## Dri-Eaz Psychrometric Calc Reviews in United States

### ****- "App couldn’t be Grater"
Today, I downloaded the Dri-Eaz Psychrometric Calculator, and it’s clear that this tool is designed for professionals with a strong technical background. The app provides detailed psychrometric calculations, essential for those in the restoration industry. However, its advanced features and data inputs can be overwhelming for those not familiar with psychrometric charts and concepts. Overall, it’s a specialized and highly technical app best suited for experienced users.

### *---- "Gpp app"
It seems this app needs updating to ios11.0 it no longer works on either of my iPhones
Sure would love to see it updated
-- restech, 2017-11-24

### ***** "Great"
This is a great app... A lot better than pulling out a grains wheel!
-- Daddy6797, 2012-03-31

### ***-- "Grate for finding GPP"
Grate for finding GPP but it would be better if we can use the app to find out the number of air movers and dehumidifiers to use. Otherwise grate app.
-- Sucker me, 2012-01-23

### ***** "Great tool"
Very simple. A great tool for water damage mitigation.
