### 1/5 — I wish I knew where the saved file is

*2026-07-17*

There does not seem to be a way to control where the wav file is saved. I got the paid version so I could export and save, but there is no way to export to my “Files,” and I can’t find the file to copy it over to Files. I need the tone so I can import it into an audio editor to include verbal suggestions. This file I generated here is simply for brainwave entrainment.  I love how simple it is to create the file. It would be nice if I could save it somewhere that I could use it in an audio editor or export the brainwave entrainment file to my phone or other device.  I don’t want to ftp anything. I need “export to” so I can save it to files.  I would give you 5 stars if I could add that to how simple it is to create the monaural beats track. I can’t very well use the file if I can’t put it in an editor or export to another device. It doesn’t even let me email. It says to set up email in the apps email settings, but there is no field for this. The app sucks without any type of way to export / save files to a specific location on Files or to share it.  I would love to have my money back unless you fix that. And if you fix it, I would give it 5 stars.

### 2/5 — Input needs work

*2026-01-25*

Unable to manually enter numbers- this is an easy fix. Do better

### 2/5 — Looks nice, doesn’t play nice

*2025-11-15*

The user input is horribly glitchy, I can’t manually input a number nor can I reduce the frequency unless it’s a random 600 something hz jump each time, and can only manually increase it by 0.1hz each time I press the 7 8 9 numbers…backspace doesn’t work either. 

If they fixed the unusable bugs I would try it again, but this amount of issues seems fishy

### 2/5 — Для детей

### 1/5 — Do not buy

*2024-11-03*

This app shuts down and cannot be restarted immediately after purchase. Don’t waste the $5!

### 5/5 — Perfect!!

*2024-01-27*

Wired up a subwoofer on the top of my book shelf, nearest the ceiling, and I can’t hear my noisy upstairs neighbors that I’ve tried to work with. Can’t beat em, join em. Right? 32Hz sine wave keeps them happy!

### 5/5 — How to use for sleep

*2023-04-21*

Tone 1: 340 Hz
Tone 2: 342 Hz
Excellent results!
