What's New

Version 2.4.5

+The functionality of Time Machine has been drastically improved it’s become easier to jump to the desired date in the past or future to see the night sky then.
+Added the ability to set the exact coordinates. This makes the night sky map more precise as you can stargaze far away from the cities thus you can enter the coordinates instead of the nearest big city or current location.
+Improved onboarding instructions to introduce new users to the apps’ main features.
+Tune in star brightness while stargazing: switch off the stars that are not visible from your location to make the sky less crowded and make it easier to identify objects in the night sky.
+The search enhancements: the search has become more flexible.
+Added names of stars in constellations 3D view
+The NEW way to sort out stars according to the radius, distance, visual magnitude. Hundred thousands of stars are now easy to find according to their properties: the brightest, the biggest, the farthest.
+UI improvements connected with new fonts & colors.
+Multiple Bug fixes

Can’t even test it with the excessive ads


I want to try this app before I buy the full version, but seemingly every few seconds an add takes up the screen. I can’t even view the stars due to this. Please change this

- update:
The only apparent fix by the developer is “if you don’t like the ads pay for no ads”. Well, I actually want to see if it’s worth my money before I purchase an app, which is not possible with the excessive ads. The developer knows this problem, however they only care about your money, and not satisfaction. Please download other versions that are not money pits. I will change my review if I see this problem fixed.

Developer Response

Thank you for taking the time to write a review. The ads can be easily removed with no-ads or all-in-one bundle. Bundles are available in the Additional content section of the app. Have a nice day.



This is a great app, and perfect for astronomy without the fancy equipment. It does have inapp purchases, but it still works very well without them. It does have quite a bit of adds, but they're not popping up one after another. This is an overall amazing app and you can still use it during the day because obviously the stars are still there during the day.

Developer Response

We are so glad you enjoy our app. Thank you very much for the kind words!

Shooting Stars


Also, please add a feature where you can see the constellations back in like 1000 BC and also years from now!!! That would be awesome!

I love the app! Just one suggestion... can you add a feature where it shows when shooting stars are visible in the night sky? That would be most fun! And awesome!

Developer Response

Thanks so much for the review. You can observe the night sky in the past and in the future with the help of our "Time Machine" (upper right corner on the screen, the clock icon). As for shooting stars visible in the night sky, we have recently added "What's new" section where you can find alerts about upcoming astronomical events. Have a nice day and thanks for being with us!
