## GDU Calculator Reviews in United States

### *---- "Instantly Crashes"
Crashes after tapping on field name. App is great when it works.
-- Farmer_Larry, 2022-09-08

### ***** "PGR calculator"
Works for calculating GDD to time PGR apps for turfgrass. I am shooting for .125oz/1k sqft every 300 GDD on 1/2” zenith zoysia. This app makes it easy to know when to reapply.
-- turfbossssss, 2021-06-12

### **--- "Ok"
I like the features of the app, but to make it great I’d like to see a five year average of GDU’s and a +/- from this year and also a +/- from last year to really know how the year is stacking up.
-- Arbananas113, 2020-08-20

### *---- "Doesn’t work properly"
This app does not configure to you screen!! So when you enter info you can barely hit the done button. Then went to edit some info and you can’t even see the done button and can’t scroll down either. BAD app
