Doesnt align with known sat maps

I give the developer full marks for developing a nice looking app. Unfortunately, for my application, the app doesnt cut it. I needed to align to the G-19 satellite and the location of the satellite changed depending on where I was in the yard. Where this app says the satellite is and where other satellite maps tell me it should be makes me question the accuracy of this app.

Please understand. I am not a professional installer nor have I tried to align more than one satellite dish. The one reason I bought this app for one reason and it could not help me...
