SlipStick – the Virtual Slide Rule

Get the SlipStick App on the iOS App Store

SlipStick is a fully functional virtual slide rule, faithfully replicating this vintage mechanical calculating instrument.

Use SlipStick by sliding the frame, slide and cursor to make calculations. The slide can be moved in a slow precision mode by keeping one finger on the frame, and moving the slide with another finger.

The SlipStick replicates a double-sided slide rule – one side has multiplication, division and trigonometry scales, and the other side has logarithm, exponents and folded scales. To switch between the two sides of the slide rule, just flip your device between landscape left and landscape right orientations.
