Comments on Decibel X - Pro Sound Meter for Android

★★★★☆ Emman Cian · Jun 1, 2026

Yoo, this app is perfect the Spectrogram for analyzing sounds and effects, but can you add files to put on the spectrogram and other audio analyzers on this app? I Appreciate it 😊

★★★★★ Harper · Mar 14, 2026

1 trillion times better than voli, delete voli if you have it

★★★★★ sahidul alam · Jul 14, 2026

Very good app, easy to use and read the frequencies almost correctly

★★★★★ Olav Døvre · May 27, 2026

Beautiful, it even measures frequency and what frequency has what intensity. Love it

★★★★★ Stephen · Aug 1, 2026

Did exactly what I needed it to do. I love the 5-sec video record feature that displays the sound levels. I was able to provide a local manufacturing plant proof that the noise level from coming their factory was in tolerable.

★★★★☆ Sheikh Lab · May 11, 2026

Hi The app is very good. 1. Can it give me the csv files of decimal values without saving voice recordings. For example can we disable the voice recording feature but still get the csv file with readings 2. Can it record 24/7 ie non-stop and for how many days 3. Is voice saved only on my device or is it uploaded to your servers too.

★☆☆☆☆ Stephanie · Feb 12, 2026

The support feature does not provide support. App says it's recording, but nothing is saved. Don't waste your time.

★☆☆☆☆ Dana F · Mar 25, 2026

don't see the ability to connect a Bluetooth microphone, if it is there it's labeled wrong. Also why do we need a subscription for this? This should be a one-time purchase

★☆☆☆☆ Andrew D. Royappa · Jun 10, 2026

When you rotate your phone while measuring sound level, it screws up the sound measurement after rotating back (measures everything 150+ dB constantly). Have to fix by clearing storage and cache. Been doing this for several months

★☆☆☆☆ Da Skate · Jul 13, 2026

Why does a sound app need video access? Also, the app doesn't even provide the correct decibel readings.
