“It´s not just for geeks anymore! The ℠Virtual Slide Rule´ app has instructions so even people not familiar with how to use one can learn — like me. Always wanted to know & now I can.” (coolshades2002, Apr 11, 2011)
Bob Gordon, co-founder of the Interrobang Group said, “Slide rules are simply cool. I´m happy that our virtual one has been well received. We wanted to price it at $3.14 for the sale, but the App Store won´t allow that. Everyone should thank Apple for the extra fifteen cents savings.”
