This app is very useful – Is it dark outside? Review

When I was just a small fetus, I never was able to tell the difference between if it was dark, or not dark outside. This app has been life changing. Now if I want to know if it's dark outside all I have to do is whip out my phone and go into this app and boom, I know if it's dark outside. 10/10 would recommend!
