iSlideRule

iSlideRule is a fully customizable sliderule app supporting multiplication, sines, tangents, cosines, cotangents, roots, squares, logarithms, and hyperbolics. There are nearly 100 different scales supported by iSlideRule, including scales for dimensional analysis. 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. A two-finger pan left or right on the center slide provides viewing of the index ends, while one finger swiping up or down on the cursor changes color schemes dynamically. The application supports rotation of the handheld, allowing the sliderule to take full advantage of the display, and has 11 selectable color schemes to customize your sliderule to your favorite color.
