### 1/5 — Kinda useful, but requests microphone

*2015-03-01*

It's kind of useful for some things, I used it for a math project. However the app requests to use the microphone, and seems to be recording something even when the camera feature is off (red banner at the top, like when on a Skype video call). I don't know why it needs to do that or why it needs to record audio. Big big privacy issue.

### 3/5 — it's just ok

*2013-09-20*

it's really frustrating that you can't rotate the app 180* when you try to use the camera the lens gets blocked by your hand holding the phone. please fix this!

### 4/5 — not bad

### 5/5 — Wonderful !

*2016-07-27*

As an architect I often have to make quick sketches for my clients.  This is a wonderful tool for estimating ground slopes and grade heights. Recommend it highly.
