SKY TONIGHT is a brand-new astronomical app for exploring the sky. It helps stargazers answer the three most common questions:

⁕ What is that bright dot in the sky?
⁕ What astronomical events can I see tonight?
⁕ How can I find the object I'm interested in?

Made by the developers of Star Walk apps, Sky Tonight is a customizable stargazing tool, that is designed for users with different needs and wants. You can adjust the constellation's appearance, set a reminder for any space body configuration, explore the unique relative to observer trajectory, set up a magnitude limit to filter out space objects, and much more.


► Point your device at the sky to see the real-time positions of space objects on the interactive sky map.
► Activate the Time Machine and determine the position of celestial bodies at different time periods.
► Use the augmented reality mode and see the sky map overlaid on the image from your device's camera.
► Get extended information about any sky object by tapping on its name.
► Stay updated on the latest news from the world of astronomy with the What's new section.
► Turn on the night mode to make your sky observation in the nighttime more comfortable.
► Filter the objects that appear on the sky map according to their visual brightness.
► Regulate the brightness of objects on the sky map.
► Spot dozens of asterisms along with the official constellations.
► Adjust the visible constellations and customize their representation on the screen.


Instead of the classic trajectory that shows the object’s trajectory in the celestial sphere relative to the Earth’s center, the app presents the object’s trajectory in the sky relative to an observer. A long touch on the trajectories relative to the observer will move the sky object to the selected point. While holding the touch, move your finger along the trajectory to change the time.

Make use of the flexible search — quickly find space objects, easily navigate across different objects and events’ types. Look for "stars", "mars moons", "mars conjunctions", "solar eclipse", and the app will show you all related objects, events, and articles!
There are also Trending and Recent categories in the search section. The first one presents the currently most popular objects, events, or news; the second category contains objects you recently selected.

Set event reminders on any time and date not to miss a solar eclipse, a Full Moon, or a star-planet configuration you're interested in.

Check out the calendar of celestial events that includes lunar phases, meteor showers, eclipses, oppositions, conjunctions, and other exciting events. Learn what astronomy events will occur this month or see what happened in the sky a year ago!
Verify the Stargazing Index calculated from a Moon phase, light pollution, cloudiness, and time when an object is visible. The higher this index is, the better the observation conditions are.

You don’t need several apps for your stargazing planning anymore; Sky Tonight contains all the info you need.

Premium Access:

* The app includes paid Premium Access. Get Premium Access to use Sky Tonight with no limits! Without the subscription, you can’t see most of the interface items in various sections such as Visible Tonight, Calendar, and Search. Therefore, you’re limited in planning and improving your observations. Premium Access will allow you to unlock all the interface items in any view and make the most of all the app’s features. Advertisements will also be removed not to interrupt your stargazing experience.

Detailed and Thorough

this app is really amazing. the level of detail in each heavenly body is incredible! they have orbit trajectories, peaks in the horizon as a function of time, data about the stars and planets, size, distance, visual magnitude. It’s frankly overwhelming how detailed and well made this app is. On top of that, the augmented reality is extremely accurate and responsive and the constellations are artistic renditions that are fun and interesting while still allowing you to see the star formation and lines behind the art piece. just an incredible app overall and i recommend everyone download and just have fun with it for a few hours.

Have a wonderful day!

Pretty sweet.

Very nice touch to an evolving app but curious why I need to keep buying a new app instead of updating these features within star walk 1 and 2. A few suggestions- I wish the stargazing index would reference and show how it is being calculated, do you use CSC data? I would also love to see nebula or other DSO listed on the visible tonight list (as the settings ask for magnitude range I would love to see darker objects added). Add a setting to increase panning speed while searching, it’s too laggy. Don’t let these suggestions take away from the utility of this app. It’s been great, love the trajectory of selected objects with hourly tick marks! Makes it easy when I should go outside. Thanks!

Developer Response ,

Thanks for your ideas. We've already added DSO to the Visible Tonight list. Perhaps, your other suggestions will be also implemented in the future releases.

AWSOME so far

Actually just got the new app 😁
I didn’t things could get better than the star walk 2 App. But I’m sure it will be evan better! Love all the apps !! So enjoy full !! Love just sitting in my hot tub after finishing my swing shift in the city of Denver well … not so much Colorado any more!! More like calirado or colorless evan New Rado. With this and the other apps I can float away to another planet or star evan a whole new galaxy!!!
Thank you for all the serenity. And keep looking up 😇😉🤘. TTB.
