### 2/5 — Can not listen on headphones.

*2022-10-23, version 3.0.1*

I like that this app is truly free and doesn’t make me purchase anything. I will watch ads. That is not a problem, but I do have a problem with this app not connecting with my Bluetooth headsets. It will connect when an ad is on, but once it goes back to the music, then it’s only on the phone speakers.

### 1/5 — Volume jacked

*2022-09-29, version 3.0.1*

You can’t adjust volume. They have presets and they are loud. Volume 1 is like 3 or 4.

### 2/5 — Not compatible with AirPods

*2022-04-05, version 3.0.1*

Doesn't work with air pods for whatever reason it defaults to phone speaker every time. I tried other apps (YouTube/Spotify/IG) to tat sound come back to this and auto disconnects from airpod pro every single time

### 3/5 — App not working with AirPods

*2022-04-02, version 3.0.1*

Maybe I am doing something wrong, however the audio fails the come through AirPods.

### 1/5 — Does not sync to AirPods

*2022-02-19, version 3.0.1*

Garbage app. No settings

### 1/5 — Won’t work on your headphones

*2022-01-17, version 3.0.1*

App use to be good, but now won’t play through headphone which kind of defeats the purpose.

### 2/5 — Wont work on headphones

*2022-01-04, version 3.0.1*

I would really like the way this app works if I could only use my headphones. Will not play through them. All other apps work fine with them.

### 4/5 — Headphones won’t work anymore

*2021-08-24, version 3.0.1*

Love the app. But now headphones don’t work I tried both AirPods and beats neither worked

### 2/5 — So hard to use!

*2021-05-17, version 1.0*

This was a horrible app.  I deleted it yesterday because it is entirely up to the user to figure out how to best use it. Moving between brain waves relief on minuscule + - .  It was slow, unresponsive and for a relaxing app it created too much stress!

### 4/5 — Great app, small glitch

*2021-05-10, version 1.0*

It’s a great app, but for some reason it is inconsistent about playing in the background. Sometimes it plays just fine with the screen locked, other times it won’t. 

Really would get more out of it if it played in the background more often.
