### 1/5 — This appears to be a scam!

*2023-08-09*

Downloaded after the App Store said it was compatible with my iPhone 11, and bought a weekly subscription. After the app opens, there’s a “Let’s get started” button. Click that and it goes to a blank screen with a rotating cursor, acting like it’s cogitating, and nothing happens. No options, no setup , no settings, and no sound boost!  Unless they can prove to me to the contrary, I’m convinced it’s a fraud and a scam.

### 1/5 — 1 star is too high for this product

*2023-06-10*

I subscribed this week. Luckily only for a week. But it won’t discover my blue tooth devices despite the fact they are connected to my phone and no reply from customer service which is just an email. DO NOT BUY

### 1/5 — Not free

*2023-05-24*

Asked me to subscribe first thing.

### 1/5 — Can’t even tryout??

*2023-04-25*

Sorry, do you buy before you try?? 
Didn’t think so. 
Bye 👋🏼
