About this app

Stellarium Mobile - Star Map is a planetarium app that shows exactly what you see when you look up at the stars.

Identify stars, constellations, planets, comets, satellites (such as the ISS), and other deep sky objects in real time in the sky above you in just a few seconds, just by pointing the phone at the sky!

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 Mobile 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 Mobile 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 8 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 DR2 catalog of over 1.69 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: 2 million stars, 2 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.

Stellarium Mobile - Star Map is made by the original creator of Stellarium, the well known open source planetarium and one of the best astronomy applications on Desktop PC.

My only complaint is that sometimes controls are a little janky. When I'm trying to swipe up to switch to a diff app on my phone for ex, it will just scroll up on info sheet for whatever object I've selected; or sometimes it will randomly go into phone mobile sensor view, when I'm trying to scroll around in manual control view, & I don't know how to get it to switch back, other than to restart app. But these are minor annoyances, not enough to take off a star. I love it greatly otherwise. <3

I love this app, I find it very interesting, educational, and fun. Sometimes it is hard to keep what you're seeing still on the screen. There is a pop up to calibrate your device but it never seems to work for me. I also had this app on an old phone and when I switched to my current phone I couldn't recover any of my data, since there is no way to create an account in the app. I am unsure if you can create an account to save your data if you purchase the premium version. Overall love the app :)

This used to work great for me, however, not so much anymore. It's always saying to do the figure 8 to configure, but as soon as I start moving my phone, it goes away. Currently, it's 8:20am and daylight outside, but Stellarium is showing it as being night time. It's just become inaccurate and unreliable.

Hi. If the app doesn't ask you to calibrate the compass it means that it considers it as decently calibrated. In any case, you can always make the 8 motion figure at any time (as long as sensors are enabled) to improve calibration: it's a continuous calibration. For accuracy, please also ensure that date/time and location is properly set in the app
