About this app

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.


The Map doesn't move/points in the wrong place

Make 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 jittery

If you have a phone that lacks a gyro then some jitter is to be expected. Try adjusting the sensor speed and damping (in settings).

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. https://play.google.com/apps/testing/com.google.android.stardroid

Used to love this app. I've used it on multiple devices and Android versions for years. I've recommended this app countless times and have gotten good feedback from those who installed and used it. Unfortunately, it's no longer accurate. I mean, it's way off. I've recalibrated my Pixel 7 Pro running Android 14 to no avail. Tried to manually input my location to no avail. It will change the position of celestial bodies as I'm holding the phone still, in the exact same location. Edit-clarity

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.

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.

Glad you solved it Ryan. We probably need to work on the location code a bit and make it more obvious when we haven't successfully got hold of it. Android makes it harder to get the user's location these days (this is a Good Thing) - but sometimes it gets in the way of the user sharing it even when they want to.

What's new

Adds Comet Leonard, which will be visible for a few days around Christmas.

Sundry translation improvements and a major refactoring of the code.
