## Gamma Calculator Pro Reviews in Соединенные Штаты

### ***** "A reliable app for I-phone"
Between this app and another calculator app  (x-ray_timer) I would say my whole shop uses this app for anyone that owns an I-phone.  What drives me crazy is when you initially want to change the curie amount and the line always starts in the front of the initial number. Just an extra step moving the line to select the initial number and change it. We use this app every week here in Kansas.
-- IsaacSpangle, 2024-12-07

### ****- "Requested changes"
Can you please add the R factor for D3.

Also could you please make it so that the SFD and other measurements that need to be precise don’t round up or down?
-- fantasyenthusiast, 2024-02-22

### ****- "Works well"
The app works well on IPhone if you know what you’re doing and double checking it. There are a few mistakes with the schedule thicknesses in the calculator where some measurements are missing decimal places in front so the distance is over a hundred feet.
-- St.holierthanthou, 2023-12-16

### *---- "Fix it!"
This thing worked like a dream for years but since the update…it’s junk. Won’t even configure time on iPhone! Fix it or refund my purchase.
-- Totojoe1, 2022-09-26

### ***** "App update"
Love the app, have been using it for years, but as of today the app will not work on my iPhone after the IOS 16 update. Please fix
-- yahn2831, 2022-09-26

### ****- "R-factor"
The R-factor for AFGA D3 isn’t listed. I would like to know if this will ever be added or fixed. I love the app, but this is the problem I have with it.
-- you mess the app up, 2022-08-18

### **--- "24” Schedule 40"
App is great for getting shot times. 
Now…24” 40s and 24” schedule 40 are 2 different thicknesses. 
24” 40S is a .375
24” Sch 40 is a .688
I learned the hard way to figure that one out.
-- raddude1986, 2022-04-10

### ***** "Love this app"
Use this everyday, best app for X-ray personnel.

I wish the maker of this app would do a code app like b31.3, section 8, api 1104.
-- Horror hound 420, 2019-04-15

### **--- "No D3 AGFA"
No D3 AGFA in R factor chart everything else is great though. If you could add it that would be awesome!
-- branclon16, 2019-03-26

### ***** "Great app"
An amazing tool for anybody in Industrial Radiography. I highly recommend it.
