- Stargazing Index: Get a personalized observation forecast based on the Moon phase, light pollution, cloud cover, and object visibility times.
- Flexible Search: Look up anything in seconds — search for “planets,” “Venus conjunctions,” or “solar eclipse,” and the app will show related objects, events, and articles.
- Extended Information: Tap on any space object to learn fascinating details about it.
- Latest News: Stay informed with real-time updates from the world of astronomy.
- Curve Generator: Instantly create a solar analemma and plot curves for the Sun, Moon, planets, asteroids, and comets. What once took months for astrophotographers can now be done in just a few taps!

With Sky Tonight, you don’t need multiple apps — everything you need for stargazing is in one place!
Note: The app is free to download, with an optional subscription to remove ads and blur in the extended app's object lists. Without a subscription, all objects remain accessible, but they must be searched manually.
Sky Tonight vs Star Walk 2: choose what suits you best
Sky Tonight has a minimalistic design, yet is packed with powerful tools like photo editing, an advanced sky view, a flexible search, and an extended celestial database. Star Walk 2, on the other hand, stands out with its visually immersive 3D models, along with the unique Planet Walk feature, which lets you track multiple planets at once. Learn more about the differences between Star Walk 2 and Sky Tonight on the dedicated page and choose the app that best suits your needs!

For many people, their knowledge of constellations, planets, and galaxies starts with the Moon and ends with the North Star. If you’re curious about what else shines in the night sky, try the Sky Tonight app for Android and iOS. Just point your phone at the sky, and the app will instantly identify celestial objects and reveal what’s out there. The built-in astronomy calendar helps you plan your stargazing sessions, highlighting major events such as solar eclipses or meteor showers like the Perseids. You can even set reminders for specific events, so you won't miss or sleep through astronomical highlights again!
This app is great for a real-world view of the night sky from your own backyard. As well as an augmented reality overlay of the night sky map on your surroundings using the iPhone’s camera Sky Tonight’s “interactive trajectory” tells you the exact path through the night sky of any specific object.
When we are observing in the real world, trees and buildings often get in the way. Cue this well-designed new app’s ‘interactive trajectory’ feature, which will show you the precise movement of a selected object, relative to where you are, for the rest of the night. It’s a powerful addition that, when combined with the app’s ‘AR’ (Augmented Reality) mode, will overlay the sky map on the surroundings using a smartphone’s camera.
Sky Tonight is an impressive app for anyone looking to explore the night sky. With premium access, you get an ad-free experience and unlimited features.
Sky Tonight can be very handy when it comes to planning your next adventure. 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 eclipses, 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!
Sky Tonight is customizable according to a specific user’s needs and wants. The user can adjust the constellation’s appearance, set a reminder for celestial object’s configuration, explore the observer trajectory, set up a magnitude limit to filter out space objects and so on.
Another very interesting aspect of this app is the Visible Tonight section, which will tell you what celestial objects you can see tonight. In addition, it will also indicate the level of visibility based on factors such as cloud coverage and light pollution.
I truly appreciate the sleek design and user-friendly interface of the app. Sky Tonight's standout feature lets me identify stars and view constellations by simply pointing my phone at the sky, which I find fantastic! It also offers concise updates on astronomical events and a wealth of information. As a keen astrophotographer, I find this app to be exactly what I need.
Sky Tonight is nicely designed while also providing a lot of great information. It includes augmented reality of the constellations but also the latest news in astronomy, a calendar of celestial events (including a daily stargazing index and weather), and a list of objects that are visible tonight (i.e. planets, constellations, stars) through binoculars, a telescope or using the naked eye.
