Controls can be a little unintuitive at first but overall I think this is a very nice app. Wish the stars would shimmer (like suggested in the loading screen) and the watermark was just slightly smaller when hiding the UI. Also the clock can be hidden via workaround (bottom right menu has to be open, then hide the UI from top left) so that works for me. I intend to use this app with a projector for ambiance at home, possibly also for education (just at home, nothing commercial). Worth 5/5.

I am not an expert but for an average user, the plusses are: sky objects are shown with nice realistic images, and we can see them from a 3rd point projection, not necessarily as sky view. However to my experience other features like the timer can be found in free apps too (skymap). Also, in this one I found the classification a bit poor, in skymap I can see the constellations, galaxies, meteorites seperately. Here they are all under "constellations".

Hi Dila, you can contact us at support@cosmic-watch.com, maybe we can then better discuss what you mean. I think reviews aren't here to compare with other apps.
