I hate to bring up the true north subject and I know that it is not super
critical with a four square but I was wondering if there is an app or a some
semi-accurate modern way to layout a four square instead of a compass and
tape measure. My phone's (Android Samsung S23) compass app shows true north
however I get varying results, I supposed depending on calibration and
perhaps how level the phone is. I also tried a GPS coordinate app to
layout the pattern but it shows an accuracy of 12 feet. In actuality it was
4' different between points than my tape measure.
