Get a notification when the sun sets. Waiting for full moon? Get notified when it occurs. Watch the movements of the sun, moon, planets, real-time -- or change the time.

Point your iPhone to the sky and explore the movement of the sun, moon, planets and stars across the sky while you change time by swiping the display. You can even change your location -- wondering how the sky looks where there's midnight sun? Or try setting your location to the other side of the equator and watch the sky rotating in the opposite direction.
