With over a dozen scales, this is no toy. This slide rule was designed to be as powerful an one from the device's heyday. The 'auto' mode will show you how to utilize your rule.
This is no mere workhorse, either. What draws people to slide rules to this day is their simple beauty. This app captures that essence.
A slide rule is only as precise as your fingers, so what does that mean for a touch screen? Fear not! This app features a one-of-a-kind 'brakes' button which slides the rule precisely.
