User Reviews

Users find Flicker Meter for Light - PWM to be a simple, focused tool that can help identify flickering rooms and is easy to use. When it works, it’s praised as effective and reasonably priced, and several reviewers noted that developer responsiveness improved performance. However, multiple reviews question the app’s reliability, especially with PWM-dimmed lights and higher-frequency flicker, where it may miss flicker or report steady output. A recurring pain point is the upfront paywall/ subscription requirement before trying the app. Overall, the app shows promise but remains inconsistent across conditions.
Pros
  • Simple, focused app that does one thing well and is easy to use.
  • Helps identify which rooms have flickering lights.
  • Generally useful and appears worth the price when it works.
  • Noted improvement after developer feedback; responsiveness.
Cons
  • Flicker detection is unreliable, especially for PWM-dimmed LEDs and higher-frequency flicker.
  • Gating by upfront subscription/in-app purchases; usability is hindered before you can test.
  • Does not consistently report flicker across use conditions, leading to questionable trust in the output.

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

Our lights flicker all the time, the power level problems here are related to the Benghazi like Data Center under construction. Surges and RF effects from Drones also affect the lights. People here have filed and won a Class Action suit for the Dirt related to this data center+- it’s likely another suit will follow RE: electronic smog destroying everything from appliances to Mental Health- that’s right, we feel the effects and it’s painful and it’s been noted in the medical record, people want out of this community- it’s toxic and hurts!

Listed as free on the app store, after using it once it would kick me out after declining to pay for a subscription. Useful for the one time i could open it
