Developed to train myself, this is a valuable App for those who want to become better with their slide rules—or even those who just want some practice with mental arithmetic estimation—RuleCoach is both a coach and a proctor that aims to improve your speed and accuracy with your slide rule.

Exams cover a wide range of scales found across many rules, and includes helpful instructions that will guide you in calculating solutions!

Includes a unique calculation error metric calibrated to the linear misalignment of the physical components in addition to traditional calculation error percentages.
