Hello all. As a new "casual courier", i am finding myself on a different route almost everyday that i am unfamiliar with. Does anyone know of a iphone app that you can put all your addresses in, and it spits out the most efficent order to do them in? Or any other advice to make my day less stressful? When I am out there, I am literally running from truck to door and back to save time so my productivity number is acceptable. There has got to be a easier way to handle a unfamiliar route.
