Ever heard of a slipstick? Or, more appropriately, a slide rule?! What the heck is that? Before scientists, mathematicians, and engineers had fancy calculators, they had to rely on the slide rule for their rapid number crunching.

Thanks to the AWESOME POWER of logarithmic scales a slide rule gives you several computational features using your very own virtual, mechanical computer. With this slide rule, you can: multiply and divide, multiply chains of numbers, find reciprocals, determine squares / square roots / cubes / cube roots, base-10 logarithms, and sines / cosines / tangents / cotangents.

Contains support for both phone and tablet devices. Provides ANIMATED built-in help for maximizing your slide rule usage.

This app will definitely help establish your nerd-cred.

    Using it to show my daughter how a slide rule works. It has mathematical ideas like Logarithms as part of it's functionality. Some of the ideas are not even taught any more, because calculators make the work obsolete. Wish it had more scales available. I thought the colors worked pretty well, they emulate an old Pickett slide rule, and are easy to read.
