Comments on Sound meter : SPL & dB meter for Android

★★★★★ Charles Redstreake · May 23, 2026
This thing works perfectly. Ads aren't bad at all. Does exactly what it says it does.
★★★★★ michael w · Apr 27, 2026
A great app for free ! Easy to use. Useful settings for weighting and response. Recommended.
★★★★☆ Kevin Rains · Apr 15, 2026
It seems to work fine. I don't have a high-end decibel meter to compare it too, but I used to use a several thousand dollars decibel meter for work and the levels on the app seem to match sound levels for things I have used the expensive ones. I brought the decibel meter I used at work home and tested my lawnmower and air compressor. Sound meter matches closely with the expensive dedicated decibel meter.I had written the readings down in a notebook that I still have.
★☆☆☆☆ Kimberly Matthews · May 2, 2026
Please help! I just downloaded the app and paid for no ads when opening the app there is no settings button anywhere or a home page! Please help
★☆☆☆☆ IGOR666 · May 4, 2026
Too many legitimate vendor tracking toggles to switch off
★☆☆☆☆ Jeremy T · May 5, 2026
Meter is way off. I have a confirmed meter next to me and wanted to download this as a portable one. Almost 14 off.
