## Most critical reviews (3 lowest-rated)

### 4/5 — Brilliant

*2014-11-21, version 1.0.2*

Great app easy to use for finding angles and measurements, use this on iPhone6 to help survey roofs to find slope length, saves loads of time, if it was available on iPad Air, I would have given it a 5..

### 5/5 — Thanks

*2012-06-30*

Even Pythagorus would be impressed. So simple yet so beautiful. This just made trig functions obsolete.

### 5/5 — Brill

*2012-02-21, version 1.0*

Simple and Brill
