Flicker Meter for Light - PWM

I was able to figure out which rooms had flickering lights and which didn’t. The app properly detected the rooms I was suspect of flickering, having seen them flicker in slow motion videos. Great app!

After my initial non-positive review, the developer contacted me and put a lot of work into improving the app’s performance on my iPhone Mini 13. The new version is much more useful. Measuring flicker seems to be a hard problem because use conditions matter a lot, but within that limitation I can now say the app does what I had hoped. Four stars for performance, five stars for developer responsiveness.

This is a simple app that does one thing well. It’s easy to use and understand. I’d love to be able to see the sine wave in a separate window, if the developer wants to add that feature in the future. Handy, simply, and one of the few currently available apps that read flicker. Well worth the price.
