Star Walk is the most beautiful stargazing app you’ve ever seen on a mobile device. It will become your go-to interactive astro guide to the night sky, following your every movement in real-time and allowing you to explore over 200, 000 celestial bodies with extensive information about stars and constellations that you find.

Get started quickly

• Launch the app and point your iPhone at the night sky, you'll see the stars, planets, satellites, and constellations in their proper place from your location. As you move your device, the star map updates in real time. The Moon is the easiest first target.

• Tap Augmented Reality icon in the upper right corner to add the image from your camera to your sky view.

• Use Night Mode to go easy on your eyes and preserve night vision when exploring the Universe.

Go deeper and beyond

• Every object you tap has an (i) next to its name, tap it to access information.

• A scale on right is the Time Machine, slide it to explore the map of the night sky of tomorrow or years ago.

• A calendar of celestial events will make sure you never miss anything interesting.

• TelRad will help you find the exact position of an object when stargazing with a telescope.

Share your experience

• Project to a big screen with no picture quality loss. Star Walk is your personal planetarium.

• Explore stunning space pictures in Picture of the Day.

• There is an entire stargazing twitter community within Star Walk - don't miss out!

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

"With the Star Walk app, if you hold your iPod up towards the sky, you can see all the stars and constellations. It even tells you the names of all the planets. Then, if you point it towards the ground, it shows you what all the stars are in the other hemisphere. 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."

    My students can really see into space. Pat, Nature Center Educator

  • This app is why you should own an iPad

    by rgsslo

    If you have any interest in astronomy or have children, this app is a must. It's cool to look at a constellation and see a satellite going through it. Can't go wrong.

  • My Fav!

    by Notau

    This has been one of my favorite apps for a couple of years. It's simply fascinating :)

  • Fun

    by ray m

    Fun and informative

  • Best app EVER



  • Never review...but.....

    by Sandy9265

    This is such an easy and fun app to learn science. I love all the bits of information that I get. I love the live sky indicating our sunrise and sunset and the same from other planets. I love this and I highly recommend it....

  • Love it

    by Acadian Proud

    Have used it a number of times to look up things.

  • Great App!

    by Erhie

    I've got a few astronomy apps on my iPad. I'm very impressed with Star Walk the most. I've also got Starry Night Enthusiast on my PC, which I paid $79 for. This app does everything it does, it's easier to use, especially outdoors on an iPad, and it's was 1/10 the cost.

  • One Pretty App.

    by Rdorro118

    I use this application all the time. When I was growing up I would see stars and constellations and just have to wonder what they were. Now I know. Works great!

  • Best over all app

    by Aleechis

    When I first this app I was totally amazed! I am still enjoying opening this everyday and learning so much. All of the details are informative and beautiful photographs. Love it!

  • One of the best

    by MS Reza

    You just have to work with this cool stargazing app, many photo, many details and most important, many useful information. Thank vito...!

  • Wonderful app!

    by Utexican

    This app helps one easily see and experience the imagination of those that gazed into the night skies many, many years ago.

  • Stellar app!

    by kindness factor

    My family loves this app! We take it on every camp out, enjoy it in our own yard, and often take it along as a late night learning activity at scout outings. The graphics are amazing and everyone from young to old can appreciate its genius.

  • Super app

    by Flatnsassy

    This is such a pleasure! I love walking my dog and looking at the stars; it's such a big help identifying constellations and individual planets/stars!

  • Still the best astronomy app.

    by jd2020

    So much information, so little dark sky! New apps may come and go but Star Walk continues to be the best astronomy sky app. It makes me wish I lived in the country where I could get a better look at the stars.

  • Star walk

    by Teapotnut

    I love this app.! Just wish I knew which area of the sky the planets rise and set. It gives the elevation but I don't know what that means. Frustrated.

  • Best Astronomy App!

    by SoloAviator

    This is the one to own. Truly the best at helping me understand what I am looking at in the night sky.

  • An Amazing Adventure into Astronomy

    by Bomanizer

    This is a tool that will allow me to introduce and enjoy Astronomy with my grand children.

  • Beautiful and Educational

    by TKBuckley

    I think I need a little faster processor and more bandwidth! Excellent presentation! Thanks for the gallery of images and especially the "fly through" videos. That's a great feature for an already excellent app.

  • A Joy To Use

    by bbp40

    I wish I had this app when I was a kid, I would have gotten a lot more use out of my telescope. This app has given me hours of fun and I learn new things all the time. There is something incredible about lifting my ipad up to the sky and have an incredible map of it appear live. I've noticed new features added recently that I've yet to check out fully but I would still recommend this app before even seeing new features.

  • Star Walk is the best

    by The bamaden

    I've learned a great deal from this informative app and it has the best detail - Thanks!

  • Awesome app

    by DaveinTn

  • The Best App

    by candelsjr

    This is by far the best science app ever!!!!!!!!!

  • My favorite stargazing app

    by JMC52

    When I want to de-stress I pull this app out and either just stargaze or impress people with my knowledge of astronomy. I really can forget the time looking thru the picture of the day. A truly out of this world app

  • Favorite App

    by vishalv

    I loved this app from the start and no other star gazing app compares, even several years after its release.

  • Wow!!!

    by BearinatorBear

    One of the most detailed and educational apps that I've used! Very complete. Very well made. You can spend hours getting lost in the universe in the comfort of your own home. I love seeing where the sun is below me at night! Not only showing constellations, details about specific stars/planets, and being able to point at the sky for information, but also showing satellites in real time! All I can say is "Wow!"

  • Fantastic experience

    by My favorite RSS reader

    Good for people to comprehend basic information. Most stars on this app, probably I cannot get their in my entire life. But I can also get excited during this app experience. Thanks

  • Great app packed with a tremendous amount of info!

    by Alseed101

    Great pics also

  • Pretty cool

    by Ca IDE an

    This app is pretty cool it has a calendar when cool astronomical things are happening, it show you where things are right now. By pointing the camera at a the sun or moon it calculate where things are like satellites planets and stars. You can zoom in on planet and nebulas and galaxies and it tell you about them.

  • Amazing

    by Grammy 1

    I originally got the Star Walk for my iPhone through SBux - and it has been the best app ever. Wherever I go the universe is available for me to find or figure out " what's that" in the sky. Now that I have an iPad Star Walk was purchased for an even better window to the sky's 5 Stars!!

  • Nice app

    by vfaler

    Nice app for stargazers and night owls.


    by PiMpEr T McDaniel

    I am a new into astronomy and was looking for a better answer for finding my way around the vast sky. I was using paper star charts and a atlas wheel but I was never content with it or really got a complete hang of it " though I had only tried using it for a week or so". I got the idea of using an app for the job instead and started to look at what was available. Star walk HD was in my opinion going to be my best bet so I down loaded it and I could not possibly be happier. The app has everything I could have wanted and more.

  • Starry night

    by Bhdujmmtmhif,

    This is one of the best app you can get.

  • Stunning

    by Thoughtly Put

    Just a wonderful app. Such great visuals and so much information. Most impressive!

  • Still one of the best

    by SJeanBenson

    This is still one of the best apps I've had on my iPad after all this time. I got my iPad in May 2011 and got this app shortly afterwards. My family and I ave used the app more times than its needed to be updated and still enjoy it. And yes, it is that useful to us. Enjoy it yourself or don't, but give it a shot and see what you think. So far it hasn't given me any problems and has been fairly useful.

  • Terrific App

    by cpeachbent

    Terrific App! A great resource.

  • Use Star Walk a lot!

    by Mark Grosz

    I use Star Walk quite a bit as it helps me easily locate targets in the night sky. Recently, I started using binoculars to view Messier objects. Star Walk helps me to plan and then star hop to the object. It's cool to zoom in while you are viewing the sky. The zoom feature helps you to become very familiar with the area of the sky you are searching. I also like to find interesting targets in Star Walk and then see if I can find them in the sky.

  • Fantastic app

    by seanlutz

    I use this app all the time when I star gaze at night. I love how it shows me events that are going to happen and where to look. Just a idea but could the galactic center be added. Other then that, this is a fantastic app!

  • Awesome!!!

    by Tkeeth

    So interesting.

  • Worth it!

    by For the Sake of Humanity

    Gorgeous, informative, and detailed. Make time and be fascinated again and again. With my limited knowledge haven't found anything that needs improvement yet but there are lots of great feedback out there. Plus, any electronic media that makes you want to look at the universe with your naked eyes is amazing, don't you think?

  • Love it!!!

    by Fantasma0010

    I love this app,had the previous version but this is the best so far.

  • Star Walk places the entire night sky right in your hands.

    by Law Bat

    The quality of this app is second to none. It is incredibly detailed, yet surprisingly user friendly. Star Walk is a must have for stargazers of any level of experience.

  • Clouds or not

    by SD Old Dude

    You'll love spending a lot more time looking up and learning. Even better when you take this out at night, away from city lights. Prepare to be amazed. Showed it off in the desert and everyone bought the app right there. Thanks!

  • Awesome

    by Evanm2007

    Simply awesome!

  • Amazing

    by ex2bot

    Take your device out on a warm, clear night and point this up at the sky.

  • Great app

    by Manic3

    This thing is amazing fun. The kids have learned lots observing the stars with this. I really like this app and consider it essential.

  • Star Walk Rocks

    by QQQQTOO

    Excellent app. Fascinating & informative. This is why the iPad was created, and why I have one. Definite 'wow' factor for everyone who sees it.

  • Great app!!

    by jhurt$

    This is my preferred to work with my telescope, highly reccomended!!

  • Words from a tenured user,

    by Criss 1020

    I use this app almost every night, I've written a review before and today I curiously scrolled around to look for it for the sake of quenching curiosity. Yet to my great dismay I am disheartened to see that it seems as though can't find it. As with all things unanswered, maybe it's the result of either conducting an inconclusive search, a server glitch, a bad connection or (lightheartedly) an act of God. I mean not to offend anyone with my very last result of reason, if you do not believe or understand the existence of a god (creator), then that's ok, I still love you and respect your beliefs or lack of them. Either way the point I want to convey is that words truly don't do justice to the awesome feeling I get every time I get the humbling experience to gaze and study the night sky. This app is in a lots of way and invaluable/"priceless" tool for me when it comes to identifying the lights in the night sky. Now, in reference to the title of this review, I would like to honestly point out that I have had and used this app for years. First on myiPhone and now on an iPad. As always my advice with this is and any other app, is to first go online and read and watch reviews before purchasing, lest you become a victim of buyers a regret. A feeling I'm almost certainly sure that many of you can join me, in unfortunately knowing all to well. I practice, hope, and above all wish for all mankind to share, love and be kind to not only one another, but also to all types and forms of life. May we become ambassadors or peace and love throughout the earth and cosmos. I am a scientist but I'm also a being who dreams and lives to make dream become reality, whether it be in my lifetime or in the far future. The pursuit of passionate work is in many ways, its own reward. Thanks for reading and it hope you find/reach or at least continue to pursue the answers and goals you seek my friend.

  • Star walking

    by UBNuttz

    Easily best app for my viewing ,easy,understandable ,beautiful. This is one app worth a couple hard earned dollars. Really n e 1 who is interested in stargazing should have this. Simple.

  • Very useful

    by NotToWorry

    I especially appreciate the ability to see the night sky from any place on earth at any date in history. This is a great asset to my 19th, 20th, & 21st century human history research into reports of mysterious light sightings. As you can imagine knowing what celestial lights were visible on any given night is invaluable.

  • Fantastic app!

    by David Andrade

    I get lost in for hours. Just wish I could play the music in the background too:)

  • Best astronomy app around

    by Bill the Turtle

    Best astronomy app around. Very helpful in discovering and locating celestial bodies in the night sky.

  • Amazing app.

    by Capflyboy05

    I love this app so much. I take it out in the field with me and my telescope. It has the whole Messier Catalogue, the stars, planets, galaxies, etc, in the correct locations. The only gripes I have are that this app is missing a pretty good chunk of the NGC list. That is the only reason I have to give it 4*. If you could add the rest, that would be amazing.

  • Love it!

    by Nowwut

    How can you not??!!?

  • Beautiful

    by dukester

    I love this app. I'm lucky to live in an area of Hawaii that is ideal for stargazing and Star Walk has made it all the more enjoyable and educational

  • Best of them all

    by 'ol Nick

    I have several astronomy apps and Starwalk is the easiest and most straight forward to use. Crushing through time and watching how the heavens change gives complete new insight into astronomy.

  • Great app!

    by S.S.09

    Really like it!

  • Awesome program

    by Tangquistador

    This app is awesome. if there is only one app that you can squeeze onto you device...this is's totally worth the the money and if i had to i would pay again for an update!

  • Fantastic

    by Jlmsoftball11

    This is the most awesome app. It's out of this world!!!

  • Night Mode Issue

    by kosmopolitisch

    The app is very practical. I am able to quickly locate celestial objects without the hassle of thumbing through a star atlas. The night mode is essential. Night vision is preserved through the use of red lighting. THE ONLY PROBLEM IS... if you click on a particular object in night mode, the information pops up using normal lighting. This defeats the night mode feature. I suspect that this is a minor fix.

  • Excellent tool for exploring the sky

    by Sonofableep

    I have been using this app for a couple years and find it to be excellent. The app is intuitive, full of information, and awakens the imagination each time I use it. The night sky becomes a world in itself, and my ipad is the lens through which I explore it.

  • T H I S I S T H E A P P !

    by Mackgeezer

    If you are looking for THE ONE APP to have on your iPad: this is the one to get. Five stars is not enough.

  • Charge twice, not cool

    by My_mistake

    The developers charges twice for the ipad version and the iphone version. Not cool at all. Should have gone for Sky guide instead

  • Amazing

    by I'm so major!

    I love this app. I just point my ipad or iPhone to the sky wherever I am and it shows me in real time what's up there in better detail. In the city I might only see a few stars but when I point my ipad or phone to the stars it shows you all the things you can't see due to city lights. It's like being in a planetarium only it's the real thing.

  • Great for learning all the planets

    by Bugsy2007

    I learn a lot on this app I learn all the constellations, planets, and other space stuff.

  • Support

    by Oneshot1212n

    Great support. Love the background music. Very engaging and mesmerizing.

  • Absolutely incredible!

    by Inkbrand

    Love this app. I will be learning from it for a long time to come. So comprehensive!

  • Best stars app

    by Hefasto

  • Most Excellent!!!

    by Tivojo

    A star gazer's must have!

  • Incredible! Get this now.

    by HMTR7086

    This is the best star gazing app ever. The graphics are incredible. We'll worth the cost.

  • Very impressed

    by PonyNoser

    Visuals are mesmerizing and educational. The music is engrossing. A great experience!

  • Mr.

    by TohioAst

    Hours of enjoyment! Luv the upgrades!!!

  • Star Walk App

    by StargazrVernNM

    Great app, I love to use it to see where the ISS is in the night sky and tracking follow it when it comes into view. Is there a possibility of adding Comets to the app? With the possibility of Comet Pannstars and Comet ISON being great in 2013 and the show that Comet Lemmon is currently putting on having that capability to be on the Star Walk App would be great. Plus having past comets like Halleys and Hale-Bopp. Thank you for your time. Thanks for updating current comets, hope you continue.

  • Best start app by FAR

    by Math person, pi guy.

    I love how easy it is to use, I can look up satellites, stars, meteor showers and more. It looks great, fit for iOS 7. My favorite feature is definitely the calendar, it alerts me when a meteor shower is coming. If you are looking for a start app, GET THIS ONE!

  • Amazing

    by Djkruczek

    This is THE best sky app I have. The information,pictures and sky images are great. Easy to use.... Just point, click and spend the next few hours enjoying the night sky. This is a " must have " app.

  • WOW!

    by hodgie4

    If you are amazed by the sky, this is a must have! You install the app and go outside and turn your iPhone or iPad to the sky and be ready to spend hours staring up in to the heavens. This is more addicting than Facebook!!!

  • Love it

    by $ky021

    One of the best educational apps. Defiantly the best astronomy app! + the solar walk

  • Star struck by star walk

    by Calamitykev

    By far the best astronomy app I have. I bought this one and another, this one is the best. there is so much info, beautiful pics. A planetarium in my iPad with soft music and all. Well worth the few dollars I paid for it.enjoy!

    by Shawna Arvizo

    This app has really helped me realize how impressive our universe is. It's so beautiful, and easy to use. Many different features, and loads of information. Simply a wonderful app ❤

  • Comet ISON

    by For you to be a success

    May as well that ISON ever existed. Biggest celestial event, customized just for this app. Tried to show it off, but it, in no way, was close to correct. No one attempted correct the problem. SHAME! Less than 1 Star.

  • Absolutely brilliant

    by Dogsbody67

    Starlight, star bright, first star I see tonight. No more mistaking incoming planes for Mars! The info, the presentation all are exceptional and a great companion to the night sky. Thanks star people!

  • Avoid it

    by Gifts blogs

  • Love It

    by NYGourmet

    Downloaded before camping trip. Worked great. Really got kids into astronomy. Getting telescope from Orion and I am sure this app is going to help us tons

  • Star Walk


    Using on iPad 1, v. 5.1.1., occasional crashes. Also, location of Comet Ison is seriously off. This morning the comet is in Libra low at sunrise but Star Walk shows it high in Virgo.

  • Awesome!!

    by Flyguy70

    The best!

  • Awesome, if only it would calibrate!

    by Longbow331

    I love the idea, but wish it would calibrate to my exact location. North is not true north with the app, etc....!

  • Love this app, but...

    by Chip Jordan

    When the app is working, it's a lot of fun. Unfortunately, it crashes at least 1-3 times each time I use it. Ipad mini, iOS7

  • Fantastic app for stargazing.

    by foodservicepilot

    I've had this app since it first came out and i still love to use it. Perfect for taking outside at night and stargazing.

  • Nice App but...

    by LosAngeles90631

    External "Apple TV" link does not work.

  • Best App!

    by Scaphinotus

    This is an absolute necessity for anyone who has been frustrated with using books to 'read' the night sky. For full appreciation of this App, take it camping with you away from the light pollution.
