### 1/5 — Useless!!!

*2021-06-27*

It’s about 115 degrees outside (typical desert summer). I was concerned about my phone’s internal temperature. This app said that it was 32 degrees Fahrenheit. I doubt that. It also said that my device wasn’t connected. I allowed all of the access that it asked for. Still didn’t work. There’s no way to check or change settings. I don’t understand why this useless application is in the App Store.

### 1/5 — Garbage!!

*2016-04-20*

I agree!! Garbage!!

### 1/5 — Don't bother!!!

*2016-03-26*

### 1/5 — Garbage

*2015-07-21*

Who designed this garbage????

### 1/5 — No.

*2015-05-24*

Very hard to use

### 1/5 — Read this!

*2015-03-17*

You must own the temperature sensor that plugs into your microphone jack. It says this in the description for those giving it bad reviews.

### 1/5 — Useless

*2015-03-09*

It says "device not connected" but clearly my phone is useable and connected.  

Why does this app need access to my microphone and photos?  No thank you.

Worst app ever do not waste your time read the reviews first. Doesn't work!!!! And why do they need to access your photos?that's a little suspicious!!!

### 1/5 — Doesn't work

*2015-01-31*

Not only does it not work, it wanted access to my microphone & photos.  Why would it need my photos in order to calculate the temperature?  A bit suspect, so I eliminated it.

### 1/5 — Doesn't work.

*2015-01-29*

I don't know why the person before me complained about it needing to use the microphone. I could not care less about that. It's the fact that it didn't work even when I did that. This app is a waste of time.
