I put my business card on people's doors to advertise my services. The last couple years, I have been using Google maps and just "remembering" which streets I've been down. It doesn't work well as a system as you imagine. This coming spring though, I'm going to be ramping up my capacity for service and am going to go pretty hard and heavy on marketing in the spring.

Are there any apps for android, or in particular just for a PC that has the satellite view and zoom and all that, but I can also just mark off a chunk of a subdivison so I know it been tagged with cards?

I'm potentially going to have a worker run around and put cards on doors for a few weeks with/for me and I'd like to be able to coordinate with them so we can cover as much ground as possible. And I would hate to put cards on doors twice, not only a waste, but irritating to be spammed IRL like that at home.
