### 4/5 — Merging frequencies

*2025-11-02*

I can’t find how to remove additional merged frequencies in the app. Can someone explain how this is resolved?

**Developer response:** Just slide the item you want to remove the left, you will see Delete button

### 1/5 — What happened

*2024-01-13*

You use to be able to go over 20khz?

**Developer response:** No, the frequency limit for audio devices is 20kHz.

### 5/5 — Great app, with hidden benefit

*2019-11-01*

This is a great app for generating tones but has a very useful feature: the ability to generate clicks with a custom duty cycle. In particular, the app can replicate the precise 40Hz tone shown to have therapeutic benefit in mouse models of Alzheimer’s Disease. Just navigate to ‘clicks’, select On-Off frequency of 40 Hz, On frequency of 2000 Hz and On-time of 0.001 sec (4%).

### 5/5 — DC Offset

*2019-02-05*

I searched through all the other signal generators to find one that contained a dc offset.  This was the only one.  Really great control on the app!
