New in version 2.0:
• Eclipse Timetable
• Orbits of celestial objects
• Expanded database with 6500 cities worldwide, including 2500 cities in the United States

Which star is this? Where do I find Mars? Is it the ISS up there? Hold your smartphone or tablet up to the sky and see which planets, stars, or constellations are above you.

Where is Jupiter and how can I find my zodiac in the sky? The Sky shows you the position of celestial objects in the sky with just a few taps. Get close-up views not only of near-Earth planets and moons, but also experience deep-space objects in stunning detail.

What do the Saturnian moons look like? The Sky takes you on a breath-taking journey into the infinite realms of outer space. Fly to planets, stars, and other celestial bodies and let the app tell you about our Universe.

What is a solar eclipse and what does an opposition of Mars mean? The Sky answers your questions with stunning animations and insightful explanations. Thus, even beginners will be able to understand the mechanics and to visually imagine the most important celestial events.

No matter if you are a beginner or amateur astronomer, child or adult - with the intuitive app The Sky, everyone will immediately understand the sky - without much prior knowledge and long training.

Shine with your knowledge of the sky, around the campfire or on night walks: with The Sky, astronomy will always be a pleasure! Discover the joy of watching the skies and the age-old fascination with space that has inspired mankind for millennia – and become part of the worldwide Redshift community.
The app contains more than 9,000 stars, 88 constellations, hundreds of moons, asteroids and comets, as well as 200 spectacular deep-sky objects - all with accurate position calculation and motion tracking in real time.

At a glance:
• Recognize the stars and constellations of the night sky
• Identify planets, moons, comets, and satellites and track their paths
• Take breath-taking flights through space to distant stars and colorful nebulae
• See what’s going on in the sky tonight with a direct simulation of the events

• Information on how to safely observe a solar eclipse
• Eclipse timetable with the exact times for your location or best viewing position

• Sky map with the planets and stars that could be seen during the totality phase
• Illustrated explanations of how a solar eclipse occurs
• Everything about solar eclipses: Explanations and facts, illustrated with pictures and videos

Comments on The Sky by Redshift for Android

★★★★★ Slavoljub “Sasha” Krishan · Sep 20, 2025
Useful for studying the great comets! However, update functionality for comets, eclipses, etc. don't work!? Please help!
★★★★★ aequitas veritas · Nov 29, 2023
Snappy and charming astronomy app. Works well with simplified yet effective interface all around. However, the landscape overlay image filled with totally absurd artificial buildings or unrelated stuff isn't very proper. Pls let me remove it. I just want the universe and nothing about any cumbersome additives. If you need to add something as the background then pls let us apply the camera view to it (AR).
★★★★★ Jacquelyn Nalls · Mar 29, 2025
My husband & I love astronomy and watching the night sky. This app does a great job of providing real-time access and information. The virtual rocket fly by feature is my favorite! I would like to see more information included for all the celestial bodies that are included in your database, some simply provide a redirect you to Wikipedia.
★★☆☆☆ A · Jan 2, 2025
So I actually like this app, however It keeps shutting off after 3 seconds. I've tried reinstalling, but the same thing keeps happening. Help. In south alabama looking at the planets at night. There is a red one but looks to big for Mars, and I think it's the wrong time of the year for that one. So jupiter. Give me a fix.
★☆☆☆☆ Graham Smith · Dec 12, 2023
If you are thinking of trying a free app for night sky viewing, skip this one. They constantly pop super bright ads in your face ruining the night sky experience. Try a different free app.
★☆☆☆☆ Megan Hymers · Feb 10, 2025
Update won't allow app to stay open. Why did I pay to use this app if it doesn't work anymore?!
