### 1/5 — Deceptive rip off.

*2021-10-15, version 1.0*

It’s an opaque picture of a protractor. That’s it.

### 1/5 — Ineffective protractor app

*2020-02-01*

I can’t even change the angle of the protractor😡
I don’t think you know the definition of pro.
Can give this thing some updates?

### 5/5 — Super useful! 🔨

*2019-02-01, version 1.0*

I use it to measure angles and it is great! 
It uses the camera and it makes it super easy to measure! The developer has another similar one which does not use camera and sometimes I use both.
Simple and useful! ⭐️
