Creepy terms of service

Wow, just wow.

Great for Identifying Stars AND light pollution!

While this app is great for identifying the amount of light pollution where you live, I tend to use it more to just see where certain stars are in the sky, which is a great feature! Because of its dual abilities I give it 5 stars!

Clever Idea, and Helping the World!

ps I was forced to download this for school, but I tried it, and it’s actually pretty cool. The title explains my thoughts!

Inconsistent

Hello,

I did this one night, clearly saw some stars, barely saw some stars, and it said my limiting magnitude was around 5. The next night, after maybe a little more night vision adjusting, I could clearly see everything they threw at me, and it told me the same thing! Also, there should be another option. Some stars I can just see, like Regulus. Some stars I can barely see and need averted vision to see. Other stars, I need a little time to try and find, but once I find them I can see them. I put those as "clearly seeing" even though I kind of moderately see them.
