REDSHIFT

although the price may seem high for an iOS app, this is a full-featured astronomy program. as with many astronomy programs, you can view the annotated-night sky using the compass and gyroscope features of your iDevice. Redshift goes much further by allowing you to take a simulated flight out to the planets and objects in the solar system, and even to a vast number of stars around the visible universe. as a casual user, i found it very addictive, just jumping from one star to another to see what objects are within their views. there are lots of customization options to increase the amount of information displayed for more serious astronomy buffs, but im sure anyone would enjoy the ability to fly between the stars that Redshift offers.
