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 regards can be much more useful than calculators.

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

There are 80 different scales in iSlideRuleHD. From the scales provided, 15 can be selected for the top and bottom rules, as well as the slide, in groups of 5 scales each. Double-tapping each rule selects the next group of 5 within the application. Additionally, a two-finger pan on the slide allows seeing either the left or right index.

The application supports all orientations, rotating the slide rule to take full advantage of the display, and has 11 selectable color schemes to customize your slide rule to your favorite color. A single-finger swipe on the cursor up or down dynamically changes the color scheme.
