About Star Walk 2

Star Walk 2 is a starguide, skymap and night-sky reference app that uses augmented reality (AR) to make its use as easy, intuitive, and informative as possible for astronomers of all levels.  It covers constellations, stars, planets and satellites, and helps users find them in the night sky and learn about them.

Star Walk 2 free is available on iOS and Android and is suitable for any student with an interest in the night sky.  It is a free download that shows advertisements while a single payment can unlock the full content and remove the ads.

Teacher Review

Star Walk 2 uses location tracking and your phone's gyroscope to show you what's in the sky using augmented reality. Point your phone up to see which stars, planets, and constellations are floating above you. Point your phone downward to see what's in the night sky on the other side of the planet. When you tap a star, you can read up on on more details and check out a 3D model of the celestial body. If you check out the Live Sky feature, you can see what time the sun and moon will rise and set and the current elevation of our closest planets.

What we love about Star Walk 2

Star Walk 2 app looks gorgeous. It is hard to imagine a starguide app looking any better. As you point your device at the night sky, the app uses AR to illustrate the night sky being viewed by the user. It also enhances it with fantastic depictions of the mythological figures behind the constellation's names.

The app also works as a news source for those interested in astronomy. It pushes details of celestial events to its device's notifications or through its What's New section. In addition, the app includes detailed information on the history and mythology of the various constellations, stars and planets, as well as a coordinates viewer for easy reference. A Time Machine slider lets you view the skies of the past or the future, and you can tap on individual objects for more details. A night mode allows you to stargaze without burning out your night vision, and an augmented reality view overlays the star chart over your camera view.

What skills does it improve?

Star Walk 2 app is focused on the night sky. While physical skymaps have helped astronomers identify stars for centuries, they have limitations that Star Walk 2 does not.  

Whereas a physical starmap shows a snapshot of the night sky from a fixed location at a specific time, Star Walk 2 adapts its starmap to the user's location and to the current time. This makes it much easier for users to find celestial objects, especially when the night is not fully clear. Students can be confident of what they have identified and begin to commit the night sky to memory.

For the most part, Star Walk 2 is concerned only with the natural aspect of space. It does cover locating artificial satellites but it is not the app students need for learning about human exploration of space.

The full version of the Star Walk 2 application also covers the Greek myths and legends behind the constellations. As classical history is a popular topic for children to cover at school, this gives the app a useful cross-curricular utility between science and history.

What age is it appropriate for?

Star Walk 2 is not targeted at any particular age. Both adults and children who are interested in the night sky can learn from it and use its tools.  

There is a specific section, unlocked through a full unlock purchase or alone for a lower price, that provides informative cartoons for children to learn about space objects.

Is Star Walk 2 easy to use?

Star Walk has an intuitive interface and, with just a little familiarisation, using it should become second nature. The advertisements in the free version can be frustrating and interrupt the flow, but this should only be seen as a trial and not the best way to use the app.

How will students benefit?

Beginners to astronomy have a lot to learn before the interest brings rewards. Star Walk 2 app eases the early steps by making identifying what the user is seeing so much easier than it would be with printed guides or any other format that is not an AR star app.

By making the learning easier, students can make bigger strides earlier on. They will know what they are viewing, either with the naked eye or with a telescope.

Star Walk 2 also lets students continue learning when it is daytime or the sky is less than clear. They might not be able to see the stars at a given time but the app can illuminate a skymap to let the interest continue to build. The extra detail about the objects in space provides interesting information and is a useful jumping-off point for further reading and learning.

How will teachers benefit?

The practical aspects of astronomy are not easy things for daytime-bound schools to teach. Using Star Walk 2, teachers can show students what they can see that night and explain to them how to follow easily spotted formations to find harder to identify stars.
The time travel features of the app are also useful to show how the celestial objects move in space and how scientists of the past have analysed them to discover the facts and challenge existing beliefs about the universe.  

How will parents benefit?

Parents may not have the interest in astronomy that their children have developed and so feel unable to help them take it further. Star Walk 2 will help them to nurture this interest and let them share it with their child.
There is plenty that can be seen in the night sky without telescopes or binoculars. Just this app and a few nights in the garden can be both fun and educational for all members of the family.

What Star Walk 2 can improve on?

The advertisements in the free version are so intrusive they might put people off. This would be a pity as, once they are removed, the app is excellent. 

How much does Star Walk 2 cost?

There is a variety of payment options for Star Walk 2 in the form of in-app purchases.

What is included with the free version vs. paid?

The Star Walk 2 free app is ad-supported. The ads dominate the app in this form making it clear that the developers intend for this to be used only as a trial.  

The price to remove the ads and unlock all of the additional content, covering kids content, planets, satellites and more is very reasonable and is a single one-off purchase rather than a subscription. Use the free Star Walk 2 app to see if it is what you want and imagine how it would be without the ads.

There are other, smaller, purchases that can be made but it makes the most financial sense to use the single 'unlock everything' in-app purchase.

Is Star Walk 2 safe to use

As with any app that contains advertisements, it is not possible to predict what advertisements might appear in the future. During this Star Walk 2 app review process, no advertisements appeared that could be considered unsuitable for children.

In terms of Star Walk 2 app's own content, it is entirely safe for children of all ages. Parents and teachers must, of course, ensure that children know how to stay safe as they view the night sky.

Overall rating of the app

Star Walk 2 app is designed for practical use when viewing the night sky but it is still full of potential in the home and classroom.

This is an excellent AR star app with a useful and full-featured starguide and skymap. The advertisements are an issue but the price to remove them is fair. The 4 stars awarded in this Star Walk 2 app review, take into account the intrusiveness of the ads but accept that it is only meant to be a trial version. Pay the fair upgrade price to unlock a five-star app.

Star Walk 2 is a next-generation tool for not only learning the exact position of stars, planets, constellations, comets, ISS, satellites, star clusters, nebulae and meteor showers in the night sky but also for investigating its’ depth like watching constellations, nebulae and satellites from aside.

Star Walk 2 is an exquisite stargazing tool that combines astronomical data with premium technology to deliver an effortless journey through thousands of stars, comets, and constellations. All you have to do is point your iPhone or iPad at the sky.


All-new stunning design:

  • New simpler and cleaner interface in vibrant colors for retina displays
  • Atmospheric visual and sound effects, stirring soundtrack
  • Exclusive handcrafted artwork for constellations, inspired by minimalist low-poly art

Incredible 3D models of celestial bodies*:

  • Planetary nebulae
  • Constellations
  • Dwarf planets, comets, and asteroids
  • Man-made satellites
  • Layer by layer planets and missions

Star Walk 2 is the first astronomy guide to introduce plausible three-dimensional models of planetary nebulae. Star groupings of the 88 officially recognized constellations are also presented in volume. You can see them as separate entities, turn them around and take a look from the other side. Complemented by articles on connected myths and history, this is the most comprehensive collection of information on constellations.*

As you hold your phone up and point it towards the sky, Star Walk 2 follows your motions using the built-in gyroscope to match the map on your screen to the stars seen from your location. Easily find any star, constellation, or satellite in the sky by tapping Search. Star Walk will indicate the direction to look in.

Unlike on a plain photograph, every star in Star Walk 2 has coordinates. That means you can look at objects, for instance, a constellation from any vantage point in space, not to mention the ultimate accuracy of your map for your exact location.

Star Walk 2 gives you accurate daily data on current moon phase, time of sunset and sunrise, and elevation of planets. With just one slide you can see how the sky will look later tonight or throughout the year.

Special night-time soft red mode will help you preserve night vision when stargazing with a telescope. You can see the sky in X-Ray (and 5 more filters) to study the invisible structure of the universe. Live tracking for over 8,000 satellites will help you catch iridium flares, and detailed articles will satisfy the most curious inquirer.
