Thank you so much, Dilip! Really glad Flicker Meter is hitting the mark! Reviews like yours mean a lot to an indie developer!

Unclear that it actually works

I tested on every light in my house, LEDs and incandescent and used a tripod for stability. It said no flicker for every light but I know that isn’t true. I don’t know how I can trust the output - but I subscribed “for life” lol
