Alex, on my iPhone 4 I have "Star Walk" and "Sky Safari Pro". Sky Safari comes in two cheaper versions if $40ish is considered excessive. Sky Safari runs on iPhone, iPad, Mac and Android. Sky Map probably better suits for the beginner.
I also have "Moon Globe", MoonMapPro, Sputnik (ISS/Iridium satellite predictions); a couple of Wolfram apps - "Stars" and "Planets" (but Planets won't run at the moment); and from NASA, "NASA", "NASA SWx", and "3D Sun".
"3D Sun" just sent a minor (Kp=5) geomagnetic storm alert.
Others will have more suggestions.
