To celebrate Pi day (March 14), the Interrobang Group is having a sale on its Virtual Slide Rule iPad app. Normally $4.99, on Pi day it will be available for $2.99.

The Virtual Slide Rule is an iPad-only app that duplicates a slide rule perfectly. It includes instructions on how to use it as well as links to further information about slide rules.

Users rate it five stars in the Apple App Store:

“This is an excellent electronic slide rule. It is easy to use and has a reasonable number of scales. It is perfect for the novice or collector.” (Boyle67, Oct 29,2011)

“This is really a fantastic app. It works exactly like the real thing, and it is terrific to look at. It´s a great app for a math or science teacher to show to his class. This app keeps a part of math history alive. I love it.” (Winton Teter, Jun 29, 2011)

“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.” (coolshaeds2002, 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.”
