Duran Duran's keyboard Nick Rhodes mentions Star Walk as his favourite 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.

Developer Response ,

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.

Unhappyyyyyy and angry ,

Not very intuitive

I came across this app, recommended as an interactive astronomy guide when researching the auroras as one is currently visible in Southern Hemisphere. After paying for a subscription I’ve got access to the full app with comprehensive information on constellations and planets, and an events section. I was disappointed to not find any section of this app covering auroras or to not even see it in the calendar/events section. Additionally the UI is clunky and not simple to navigate through. Maybe this app is better suited for an experienced astronomy buff who gets the technical side and not someone like myself who is more at a beginners level.

This app is really interesting and you learn a lot about all the satellites. If an object is close enough you may even see it moving. When you search something in the search bar it will automatically take to the celestial body. So in other words..... THIS APP IS AWESOME!!!!!!!!!!!!!!!!!!!!

Developer Response ,

We are excited to receive such feedback. Thank you so much for the kind words!
