★★★★☆ 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

★★★★★ 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.

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

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

★★★★★ Kyle James · Jul 3, 2026

WARNING ASKS FOR PERMISSIONS BUT DOESN'T SPECIFY! Click on anything and ads pop-up.

★☆☆☆☆ 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.

★☆☆☆☆ Einssv Z · Feb 2, 2026

Can't open without sending your info to who knows who. Trash

★☆☆☆☆ Lenovo · Jul 11, 2026

Install demands unconditional blanket acceptance of all permissions that it never identified in order to use app

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.
