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.

Great app, easy to use. Wish it had the capability to go farther into the past than 4999 BC. Would like to see that on the website as well for my research. Also would like to be able to just type the date I want to look at on the website instead of trying to go backwards one year at a time. Would like know what start date is used to calculate from going forward or backwards or if it's based on current star positions, etc. I would like to be able to alter this setting if not current positions.

Awesome app! Works offline, too! GPS and real time, plus past and future results. No ads. Search for a star, neighboring galaxies, the moon, etc. and it will point you in the right direction every time. You can turn off the atmosphere, so you can see more during the day, and even at night. Highly recommend app. One of my favorites.

I have bought the paid version and I am quite pleased with the performance and accuracy of the app. I am very new to astronomy as such, but finding items I read about in the news and podcasts is pretty cool. The only thing I can take issue with is the names of the events or sky items are always different from the identity names used in the app. And I think that is the news media's problem, not the apps. Besides I just do a little more research and learn a lot more about what I am looking for.

I love this app! Definitely better than other 'star map' type apps. The free version isn't too limiting, and the premium version is extremely cheap. Very easy to use, and the fast forward feature is pretty useful to plan ahead on certain days if you're going out to stargaze. Nearly every star has a detailed explanation, which is really fun to use.

I find Stellarium very useful. I had some difficulty figuring out a number of the features, so I would have appreciated documentation. I would also like a few additional features: 1-some way to return to real-time when I get lost and it appears frozen. 2-some way to measure the degrees between 2 objects. 3-some way to force it to recalibrate when I notice it is not tracking any more 4-documentation to explain how best to hold the phone for the fastest recalibration. I highly recommend it.

it's an amazing app, I use it pretty much every night. I did upgrade to the paid. version but tbh it's not much different than the free one. I love learning so the in depth is descriptions are awesome! figuring out the different tools and settins is confusing but tips are plentiful on google. My favorite feature is the calander, it lists upcoming astronomic event's and also lists when satellites are passing by each night and let's you track them.
