iSlideRuleHD 3.1.1

The iSlideRuleHD application represents a highly versatile digital slide rule, offering extensive configurability to support various mathematical operations including multiplication, trigonometric functions (sines, cosines, tangents, cotangents), roots, squares, logarithms, and hyperbolic functions.

With nearly 100 different scales available, iSlideRuleHD provides comprehensive support for multiple types of calculations, including those suitable for dimensional analysis. Users can choose from 15 predefined scales for the top and bottom rules and the sliding component, organized into groups of five. Double-tapping any of these rules facilitates the seamless selection of the next group of five scales. Additionally, a two-finger horizontal pan over the center slide enables viewing of either the left or right index of the slide rule body.

The application is designed to adapt to all device orientations, automatically rotating the slide rule to optimize display usage. It also offers multiple color schemes, which can be easily customized; a single-finger swipe up or down on the cursor dynamically switches between available color configurations.
