Simple Inch app for iPhone and iPad

Simple Inch provides a simple means to convert from feet and inches to metres or centimetres by sliding a finger across the iPhone screen. The display separately shows the inches and feet values; touching either sets the slide to increment in units of that value, changing the metric display accordingly, in a large, easy to read font. The sensitivity of the slide - how much the units increase (or decrease) with a given slide length - can be controlled through the properties of the app. Rotating the iPhone provides different interfaces for left- and right-handed users; double tapping the slide-area resets the displayed value to zero.

Simple-inch: the simplest route from imperial to metric measures.
