### 1/5 — Calculator

*2016-12-13*

Waste of money!

### 1/5 — Wasted my money

*2016-05-06*

The name says soil calculator. I bought it for a basic calculator and figure maybe I might use the other features. This app has no basic soil calculator so I just pee'd away 3.99. What a waste of my hard earned money.

### 1/5 — Save your money and skip this app

*2013-12-24*

All that's in this app is basic soil mechanics phase relationship formulae, but I expected to have the app compute several index values given say three input values.  Instead it's real basic, like gravimetric moisture content is soil solids mass divided by total mass.  Not much value here.
