United StatesDiffuser Missing - Annoying Pop Up
I haven’t been able to use the app even once with the “Diffuser Missing” pop up. Why can’t I make it stop? What if I am not looking for super high accuracy? I just need an approximate idea? Pretty tideous to do all this work to just run an app. The fact that I would need create or buy an equipment and that I will to buy their app should be mentioned.
United StatesA Gimmick
All I know is downloading the app and trying to use it really stinks. They almost force you to get the paid version. Trying to use the free version of the app is practically impossible to do. All you can do is turn it on and turn it off, nothing else. It’s OK, in a year or two Apple will have a Light Meter app built into their iPhones.
United StatesUtterly useless
You get about five seconds of use before you’re blocked by ads to buy features with no way to bypass. Look elsewhere.
United StatesDiffuser was an extra step but it worked.
Says you need a diffuser and stops working immediately BUT it is a simple thing to add. Just means you have to have it with you whenever you want to use the app.

United StatesIncessant pop up for diffuser
I’ve paid for the app, so I’d expect the pop-up for the diffuser to stop. I’d love to give the app 5-stars, but this is just so annoying and makes it unbearable to use. Please fix.
