User reviews

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.

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?

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.

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.
