User Reviews

This app implements a slide rule very well and its usability is excellent. Zoom and reversals are intuitive and pleasant to use. The scale arrangement (especially the LL scales) are a bit unusual, but this is secondary to demonstrating the principles of the slide rule.

It’s cleverly designed so you can actually use it from your phone. It includes integrated tutorials which actually teach you how to use a slide rule. Haven’t found any other SOS which do the same. Is great!
