## Most critical reviews (4 lowest-rated)

### 1/5 — There is bug!

*2024-08-17*

If I try 11 inch - 9 inch….impossible to select after 9!

### 1/5 — Won't do negative numbers

*2022-01-28, version 6.1*

Useless for calculating elevation because if you go below 0 it can't do the math. Only good for work with no underground.

### 5/5 — Great and free

*2024-10-04*

Thanks for the app. It’s super helpful. The app takes a second to figure out. Fractions are not something I want to have to do off the dome all day. It’s get tiresome. Also useful for double checking your work. - Electrician

Best construction calculator on the market hands down. Simple, intuitive and accurate.  
Great app. Wish I had found it years ago.
