I have a Directv app on my Android. It has nothing to do with finding a signal. It's much like the Directv website where you can program your dvr to record a program, view the channel guide, pay your bill. That kind of stuff. Like others have said, Dishpointerpro is an app for Android and Iphones. It uses your phones camera to show you the location of the sats you need. You can select the sats you need in the menu. It overlays their position in the sky on your cameras screen to show if you have trees or whatever blockng the dish's view to the sats. It does show you the basic direction to point your dish. It does nothing to show signal and I don't know of any app that could(it would have to be plugged into the sat cable). We use the meter on our receiver to lock in our signal. Every "pro" installer we've talked to has said you can't align your dish without a signal meter(a $300-$400 separate meter). They not quite right. We, as well as others do it all the time, with no more weather dropouts as we get at our professionally insatlled system at home. It's really not a big deal. Like your sd setup, once you do it a few times it'll be a piece of cake. Just get a good solid tripod and PLUMB the mast. Go for it. Have fun.
