Sky Map

Sky Map is a hand-held planetarium for your Android device. Use it to identify stars, planets, nebulae and more.
Originally developed as Google Sky Map, it has now been donated and open sourced.

Troubleshooting/FAQThe Map doesn't move/points in the wrong placeMake sure you haven't switched into manual mode. Does your phone have a compass? If not, Sky Map cannot tell your orientation. Look it up here: http://www.gsmarena.com/

Try calibrating your compass by moving it in a figure of 8 motion or as described here https://www.youtube.com/watch?v=k1EPbAapaeI.Are there any magnets or metal nearby that might interfere with the compass? Try switching off "magnetic correction" (in settings) and see if that is more accurate.

Why is autolocation not supported for my phone?In Android 6 the way permissions work has changed. You need to enable the location permission setting for Sky Map as described here:https://support.google.com/googleplay/answer/6270602?p=app_permissons_m

The Map is jitteryTry adjusting the sensor speed and damping (in settings). We have a better solution coming soon!

Do I need an internet connection?No, but some functions (like entering your location manually) won't work without one. You'll have to use the GPS or enter a latitude and longitude instead.

Can I help test the latest features?Sure! Join our beta testing program and get the latest version.

Amazing, it was my first ever star map and all the others were far too complicated for me. Even now, years later, I use other more complex maps, but this is good when I just want a simple view on things. I do recall looking for some items and not being able to find them, but still, I HIGHLY recommend this app if you're new to star maps, find other star maps too complex or simply was a simpler more basic map too. Well done, I've got nothing to complain about 👌🏼

I tried this because Andscaloid took their Planetarium app of the Google store. Don't like it. It shows you the map yes, but Planetarium would show you where everything was in relation to your horizon and it had a thing that would help you find it by causing you to tilt your phone around to locate it and your phone would be pointing right at it. Instead of a whole overwhelming map of everything and trying to guess which is which.

Sky Map is excellent, a true revelation of the sky! Well done to all Devs. You have to make sure the compass is calibrated though to ensure accurate alignment. As well as the suggestions in the app, imagine rolling a ball around the screen to aid on the calibration (that's how my compass app does it anyway!). For me, the app always reports uncalibrated even when it is, although it reports accuracy as high. Could be my phone I guess? Anyway I love the app.

finally a device with all sensors & this app works, but... appears to be 1hr behind, some error, but it gets you pointed in the general direction; search darkens the image too much; declination & right ascension grid would be nice instead of celestial.

Ant. B. Mar 6, 2022     

Love this, no ads, accurate depending on your device and calibration, will remain on my devices for as long as it is around. Recommended to anyone else interested in looking up and out of there own small lives.

Not sure what the big black octagon is on the map, but it's great so far. Been using it for years, but reinstalled it to see the planetary alignment which isn't visible from this hemisphere. It would be nice if we could use this as a live wallpaper, then 5 stars. I know my 5th star will make you millions! 🤣

Love it! There's a red filter that preserves night vision. Easy to search for specific features or identify a celestial object you see just by holding the phone up to it.

Sco. B. Apr 27, 2022     

Had this app for years. The interface works well, but it is now wildly inaccurate, showing the position of the moon this morning, for example, some 135 degrees away from where it actually is in the sky, or the sun overhead when it is still below the horizon, despite manually correcting the date/time settings that were off by 7 hours somehow. Timing must be broken, and then some...

The app is generally well designed, but is completely unusable as the image constantly shakes and jitters, even after calibrating the compass and holding it perfectly still. Please fix this bug ❤

Mar. M. Jan 8, 2022     

The image jitters, no matter that the phone is steady and not hand held. So this shuddering makes it impossible to read the words on the screen. If this doesn't change soon, I will have to uninstall as it's not fit for purpose. Two stars merely because it has potential so I'm hoping the developers can fix this issue.

Cas. H. Jan 12, 2022     

Please add fast forward and reverse buttons without having to enter time and date (which should default to right now, btw). I often just want to see the way the sky will change from now until a few hours ahead.

Simple no-nonsense app that does what it is expected to do. Loads quickly and is always accurate. Highly recommended. A suggestion to display comets and meter showers if possible.

Joh. M. May 25, 2022     

The app isn't very helpful, and isn't always accurate, but the options available meet my needs. There are many different things you can pick from in the app.

Ron. H. Dec 6, 2021     

In the beginning, years ago this ap was spot on, very accurate. I've tried installing it on every new phone I get and as with the first install with my 1st smartphone after nearly a year it went bizerck and it's display went upside-down. With each new phone I've downloaded again to see if it would work as it did in the beginning. A complete failure each time! Of course I try to recalibrate it, but to no avail! It has always shown the constellations and star names, but never accurate!

Good app, but drains battery. I deleted before because of battery drain. I downloaded again to find out the three planets that were really bright next to the moon. Since downloading again I struggled to keep my phone charged and remembered why I deleted it before.

Ste. Jan 30, 2022     

Wonderful. Our phone's sensors can be scrambled easily as a heads up, the window in my room causes the view to spaz out. Try it in different areas.

Jul. B. Jan 21, 2022     

This was exactly what I was looking for. Straight forward, can search for anything Inc events on now, or where to look when they are on at any particular date or time. Simple to use and pretty precise, which depends on your device too. Gotta say I love it 5⭐

This is a very useful app to help locate stars. I have a few issues though, which I hope the developer can address. 1. Upon loading, it always focuses on the nadir, which makes no sense. Is there a way to get it to focus on the horizon by default? 2. I have to press the mode icon 3 times to get it to allow manual navigation. 3. Orientation. It only allows portrait view. Even when force horizontal is enabled, the text is still in vertical view. If these can be fixed, I'd give it 5* :)

I really like the way Sky map is set up, the options are great, but I have a confusing issue (solved). You were right, Sky map didn't know my lat and long, I played with the settings and it's right on point now, thank you for your help. The constellations seem to be rotated out of alignment. As an example, Cassiopeia should be almost directly over head given where I live and the time of year, but the app reports it on the Northeastern horizon instead, even when I use search.

Hei. S. Feb 20, 2019     

used to be my favorite app bit for some reason recently the calibration is totally off. my phone shows high accuracy and I have no issues with any other apps but everything is way off now. it's great to have all the constellations but when things aren't lined up it's kind of pointless. very disappointed with whatever it is they did to lose their accuracy.

Spo. M. Apr 5, 2021     

Really love this app. Works great on my Galaxy A51. One thing bothers me though.. the background is annoying. At night I want the whole background to be solid black. There is no option Ive found to turn off that black to blue hazy gradient thing that is permanently in the background. I can turn off everything else, stars, planets, etc. So why not let users turn off the annoying background coloring? Makes it less enjoyable to use in the dark. Please fix in the next version. Otherwise, its awesome

Very good, I love looking at this to find planets in the night sky. However I have always had trouble with the default mode because the map wouldn't move with my phone. I figured out that my phone doesn't have a gyro and I have a solution to others out there with the same issue. First, open the app, then once you're in the map, tap the three dots at the top right corner. then you click 'Sensor Settings' then you click 'disable Gyroscope' And it's that simple! Hope this helps.
