Whether you're in search of the constellation Virgo, the Andromeda Galaxy or the next big meteor shower, Sky Guide is jam-packed with information and rich graphics that will satisfy the most curious minds.

Absolutely brilliant

As a Year 10 student who is never really involved or interested with space or the universe, I have to admit that after buying and downloading this app I have become so much more interested in what’s out there. This app is absolutely brilliant, whether you are in your room or outside, it is interesting nevertheless. Firstly, it was absolutely breathtaking at the visuals, all the constellations are visible. I find the compass feature amazing, you are able to face any direction and it will show which stars are there at this exact moment.
This app also tells you when approximately the sun rises or reaches its peak, as well as other stars and planets too. Once you click on the star, it provides really interesting information to read and you’ll find yourself reading for hours and being intrigued.
News is also provided from the space station, and you are able to see upcoming comets and eclipses and when the moon will be full.
Every penny was worth spending on this app, and you can joy even without the secondary subscription. Definitely recommend if you are bored and looking for something to amaze you, or you’re just simply intrigued by our universe.

A Star is Born

Excellent response, visuals and customised instant info, in the light of day and night. Sheds light on even the darkest parts of the universe. Gob smacking accuracy in the timing of natural and human made space objects. Using the app to track the ISS rising from the equator, passing overhead on a clear night, then disappearing below the opposite horizon, is probably makes me feel ten years old again!
A slight irritation, which is probably my own fault, is that, even though It knows my location in the UK, I seem to get notifications as if in the USA. Open to suggestions about that.

Unforgettable times with my son

Going to bed with my then seven year old was always a challenge. He was and still is spinning in high freqency and it’s always hard to get to bed. Just one more game, one more story, one more, one more. I had the fscination of the stars and the universe from a very young age. Read and learnt whatever was available at the time. Following that passion I downloaded this app. One night instead of trying to order and beg my son into the bed I turned this app on and started looking out the window. He then asked me what it was. I explained him about Orion’s belt that was up that night. The giant star Betelgeuse. We kept track of Syrius the frosty star. That became our favorit star. Hope the others wont take offence. We moved from London where we were at that time but we still search for our stars. If we see them then all is good. Thanks for the opportunity that I could share the love of stars and that we can learn so much about them.


Space is big. See more of it.
