Pocket Universe

Have you ever looked up at the night sky, and wondered what exactly you were looking at? Pocket Universe is an easy-to-use app that will help you learn the names of constellations, bright stars, planets and more. You can literally hold up your iPhone, iPad or iPod Touch in front of you, and the app will use the built-in compass to display the same view of the sky you see - but one that's complete with names and information.

Then explore the Solar System, and take virtual walks on the surface of the Moon and Mars, before playing a game to help you learn more about astronomy that you thought possible.

Every night there is something to see: Pocket Universe will provide you a list of suggestions, as well as give you regularly updated news and observation tips - which you can even share with your friends.

You don’t need to be an expert to use Pocket Universe, and everything you see has a useful pop-up information window and links to Wikipedia for the latest information.

With over 80,000 stars, beautiful textures, built-in quiz games, updated news, lunar phases, information on the moons of Jupiter and Saturn, an Orrery view, and more, there’s so much to explore.

Key Features

Pocket Universe was the first iPhone astronomy app to support the built-in compass, and it was also the first to add a true augmented reality view using the iPhone's built-in camera! Use the camera view in the evening or morning sky to overlay the labelled view over the real sky.

Simply hold up your iPhone in front of you, and the view will be exactly what you see - but with names and information at your fingertips. Move the iPhone around to see the view change in real-time.

Easy-to-use astronomy application, which focuses on helping you answer the question "What's that in the sky?"

Fantastic !!!!

I’ve had this app from the beginning and it has always got better and better with each update. The AR feature is the best I’ve seen; the children blown away by the planet and solar system views. Well done all who have developed this.

Mars madness

Mars is currently magnitude -2.9 and yet on this app’s Sky page it’s a very pale, easily missable dot.

Virtual skys the limit!

Downloaded this not expecting too much. The "Virtual sky" mode just seemed too good to be true. Having tried it out I can honestly say that it works incredibly well (I have an iPhone 3gs with the built in compass).
Astronomy always interested me, but between work and family I just don't have the time to faff about with charts and maps etc. With the "Virtual sky" function you can find and name constellations and planets in moments with no messing about. I have a friend who paid thousands on an expensive telescope with motors and software to locate objects in the night sky, with this app I can do it for less than £2! An absolute bargain.
Only minor issue was that it is quite fiddly to click on objects to get the details, but a quick switch to manual positioning allows you to line up and see the astronomical data without too much hassle.
With this app you can maximise your time spent watching the sky, so even if you've only a few minutes to spare you can always find something interesting. You can even use the "Sky report" to tell you what you can see that evening, so you can check before you get off the sofa!
I am a complete beginner in Astronomy, but this app has whetted my apetite and I'll be in the garden most nights exploring the sky. A genuine five star app. Try it and you won't be dissapointed.
