Solid app but not worth paying for. I upgraded so I could try and see when I could observe the green comet by using the future looking time feature. First off, app isn't even showing or tracking where the comet is, which feels odd. Secondly, the point in time feature is wildly frustrating. It is not intuitive, and is either buggy or you are unable to hold the sky at one moment in time. I had to force quit as the sky was spinning out of control. Nice app though for the basics.

Not sure how so many people say this is the best star-gazing app they have ever tired. Then they say they love the music, so maybe that explains it. I've tried them all extensively, and this one is the most unintuitive mess of them all. Even after turning off all the nonsense that is on by default, the grid doesn't even have a basic North, East, South, West on it to confirm any sort of orientation. Believe me, there are much, much better options available on Android.

I enjoy the outlines of the constellations. The guides to the featured stars and planet is are very very helpful. Most times the compass is off, often by 90 degrees. Don't like that. It's helpful for night sky gazing. Just wish the compass worked better or that I could calibrate it. I live in the northern U.S.
