About this app

Want to measure sound level? This is smart sound level meter app for Android!
Our decibel meter uses your built-in microphone to measure sound volume in decibels (dB) and also displays samples on graph.

NOTE: Microphones in most devices are aligned to human voice and the maximum values are limited by the hardware. Very loud sounds (~90 dB and more) may not be recognized. Automatic gain control used in some devices may interfere with the operation of this noise meter.

It work as intended, the app is simple to use and does not bother you with constant ads, as for the accuracy of the measurements it will depend on the cuality of the microphone you have attached to your phone. Also it only goes up to 89db, which is the safest level before you start suffering damage to your ear drums.

The app gives consistent decibel values when using it on my Pixel 2 XL, so the basics are solid. It's not my favorite, but I have Play Pass so I take advantage of how simple it is. 4 Stars: Considering it's not completely free, it would be nice to have some more features like logging or more control over the view. There are other completely free apps that give more detailed real-time information on the sound around you. It's consistent, so the dev certainly has an accurate start to build on.

Not terribly accurate, but that's to be expected. My Pixel 5 consistently read 10-15 dB lower than an inexpensive dB meter (BAFX 3370). At 100-105 dB, it read 88-92 dB, and at 45-47 dB, it read around 35. If you have access to a proper dB meter to get an idea of how accurate this app is on your phone, you could use the app to get a rough idea of sound levels when you don't have a meter on hand. The ads are very intrusive, so that's a bummer, but the app works about as well as it could.
