On the iPod Touch and iPhone 3G, the image will change as you hold the device up in front of you, making it easy to match what you see on the screen to the real sky. Pinch the screen to zoom in to planets, and double-tap to zoom out.
Use the "Show Me" option to guide you from facing North to the object you are looking for - its never been easier to put a name to those lights in the sky, or check to see what the phase the Moon will be for the entire month. Use the built-in time machine to see what the sky will be like tomorrow, or quickly jump to nightfall. On cloudy nights, play the Constellation Quiz, with with or without helpful outlines. Youll soon be an expert skywatcher!
Pocket Universe is ideal for beginners, and works well with naked-eye vision, or as a guide when using a pair of binoculars.
