Im looking for a relatively simple iPad app here, I own a wireless ISP and we have 14 different towers, and when at a customer address I can use it to get an idea how far and where a tower is. Using probably google maps all I need it to do is be able to let me drop a pin on a map, and have a list of stored locations. I then can select a location and the iPad will point me at it using compass, and how far I am from it.. Sounds simple enough. Anyone know of one?
