About this app

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.

Sky Tonight features:

► 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.

Unique features:

Interactive trajectories relative to an observer
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.

Flexible search
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.

Fully customizable event reminders
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.

Astronomy calendar with a stargazing index and weather forecast
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.

I only wish the verbal information presented had more meat to every bite. Some have interest(s) in more profound explanations and are able to absorb it too, so, go ahead, let us try it on to see if it fits. Otherwise, it's fun and often very useful. Thank you for the concentrated effort to educate in one small app.

My favorite star app. I love that you can click on the stars and learn more info on the spot, love that you can adjust the brightness, and I even love the camera mode. I wish there was a way to turn it off and on more easier (the central button in the corner is confusing with that LOL) but otherwise this app is amazing. You can even follow the time track of any celestial body to see at what point in the sky it will be in (x) hours. I could go on forever!! LOVE this app!!! <33

I LOVE this app so much! I've used Star Walk 2 for over 6 years, and this app is amazing I love the cloud cover, light pollution, and the custom reminders! Premium access is so inexpensive compared to similar apps (I paid as soon as I got this app.), and the only weird thing I found is the daylight savings time transition, but that has nothing to do with the amazing quality! I am so excited to see what you will add in future updates!!!
