Comments on Decibel X - Pro Sound Meter for Android

★★★★★ 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.
★★★★★ 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
★★★★☆ 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 😊
★★☆☆☆ Don Mashak · Sep 23, 2026
Beautiful onscreen graphics if you can't forward them to your laptop or find the video file storage folders for an upcoming court hearing. Kept being told, play them with your camera app, the files will appear their. NO RESPONSE FROM SKYPAW SUPPORT EMAIL. NO SUPPORT OR ANY PHONE NUMBER FOR DIGITAL X OR SKYPAW. GOOD THING it has a free 3-DAY TRIAL. Unless you are a tech guru, do not buy.
★☆☆☆☆ 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.
★☆☆☆☆ Benson Tam · Aug 1, 2026
I noticed this app was accessing my microphone even when I wasn’t actively using it. A sound meter obviously needs microphone access while measuring noise, but there’s no good reason for it to stay active in the background after I’ve finished. This is a serious privacy concern and immediately made me uninstall the app. The developer needs to clearly explain when the microphone is used and ensure it shuts off completely when the app isn’t measuring sound.
