with a running app (endomondo or runkeeper) is check the map as you go having selected a route to make sure you are not straying too far from the intended path.
I have done this on my phone before.
