Best stargazing apps: AR apps and virtual star maps to help you navigate the night sky

Having one of the best stargazing apps installed on your phone is a great idea if you're interested in the night sky. These powerful tools have many uses, whether you're a novice skywatcher, a seasoned astronomer or an avid astrophotographer.

Every stargazing app is a little different in one way or another, with each app having unique features and tools. Generally, however, they're all helpful in learning about the night sky, pinpointing particular celestial objects or as a tool to help when setting up a telescope.

Now's a particularly good time to invest in one of the best stargazing apps, however: We're just a few weeks away from the total solar eclipse, which will be visible in North America on April 8. Where an app has specific features that will help in viewing the solar eclipse, you'll find it mentioned below. 

Stargazing apps can be helpful when setting up one of the best telescopes or the best telescopes for deep space and have offline functionality, which means you aren't reliant on the internet to keep them working in remote areas. They use the GPS on your phone to guide you, so you should be able to point your phone at the sky and get started.

For astrophotographers particularly, setting up one of the best cameras for astrophotography often means going off-grid to avoid light pollution. The best stargazing apps can help you to find your shot without weighing you down with unnecessary (and heavy) kit, as they run conveniently on a smartphone, so as long as you have your phone on you, you'll have access to their guidance.

You can put many of these apps to the test before committing to spending money (usually a one-time payment or subscription) as some of them offer free versions or free trials.

The best stargazing apps we recommend in 2023

Best stargazing app overall

Image 1 of 7

SkySafari 7 Pro is one of the more expensive stargazing apps on the market, but if you're serious about the night sky, it's well worth the asking price. As we discovered in our SkySafari 7 Pro review, this app is an absolute powerhouse. It provides details on millions of stars, galaxies and other space objects. The planetarium page syncs seamlessly with the night sky whatever way you're holding your phone and also offers an impressive AR overlay option via your phone's camera.

Furthermore, its latest update has made SkySafari 7 Pro ready for the total solar eclipse: You can use the app to find the best places to view the eclipse from, simulate the event before it happens, and know exactly what to expect beforehand. 

There's a wealth of features in the app, but one of the best for astrophotographers is the Observing Planner. You can use it to choose the type of celestial objects you'd like to observe (think galaxies, globular clusters or nebulas) then sort results by their location, to find the ones visible closest to where you are. 

We're also fans of the 'Tonight's Best' feature, which lists all the best viewable objects on a particular night. It's great for planning a shooting schedule, and very handy when viewing with a telescope, too.

Seasoned stargazers will appreciate SkySafari 7 Pro's ability to control Celestron StarSense telescopes via WiFi. The app also adds a social element to stargazing with OneSky, which shows you the most popular object currently being viewed by other users, and SkyCast, which lets you share your observations with another user.

Keep an eye on prices because you can sometimes get all these features for an even lower price than the previous SkySafari 6 Pro, as well as being treated to a slicker user interface and a greatly expanded database. The only thing to be aware of is that this app takes up a large amount of storage space on your device.

Best for astrophotographers

PhotoPills is a sophisticated stargazing app, calculator, map and celestial almanac rolled into one. It scored top marks in our PhotoPills app review and will be especially appealing to astrophotographers since it helps you to work out the date, time and the best shooting spot to capture your chosen celestial event. In addition to this, it can suggest an appropriate lens to use and calculate the optimal exposure and depth of field settings for your target object — awesome! 

PhotoPills is especially well-suited for astrophotography involving capturing celestial events behind specific landmarks. You can use the app to plan your shoot and find the perfect spot — capture the Milky Way rising over a mountain or the Andromeda Galaxy setting behind a castle. Once you have your shot, you can share it with the wider PhotoPills community.

If you're planning your total solar eclipse viewing, PhotoPills' built-in Planner will come in super-handy. Not only does it have a list of every solar (and lunar) eclipse between now and 2050, it allows you to view on a map where will be the best places to view. It's also capable of tracing the path of the solar eclipse over time.

That's just one of many excellent features of the app, though. The Planner can also be used to track the exact sightline, azimuth and altitude of the sun and moon — even better, you can overlay that information using the AR and Night AR modes on the sky in front of you. It's a fantastic feature when you're out on an astrophotography shoot.

If you're not an astrophotographer, many of the tools in Photopills may be overkill, but if you're serious about night sky photography and like the idea of being able to plan your shoots well in advance, this is a game-changing app.

Best for Apple users

Sorry, Android users, you'll have to sit this one out: Night Sky is a stargazing app designed especially for iOS. Along with working valiantly on your iPhone or iPad, there's also a new version of the app that works with Apple Vision Pro.

If you are an iPhone user, though, you'll find Night Sky to be a helpful and nifty stargazing app that packs in many of the features you'd expect. You can point your phone towards the sky to have it provide details about the stars, constellations and galaxies, for example, and it's bolstered by some very helpful AR features.

An 'information' icon next to any object of interest within the app can be tapped, and that will bring up a useful description of what you're looking at. You can make the most of the app by using its 360-degree function, which allows you to point your phone anywhere — even towards the ground —  and it'll display constellations that would be visible on the other side of the world.

We love that using Night Sky inside will project an overlay of the sky onto your ceiling. If you subscribe to the app's Plus version, you'll be able to make use of Planetary Portals, a tool that allows you to essentially "step through" a portal to view the night sky from a new perspective. Super cool.

Whilst much of this is available on the generous free tier, unlocking the full 1.7 billion star count and some of the more advanced features will require an upgrade to Night Sky +, though you can take advantage of a month-long trial before you commit.

Best for entertainment

We can't exactly describe the NASA app as a stargazing app, but if you're interested in the night sky, this is still an absolute must-have. Rather than a traditional stargazing assistant, the NASA app is an absolute treasure trove of information directly from NASA, filled with articles, videos, daily updates, podcasts, information and sighting opportunities.

The best thing? The NASA app is completely free. Not a single paywall in sight. So whether you've got just a passing interest in astronomy or an expert, it's well worth a download.

The app's interface is pretty intuitive, with all the information organized into several key categories. You can jump to content to watch for example, or see all latest articles with just one click. Hit the 'view' tab, and you'll see NASA's image of the day and astronomy picture of the day, which provides some seriously inspiring viewing.

With the total solar eclipse coming up, the NASA app unsurprisingly has some useful information. You'll find information about how to prepare for viewing, with events happening between now and the eclipse in early April. Doing a search will also bring up various press releases relating to the solar eclipse, so there's plenty of useful reading.

Kids will particularly enjoy the interactive elements of the app, which allow you to whizz around the Solar System and tap on different objects to learn more information about them. The app is also ideal if you're hoping to catch a glimpse of the ISS flying across the sky as you can set it to notify you five, 10 or 15 minutes ahead of when it's due to pass over your specific location. All in all, this free NASA app has plenty to spark the curiosity of children and adults alike and is a great download for space enthusiasts.

Best for realism

Stellarium originated as an open-source planetarium desktop program and the Stellarium Mobile Plus app was developed by the same creators. It contains an extremely comprehensive map based on the Gaia DR2 database, which includes over 1.69 billion stars and all known planets and comets from a catalog of over 2 million nebulas and galaxies. Few apps can come close to matching those numbers.

The app uses the GPS on your smartphone to display a map of the stars that are above you in real-time, and you can also link the app to your telescope via Bluetooth or WiFi, making it a great companion for serious astronomers. Whilst it doesn't give quite as detailed information on different objects as some other stargazing apps, it offers fantastic high-definition photos of the Moon, nebulas and galaxies that you can zoom in on.

Another fun feature on this app is the ability to move about in time. This means that you can fast forward to see what will be visible later in the night or select a particular date to view. In our Stellarium Mobile Plus review we found that this feature can get a bit buggy if overused, but it's still a neat function to have.

The app is reasonably priced, but if you're dead set on saving money then it's worth noting that the original desktop version does work on a mobile browser. However, it doesn't offer the same offline functionality as the app so it will be less useful in remote stargazing spots.

Best for beginners

Star Walk 2 is a great option for beginners who just want to dip their toe in and see what a stargazing app can do. The free version is generous, with occasional ads, and it only costs $5.99 to access all features including add-ons, which is relatively inexpensive for a stargazing app.

For that low price, the app packs in a lot of content. It has a database of over 200,000 stars, eight planets, 27 asteroids and comets and 10,000 satellites. In other words, pretty much everything you'd hope to find when gazing at the night sky. We particularly like how easy Star Walk 2 is to set up and use: simply point your phone in any direction and you'll be given information about what's currently visible in the night sky. There's also a neat AR function that will overlay various constellations, planets and satellites onto the sky above you.

Its 'Visible Tonight' function is helpful for astronomers or astrophotographers who like to plan their nights before heading out: It will show you which planets and constellations are due to make an appearance. The Celestial Event Calendar will let you see things ahead of time too, and it's there that you'll be able to track things like the total solar eclipse as we get closer to it happening.

Another feature we loved is the optional filters, which includes x-ray, gamma-ray, h-alpha, radio and microwave. This lets you view hidden aspects of space objects that would never normally be visible with the naked eye.

Although Sky Walk 2 lacks some of the sophisticated features offered by the likes of SkySafari 7 Pro, it is a much friendlier starting point for beginners and comes at a very affordable price.

Best for information

One of the least expensive stargazing apps, SkyView is well worth trying out. Its paid version will only set you back between $2 and $3, which is a great price for everything you get. On top of its cheap price, it's easy to set up and has some really great features, making it a doddle to locate particular stars and nebulas.

If you're wanting to use the app in a more built-up area or can't easily get away from light pollution, the app's option to increase or decrease the magnitude (brightness) of the stars will be a welcome addition. SkyView's interactive star map automatically recognizes objects and constellations, which you can then tap on to see close-up pictures and read detailed descriptions.

If you use a Space Navigator telescope or set of binoculars, you can also use it directly with the app and have it point you to particular objects. However, they're not the most popular brand, so unless you already happen to own one, it won't be the most useful feature — there's a reason they didn't make it into our lists of best telescopes and best binoculars.

The screen art and information are great, but we did find that it tended to disappear a bit too quickly with very slight movements of your phone away from the target object. We also found the AR screen to be a bit dark and harder to see at night-time. However, we loved having the ability to save interesting objects to make them easier to locate the next time you want to observe them, perhaps when you have your telescope to hand.

Despite having a few small drawbacks, SkyView is a straightforward and intuitive app that will be fun for beginners and kids who want to explore the night sky without having to spend a lot of money.

Best free app

If you're a newcomer to observing the night sky, Star Chart is one of the best stargazing apps that we can recommend. While there are add-ons available as in-app purchases, all the basic functions are free, making it a great place to start. 

Star Chart makes use of your phone's GPS functionality to tell you what can be seen in the night sky above you, drawing on information from its library of 120,000 stars and 88 constellations. You can tap on any one of those stars to find out more information about it, such as its brightness, its co-ordinates and its distance. It's the sort of information that's seriously handy to have if you're trying to line up a telescope. 

If you want to opt for the paid upgrades, you can find out information about meteor showers, dwarf planets, comets, satellites and planetary moons. 

Star Chart is useful for planning your stargazing sessions in advance or for catching up on events in the sky that you may have missed. The in-built calendar displays different activities happening in the sky each day, like showing you when the peaks of meteor showers will occur, or reminding you of the upcoming solar eclipse.

In our Star Chart review, we especially loved the Time Shift feature, which allows you to shift backwards and forwards in time to view past and future celestial events. Covering a span of 10,000 years, this makes it easy to track interesting patterns across time.

Whilst the features on offer aren't as sophisticated as apps like SkySafari, the user interface is much simpler and easier to use, so it's perfect for beginners. And since you can try it out for free, we see no reason not to recommend Sky Chart.

Best for AR

Sky Tonight is another app from Vito Technology, the same company who brought us Star Walk 2, and it is great for gathering lots of interesting information in one place alongside visually pleasing AR effects.

From the map homepage you can move your phone around to identify bright points in the sky as you're viewing them. When you zoom in and tap on them, it will bring up information about the stars and planets such as their history, lore and when they'll be visible over the horizon in the next month. With planets, you can track their path through the sky and see what position they'll be in on certain dates.

It's definitely a reading-heavy app, so you'll probably want to explore most of its information when you're back home. Make a note of what you've seen, and you can use Sky Tonight's search function to look them up and read about them from the comfort of the nice, warm sofa. 

Sky Tonight can be very handy when it comes to planning your next adventure, too. You can see a list of what's going to be visible in your area on any given day, and you can set reminders for big events like the solar eclipse, or even a random star-planet configuration you have an interest in. We also loved the app's 'stargazing index', which pulls together sunset time, moon phase and likely cloud cover into a percentage score of how likely you are to see anything on a given night — a very useful feature!

You can try out Sky Tonight for free, but to unlock extra features and remove ads you'll need to pay up to $8.99 for lifetime access. We think this is worth it for the sheer volume of information you get from the Sky Tonight app.
