What would be the -rating of this review ( being the lowest and being the highest)? "Screen overlay detected error... Avoid apps that require screen overlays to be disabled. This is one of those apps. The problem is even if you disable all overlays this app often still complains that an overlay is detected. This is simply nothing more than bad programming. There are other astronomy apps out there that do not suffer from this limitation. In my case I could never get it to work on 2 out of 3 of my devices no matter what I tried. The only reason it works on the third device is because I did a factory reset then installed it. However because it pops up this error I uninstalled it from all my devices and I use another app instead."
