### 5/5 — Healing

*2026-08-05, version 4.11.0*

Know your frequencies this product works

### 1/5 — Insane amount of ads

*2026-07-12, version 4.11.0*

Most annoying app I have ever used.  It played 6 ads when I clicked on various parts of the app to see different menu options. I never even got to playing a sound before I uninstalled it out of disgust.

### 5/5 — Works

*2026-07-11, version 4.11.0*

Works

### 1/5 — Why Remove the Mosquito Repelling Function!!

*2026-06-25, version 4.11.0*

I bought this app a while back for the mosquito repellent function. You used to be able to push the button and the sound would just play until you turned off the app. Now they set the feature so you have to manually hold the button down. Once you raise your finger up from the screen the sound stops. It is no longer auto play. Why would anyone go out of their way to make it function that way? Useless now, which I won’t be subscribing to the app anymore. Will look for an alternative.

### 5/5 — Optional

*2026-06-12, version 4.11.0*

Optional

### 5/5 — No BS and ACTUALLY FREE

*2026-05-22, version 4.11.0*

First app that’s not actually lying when it says free. It doesn’t hammer you with promo offers for the full version and it instantly works if you need a precise frequency to immediately play/utilise

### 5/5 — Gimmick

*2026-04-27, version 4.11.0*

I use this to mess with people all the time.  Pretend like you don’t hear anything but play super high pitched sounds through Bluetooth speakers

### 5/5 — рвдызытьф

*2026-04-05, version 4.9.0*

тылыдытйдцд

### 2/5 — limited listening ability

*2026-02-16, version 4.6.0*

I love that you can choose the exact & specific frequency that you want (instead of only having options of preset frequencies). I hate, & will be deleting this app after this, that I cannot listen to anything else & have the frequency continue to play in the background, such as a YouTube video for example.  I want to listen to a video & still hear the frequency I’ve chose, play in the background.

### 5/5 — Excellent

*2026-02-15, version 4.6.0*

I’m experimenting with frequencies and this surprisingly works it makes any frequencies u want
