## What is Tone Generator_Pro?

Generate various periodic signals with different waveforms with adjustable frequency and amplitude. These are used to test electronic circuits such as amplifiers and filters.

For any instrument that produces an even tone. A metronome also helps you to practise.
Drive insects away or compare your hearing ability with your friends and relatives and share your results! Or watch others straining their ears to find the sounds that cannot locate you. Party fun is guaranteed!

### 1/5 — Obnoxious and extremely annoying Ads

*2026-04-02*

Ads suddenly pop up and cover the whole screen with no options making the 20 Hz tone generator unusable.  Not like other App Ads that show up at the  bottom off the screen  and give you the option to skip Ad after 30 seconds or so if you are not interested. Terrible to use for short periods and definitely not conducive to encouraging anyone to upgrade.

### 5/5 — 天井裏の
