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.

This is my first app of this type. It is what I was hoping for, plus a little more. I like the way I can move the map manually and even more it tracks the movement of my phone. I also like the ability to move into a star, a cluster or a galaxy and see a lot of information about the object that I have zoomed into, plus, if the grid lines are enabled, the sense of that object moving through space is very apparent which really enhances the entire experience. Try it, you just might like it too!

After having been contacted by the developers, My initial complaint has been addressed. While I always felt this sky-mapping app was beautiful, I became quickly frustrated with not being able to use the phone gyroscope. This is now fixed as you just need to tap the compass icon below the screen, which I honestly never noticed in the past. I'll say it was an oversight, and not paying attention. Now, point, aim, and see parts of what you want to see in the sky on your screen effortlessly. A+

Hi. To activate sensors, press the compass button on bottom center of screen and point the back of device to sky and screen should move with device. Please also ensure that no magnet or metal are near the device, such as on device protection covers. If issues continue, please email us with details about your device so we can better check.

Edit- After trying the developers suggestions, the app was able to calibrate just fine. The app has some great features but every time I open it, it asks me to calibrate but it won't calibrate when I complete the required motions. The closest I got to a complete cal was 60%. The locations are therefore highly inaccurate when looking out at the sky.

Hello. Thank you for the feedback. For issues with calibration, please ensure that there are no magnet or metal pieces near the device as it can interfere with sensors and are usually found on device protection covers so please try removing the cover and re-calibrate (move device in all directions for 30s) Hope it helps.
