### 1/5 — Nothing!

*2021-06-14, version 2.1.5*

Every time I try to use this, I find another of my Bluetooth devices this does not work with. I have yet to find a single one that it does work with. I suspect that any devices it would work with, probably have their own apps that perform this function… for free.

### 1/5 — No Good app.

*2021-04-13, version 2.1.5*

Ok. You warned me but, l had to for $1.99 found out myself. The app didn't pick up my apple watch or iPad. Save your money or give it away here.

### 1/5 — NOT for AirPods

*2021-01-21, version 2.1.5*

Does NOT work with AirPods

### 1/5 — This app said I had a virus 39 on my iPhone

*2020-10-19, version 2.1.5*

This app claimed it supported Apple Bluetooth for the battery and it doesn’t support it at all this is not a joke just a better joke should never be allowed and I want my money back

### 1/5 — Doesn’t work

*2020-09-28, version 2.1.5*

Will not work for me!

### 1/5 — Dose not work with all Bluetooth devices in fact hardly any

*2020-07-15, version 2.1.5*

Beware this app dose not work with all Bluetooth devices in fact hardly any.  Wasted my money so please don’t waste yours... 0 stars is my true score.... All BAD !!!!

### 1/5 — No good

*2020-06-06, version 2.1.5*

Not compatible with any device I have tried it on

### 1/5 — Lame

*2020-04-24, version 2.1.5*

So basically they trick you into buying their app with the promise of monitoring Bluetooth battery levels only to find out that NOTHING is compatible with the app. Enjoy taking my $1.99 for doing nothing.

### 1/5 — Less than 1 Star

*2019-04-19, version 2.1.5*

If I could have rated this 0 Stars, I would have.  My Bluetooth Devices are not “Smart”... which apparently this app needs.
Does not work with my BT Headphones.  Glad it was only $2. I guess maybe that is the only redeeming quality for me.

### 1/5 — Apple AirPod

*2019-02-12, version 2.1.5*

Disappointing that this app does recognize Apple AirPod
