★★★★★ Works well, it seems. Tested on Philips wake-up lamp, massive flickering. Hue light strips? Nothing. PC screen? Nada. OLED? Yep.

★★★★★ Hello 😊, dear developers 😊, thank you very much for your beautiful app. Flicker meter is indeed a very useful application! This app is very important for those who want to save their eyesight. I bought one of the latest smartphones, and didn't know why I had so extreme eyestrain :(, thanks to Flicker Meter I found out such a thing known as PWM (pulse width modulation). This PWM is extremely bad for eyes 👀. I recommend everyone to test every display with Flicker Meter before using!

★★★★★ Works, was able to detect that a LED strip was flickering a lot. Fixed by adding 10000uF capacitor on driver output side. According to app flickering decreased from 97% to 38%. And the eye strain I could previously feel when observing the light was gone. And now I know to avoid that brand of led drivers. Useful for detecting flickering beyond what the eye can perceive, above 60hz or so.

★★☆☆☆ 1. App is listed as free, and it's only free for 2 weeks after which requires license fee. Developer responded to my previous rating and comment by adding note about "a few weeks" trial period ("a few" == 2?) and keeping app listed as free. 2. Whatever the developer did after responding to me, my rating and comment disappeared :shrug: reposting with update here 2. After developer response it's still not clear why calibration is required - it's rather poor quality.

★★☆☆☆ Sadly the frequency measurements are completely off and inconsistent. A defective LED light which flickers with visible 50hz is shown as having either 200 (Xiaomi 11 ultra) or 270hz (Samsung A13). Other lights are for example measured with 150 Hz on Xiaomi and 200hz on the Samsung phone. Nice idea, bad implementation. At least, it can kind of reliability detect flicker at all, that is why I give two instead of one star.
