Are you struggling with pointing your antenna? We have two solutions for you. iSat (http://itunes.apple.com/es/app/isatapp/id406009646?mt=8), that offers your the possibility to calculate the azimuth and elevation for your antenna to point to a particular satellite. Using the built-in GPS or an Internet connection you will find yourself and with this data the application will calculate the data you need to get the signal from the desired satellite.
If your have a Dreambox or any other Enigma or Enigma2 based receiver, then your application is SatPro (http://itunes.apple.com/es/app/satpro/id435604684?mt=8). This application will give you the azimuth and elevation for your antenna (as the iSat) but it will allow you to connect to your satellite receiver and receive in real time the signal to noise ratio, this is a unique feature that will help you a lot. Also using the internal compass and inclinometer you will be able to see where exactly is pointing your antenna.
