Astronomer makes browsing the stars fun. With multi-touch to pan, zoom, and spin around in the sky, Astronomer knows where you are and shows you the stars as you see them. Takes advantage of the iPhone and iPod Touch's gravity sensor, so as you tilt your device up and down, Astronomer pans the display for you. You can also search for the named stars & planets.
In response to the reviews, I have lowered the price from $4.99 to $1.99.
