I've yet to see this for free or cheap. Good hunting. This is only so you can research this deeper as without the proper name, you may be hunting for a long time.
I am looking for an app from Google play that I can enter all my clients addresses that I have to visit in a particular day. I want the app to tell me which location to start with and then list the rest in order to make the day go by smoother. I don't visit the same clients often so it's not the same routes every time.
