This is a neat app if you’re a science buff. Night Sky enables you to identify the stars, planets, galaxies, constellations and even satellites in the sky. Just stand anywhere and hold your iPhone or iPad up to the sky and Night Sky will display the names of the stars and planets.
Even if your view is obscured by clouds or daylight, Night Sky will know which stars, planets, galaxies, constellations and satellites are hiding from your view. It works better on the iPad due to the screen size but an iPhone still gives great results.
Night Sky is $0.99 at the App Store.
