The first audio guided tour of the Sky !
No knowledge in astronomy needed. Start the visit and open a window on the Universe.

This guided tour will lead you from Earth to the outbounds of our galaxy. Accompanied by an astronomer, you will travel through the Universe as if you were riding a ray of light.

Put away your bulky telescopes, this app creates for you the sky in real time : travel through the planets, the stars, our Sun or comets even at daytime, by moving your phone or tablet towards the sky and see the stars in 360° !

Our pinpointing function helps you to discern astral bodies in the sky that will illustrate the different steps of your trip. Under a clear sky, it will lead you to see a galaxy with naked eyes.

To become a new stargazer, monthly news will be displayed to show what's up in the sky.

Cosmos Story can be used worldwide.
For southern hemisphere users, it will display specific southern sky astral bodies.

Information describing the celestial objects does not appear properly in the window. Only the first sentence is visible.

The audio quality of the narrator needs to be uniform. He is alternately far from, near to; to the left, or to the right of the microphone.

He mentions the speed of light about 17 times (enough!). The description of the planets stops with Jupiter. No mention is made of either Uranis or Neptune. I was expecting a detailed look at each planet. I am especially interested in the moons of Saturn and Jupiter, but there is nothing like that at all.

What would otherwise be a beautiful guide to the night sky is cluttered with a clumsy moon-to-universe strip on the right hand side of the screen, and on the left, unclear icons that need to be redesigned. Do we really need an icon to turn off the app? The home button does that on every single app.

There's a lot of potential here, but sadly, it is very underwhelming in this iteration.

Love it!

Just the first minute alone is worth the few dollars spent on this app. Very informative and easy to understand for younger people as it is interesting for adults. Many features with real time viewing of your own sky.

Great journey, but no instant info

The audio tour of the night sky is great. One of the menu icons displays outlines of constellations, but not names. This would be a 5 star app if I could touch a constellation to get its name.
