Have you ever used a slide rule? Ever been curious about the way slide rules can be used to solve complex math expressions? Would you like to learn how slide rules work? Slide rules were used for literally hundreds of years before calculators and in some areas can be much more useful than calculators.

iSlideRule is a fully configurable slide rule app supporting multiplication, sines, tangents, cosines, cotangents, roots, squares, logarithms, and hyperbolics.

There are 80 different scales supported by iSlideRule. From the set of scales provided, 12 can be selected for the top and bottom rules, as well as the slide, in groups of 4 scales each. Double-tapping each rule selects the next group of 4 within the application. Two-finger panning on the slide provides viewing of the index ends, while one finger swiping on the cursor changes color schemes dynamically.

The application supports all orientations of the handheld, rotating the sliderule to take full advantage of the display, and has 11 selectable color schemes to customize your sliderule to your favorite color.
