I’m a Surveyor and should be able to do this in my sleep but with all the new tools I have lost some basic skills. This app is very simple and gets me TGE answer I need in a snap.
Couldn't ask for an easier to do math. When in school we had to show our work with no calculator. Love this app.
Simple, fast and easy to read.
