It works

It works well. The stupid pop up asking for a review won’t go away unless you leave a review. Super annoying.
Actually it stays even after you leave a review😩 Also fractions such as 5/11 are returned. In construction only 16ths 32nds etc are used, so it isn’t much more useful than a decimal calculator until that is fixed. ,


I bought this a few years ago in a lump sum to be able to use this app for life. It got an update 2 days ago. When i opened this app today, it asked me to pay to get rid of the advertisement windows at the bottom of the screen. Really?

Developer Response ,

Hello, I believe there may have been some confusion. Until recently, our Construction Calculator app was ad-free. However, we introduced ads as a means to sustain our livelihood from the app. If you could send a copy of your original purchase receipt to our support email, we should be able to resolve this issue. We apologize for any inconvenience caused.

Mr meow OH YEAH ,


I have used this for many years and LOVED it but what in the world is this awful convoluted updated? And you changed to a subscription model? If yall had left it alone I would have considered paying a small subscription but not now!!!! This is an unusable mess!
