Comments on Sound meter : SPL & dB meter for Android

★★★★★ Nikos Kosmas · Jun 27, 2026

Very good app and with a little calibration for my mic it is working just fine.

★★★★★ Boyan Kalinov · May 23, 2026

I'm not sure how accurate the app is, but it's easy to use and does what it is supposed to do.

★★★★★ mI573R foXy · May 14, 2026

Does what it does. For being a free tool easy and simple ui showing from the get go the db. With a bar providing you information in which sound environment the noise is peaking. For a first proxy nice app.

★★★★★ Mark Wilson · Jun 5, 2026

DB Meter app that works well and had reference points along with active scale. Good stuff!

★★☆☆☆ Moonseok Kim · Jul 1, 2026

The calibration doesn't seem to work as intended. When I put +6dB calibration, it actually applies +12dB instead. Need to be fixed for the quick measurement purpose.
