4/5Works 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.

5/5A 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.

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?

5/5Worth it
This is worth the money for an on the go industrial radiographer! Better than a slider even though your trusting someone else with your shot times it's never steered me wrong. Great job on the app hope you keep up with the changing of times. Thanks

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
