I really hope someone can help me. before IOS 11, I was using an app that someone got me hooked on way back in late November 2012 called VisionHunt 2.6.1. I loved this app for detecting if lights in my hours were on or off. it never got updates, but it worked for what I needed so that was ok. now that apple changed things in IOS 11 where 32 bit apps no longer work, I can't use this app anymore, so I need a new one. the thing I liked about this app was that it was more than just detecting light sources. it was also a color detector, and it had a couple other things it could do too. I don't care if I have to pay for the app, so long as it does what I need it too, and it does as advertised.
