I loved this app when I 1st got it. I liked seeing where every constellation, planet locals, & meteor showers were; plus, the music is phenomenal! However, I've begun noticing that locations of many focal points are wrong. For example, I'll point my phone to the moon. I'll see it in the night sky with my eyes, but it's not shown on the screen of my phones app. There is an arrow on screen pointing to the moon; if I turn my phone to the right, it will find the moon, but it's faulty info

Last several months I have noticed that my location gets lost and I can't keep it from zooming in automatically. Pretty annoying. I loved it at first over the years. But it needs some serious fixes. At least once I adjust the settings every time I use it it still helps me know which stars and planets I am looking at. So that is good. Hopefully there will be updates soon to fix the issues.

Terrible performing app. It prompts you to calibrate your GPS but there is no way to do this. With the GPS off it just spins in circles. Any setting changes you make have to be redone every time you open the app. It will prompt you to an attraction with arrows but it will never actually locate what's available. Terrible app
