“Star Walk is a remarkably in-depth and detailed astronomy app. There's so much you can do with this app” - Common sense media

“This app brings the old paper star chart into the smartphone age, and makes exploring the night sky easily accessible to everyone.” - Soggy Astronomer

Duran Duran's keyboard Nick Rhodes mentions Star Walk as his favorite app:

“It’s brilliant, and if you’re ever somewhere with a clear sky and no light pollution, it’s a revelation. It’s beautifully designed and makes clever use of the available technology. I’m fascinated by astronomy, but even if you’re not, give this a go.”

Display of night sky

Names of stars and other objects too small, faint and insignificant . VERY DISAPPOINTED with present version compared with past one(s) which I would have rated 5 stars.

Developer Response ,

The size of the names has not been changed for a long time. If you have problems with the app, please, feel free to contact us at

Love it

Really incredible, almost as good as an observatory- worth the money.

Someone please help me with this app - from New Zealand

Three Star Rating ***

I am using this on my 4G Ipod Touch

If someone could help me with this app I would happily change my rating.

When I view the 'Sky Live' it says that the sun rises at 7:01pm and sets at 7:09am. Obviously this is not correct....

I also cannot seem to locate objects in the sky and overlay them on my ipod. When I see the moon in my sky, I try use the touch screen on the ipod to navigate to the moon, but the moon is under the part it moves in and does not show anything in my sky.

I am wondering if I live in New Zealand if somehow it has become muddled? Could someone please help? :)

Developer Response ,

Thank you very much for taking the time to write a review. The issue you mentioned has been fixed with the following updates of the app. You can use Star Walk anywhere in the world. Have a​ nice day!
