Ear damage
In it self the app works great and is very accurate. I compared it with a proper light meter and the results were the same. BUT - there is a huge bug. Every time the app is used while having headphones on the app makes a HUGE, UNBEARABLE shriek noise that is killing your ears. It’s so bad my ear hurt a lot afterwards. Be careful and NEVER use this app while having headphones on! If the bug would be fixed I’d give it 5 stars
