FlyerFly is an app for putting out yard signs and door hangers with your own crew. When your team puts out a sign, the app saves a GPS pin, a photo and the time, so you can see where every sign you placed is. While a job runs, your crew member's dot moves on your map with a Live badge, and a GPS trail shows where they went. It does not check whether a spot is legal, so use the rules above. It's nonpartisan and works the same for any campaign.
