## Most critical reviews (6 lowest-rated)

### 4/5 — Great App for Cathodic protection technicians

*2015-05-10, version 2.2*

This is a great App for calculations dealing with Corrosion mitigation. The only downside is it would be beneficial to see the use of negative values added to the Linear interpolation/extrapolation models to mimic negative values used in an Evans diagram.
