Comments on Sound Spectrum Analyzer for Android

★★★★★ Aditya Dixit · Jan 20, 2026

Had some bassy lower frequency noise in my home. This app showed that noise with frequency. Relived that the sound is not just in my ears.

★★★★★ Kyle James · Jul 3, 2026

Wonderful clear readings from this app. Thank you so much

★★★★★ Christie Stratton · Jan 17, 2026

Successfully capturing criminal evidence with this app. Thank you.

★★★★★ Cuong D. Nguyen · Jun 14, 2026

Easy to use - just what I wanted! Will purchase the ad-free version after a couple of days use.

★★★★★ Hrachya Ordukhanyan · Jan 4, 2026

It's great. I tested my gear with that, it was accurate 👍

★★★★☆ Stay Awake · Jan 4, 2026

Simple and nice app! Could use something like "lingering bars" feature to keep showing bars for a bit longer if bars are jumping too fast

★★★★☆ Darren Smith · Apr 7, 2026

It would be really useful to have an export function with recorded sound values in a table

★☆☆☆☆ Alan Wilson · May 1, 2026

Having an app that specifically states you must grant all permissions in order to use the app is absurd! Specify what permissions are needed, then I can choose yay or nay for permissions. I immediately uninstalled this app.

★☆☆☆☆ Robert C · Jul 17, 2026

No longer accurately identifies frequencies. My profession is acoustics, and when I tested the latest version with my calibrator, it identifies a 1000 Hz pure tone as 1500+ Hz! Not close.

★☆☆☆☆ Brandon OToole · Apr 23, 2026

Ads are invasive and make it useless. Each time I click the tone generator, it launches an ad. it would be nice if there was a timeout, so ads are not triggered back to back.

Trust & Safety: The app requests standard permissions for audio input, network access, storage, and ad services (READ_EXTERNAL_STORAGE, RECORD_AUDIO, INTERNET, ACCESS_NETWORK_STATE, WAKE_LOCK, FOREGROUND_SERVICE, com.android.vending.BILLING, and ad IDs). It uses ads and analytics libraries (facebook_ads, admob) and maintains a set of AndroidX components. This is typical for a free app with ads; safety hinges on proper permission use and trusted integrations.
