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

“Star Walk is the best stargazing application I have come across for the iPhone. Many of the features found within the application cannot be found in any others! This is one of the best developed and executed applications I have seen to hit the app store.” - iMore

“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.”

Just one tiny thing...

Love the app but a little thing... when there is a red flag indicating a message or notification you open up the app and .... nothing.
If you’ve got something to tell me, tell me. Please.

Response to developer: I guess I’ve got flags turned on but notifications turned off - so I see the flag but not the text of the notification. Thus the lonely flag leads me to expect something when I open the app.
It’s no big thing but when apps like mail and other messaging apps have the red flag they somehow show the relevant messages when you open the app. I was just expecting this to follow the ‘norm’. One of the great beauties of the Apple ecosystem is that things work - and different things work the same ... mostly. This just broke my with expectations.
This is not a major criticism - the app is still great.

Thank you for the feedback. Your remark is taken into consideration. We send ntifications to keep users up to date with the latest celestial events. It is assumed that you read the text of the notification and go to the app.

This app is extremely super user friendly. Top notifications, just shake your phone to realign, point at your area of curiosity in the sky to know what you're looking at.

This is an amazing app! I’ve been using it since I don’t even remember! More than 5 years, I think. It is hypnotizing! Colors, sounds, view and interface are perfect! Thank you for such a beautiful thing!
