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.”

Too difficult to read


Maybe it’s a bad setting or something but I find the data in the app very hard to read. When I first got the app several years ago it was fine but it keeps getting “prettier” and less useful. For one thing, object labels are missing if they are near the edge of the screen. As you get them closer to the center their labels show up as an unreadable gray. Finally, when they are almost in the center they are in a tiny but somewhat readable white font. Why aren’t they white all the time? If you’re using the app to try and find something you have to center the thing first. That’s hard to do if you don’t know where it is. Another hard thing to see is the horizon. It’s very subtly darker than the sky. Why not make it better defined? The planets are hard to find too. The pretty icons on the map can help but the red text is too dark against the black background. Things near the galactic equator are hard because the Milky Way image is much too bright. Finally, the new moon is shown as black. OK, it really is but if you’re trying to find it, good luck. If you center where this invisible object is, of course, then you may be able to spot the tiny white label. It would hurt the prettiness, I guess, but I’d love to see a white outline on it. Finally, this is the slowest app I have when I start it. It has pretty little animations of its name for a good 10 seconds. I didn’t get it for that. Basically it sacrifices utility for aesthetics.

Thank you for taking the time to write a review. There are a plenty of objects shown on the screen at the same time, if all of them was labeled, you wouldn't be able to read anything. So the stars are not labeled unless selected, but planets, satellites, meteor showers and the Sun and the Moon are labeled permanently, except the case when a satellite goes 2/3 off the screen area. Planets (the Moon as well) can be easily spotted if follow the ecliptic or with the search option (the magnifier in the lower left corner of the screen). Your remarks on the fonts color and size are greatly appreciated and will be taken into consideration. The launch time depends on your hardware solution, on A9 and higher cpu it takes about 2 seconds, on A8 – about 5 seconds.

5yrs later and I still love this app

Rip Roaring Raft Guide

My favorite part is if you get to far out with no service (always the best stars) IT STILL WORKS! We camp for 2wks every summer up in the Big Horn Mountains in Wyoming and there is no hope of service until off of them, but this app is a camping party favorite EVERY year not to mention It is all I ever wanted growing up! As a teen I saved my mowing money for a cordless phone (pre-cellphone era) and would lay in our pasture for hours and hours all summer long with my glow in the dark constellation coffee table book and Gf on the phone, now I can just hold up my phone and know my stellar address, neighbors and man made junk, I will never look at the stars the same 10/10

Thank you for taking the time to share your positive experience with our app!

Love this app.


I wish I could afford a big fancy telescope to truly show me the detail of our night sky.. until then this app is helping me learn placement in time of the night sky around me and for that, I am thankful. I can look at a constellation, pick a star and learn all about it. I can also see satellites. I think this app is a wonderful learning tool for anyone interested in our galaxy and learning what's around you. Even if you have a telescope I think it would be a great asset to locate and identify what you are looking at. It is very informational.
