Gamma Calculator Pro

Great app. Use it everyday. The new update does not seem to be working correctly. Selecting double wall thickness leads to an error in the calculator. Please explain more clearly how to use the calculator and R factors. Do the R factor densities refer to the weld or parent material?

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?

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.

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.

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

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.

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.

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.

No D3 AGFA in R factor chart everything else is great though. If you could add it that would be awesome!

An amazing tool for anybody in Industrial Radiography. I highly recommend it.
