4 Sky Guide
Sky Guide, demoed during Apple’s fall announcement event, is a great way to bring the magic of space to your iPhone. Just point at the app at the sky, and Sky Guide will let you know exactly which celestial bodies are there in real-time — including constellations, planets and stars. Just tap on any of those sky-based objects, and the app will bring you to a page with more information. Sky Guide is $2.99 on the App Store. Get it here.
