Pros & Cons
Very high user rating (4.78) from a large user base (313,126 reviews).
Massive reach with over 10,000,000+ downloads and 760K in the last 30 days.
Real-time identification of stars, planets, constellations, comets and satellites by pointing your device.
Rich catalog of deep sky objects and 3D solar system rendering with cross-cultural constellation views.
In-app Stellarium Plus unlocks advanced features (magnitude 22 visibility) and most enhanced observing tools, which means some power-user features are behind a paywall.
Some marketing terms used by competitors (e.g., live/view/explore) are less emphasized here, which may affect perceived breadth of experiences compared to others.
The core experience is free, but advanced capabilities require the Stellarium Plus upgrade.

This astronomy application has an easy to use and minimalist user interface, that makes it one of the best astronomical applications for adults and children who want to explore the night sky.
Stellarium features:
★ View an accurate night sky simulation of stars and planets for any date, time and location.
★ Dive in a collection of many stars, nebulas, galaxies, star clusters and other deep sky objects.
★ Zoom on realistic Milky Way and Deep Sky Objects images.
★ Discover how people living in other regions of the planet see the stars by selecting the shapes and illustrations of the constellations for many sky cultures.
★ Track artificial satellites, including the International Space Station.
★ Simulate landscape and atmosphere with realistic sunrise, sunset and atmosphere refraction.
★ Discover 3D rendering of the major solar system planets and their satellites.
★ Observe the sky in night mode (red) to preserve your eyes adaptation to darkness.
Stellarium contains in-app purchases allowing to upgrade to Stellarium Plus. With this upgrade, the app will display objects as faint as magnitude 22 (versus magnitude 10 in the base version) and enable advanced observing features.
Stellarium Plus features (unlocked with in-app purchase):
★ Reach the limit of knowledge by diving in a massive collection of stars, nebulas, galaxies, star clusters and other deep sky objects: • All known stars: Gaia DR3 catalog of over 1.81 billion stars • All known planets, natural satellites and comets, and many other minor solar system objects (10k asteroids) • Most known deep sky objects: a combined catalog of over 2 million nebulas and galaxies
★ Zoom almost without limits on high resolution images of deep sky objects or planetary surfaces.
★ Observe in the field, even without internet connection, with a "reduced" set of data: 3 million stars, 2.3 million Deep Sky Objects, 10k asteroids.
★ Control your telescope through Bluetooth or WIFI: drive any GOTO telescope compatible with NexStar, SynScan or LX200 protocols.
★ Prepare your observing sessions using the advanced observation tools, to predict a celestial object observability and transit times.

This app is great this is the reason I started stargazing.
★★★★★Elina N· Jul 19, 2026
It's so amazing it's like having a telescope but on your phone. I chose to do the free trial and it's even better. The light pollution levels in my area are very high all the time (7-9 bottle daily) so I can look at the sky on my phone as if there's no light pollution. Very lovely app especially for astronomy nerds because you can learn about constellations and planets

You see something in the sky, you open the app, point your phone, and there you have it! Really good, even better with satellites and space junk.
