I have been using Satellite AR for all of my aiming and it works great when I have 4G or wifi service. Coworker recently (finally) got himself an android smartphone, but his site surveys / installations take him out to extreme rural areas. Has anyone purchased the dishpointer "pro" app and what do you think of it? I have posted this on another site as well, so as to get a broad consensus as to how others feel about this app before purchasing it, or, if there are better / preferred applications available. thanks!
