About this app

This is the fastest, easiest app to square your foundation, floors or wall. No having to deal with pushing buttons for feet, inches, rise, run or diagonal. Just fill in the blanks and everything is calculated for you. There's not even an equal button to push. It can even deal with measurements just in inches and non-standard fractions.

Ratings and reviews

I tried a simple 20 x 30 calculation to find the diagonal. 20 squared plus 30 squared is 1300. The square root of 1300 is 36.0555 which is 36 1/16 to the nearest 16th. This app says 36 11/16 (off by 1.7%) Rounding errors are common with binary languages when converting between decimals (base 10) and base 2 (which programming languages use). However, there are workarounds. I asked AI "square root of 1300 converted to sixteenths" and it gave a simple methodology which gave the correct answer.

Very simple to use, very easy to understand, and very handy to have!

Can get a setting for dark mode it will be plus
