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

Awesome app to help locate stars. I have a dobsonian and it helps finding planets and deep sky objects. The paid version is pretty cheap and removes annoying ads. The only thing that I don't like is the settings don't seem to stick. I'm not a fan of the "auto zoom" setting. I have to turn it off every time I open the app. Happens on other phones so it's not an installation problem. What's the point I'm having settings if they reset every time?

Visuals are great, but it sends you these notifications that only show you partially about things that entice you, so then you tap on the app and there's no such information there. And at least in my case, I dig for it and can't find it anywhere. So it would get five stars if that was more easily accessed in an intuitive format, but it's great visuals and a fun way to find out what you're looking at, at least, and I do believe those are the primary functions anyway, so a solid 4 out of 5 stars.
