I have a small construction company with a couple of sales people covering different areas of town where the best way seems to get more new work is basically just driving around, one area at the time. I am looking with an app that let's you remember the route, displayed on a Google map, so they don't spend time driving streets multiple times. Was really looking for something where you can drop a needle mark for locations they find as well. It seems like most GPS aps out there won't let you add on to the last "trip". Tried Runkeeper, Runmeter, GPS tracking HD, Waze and nothing so far. Thinking there would be something more geared for the business community maybe. Any ideas? Thx!
