Is it a star or Saturn? Learning what's in your night sky is now effortless with Sky Guide. Hold your iPhone or iPad up and Sky Guide automatically aligns itself to the stars above you -- no setup or Wi-Fi required! Sky Guide is now available for Apple Watch. See a calendar of upcoming astronomical events -- the full moon, meteor showers, eclipses, and more. And it will even alert you when the International space Station is due to fly over -- and let you tweet one of its astronauts.
