Welcome to Pennyroyal Programming
Who we are
Pennyroyal Programming brings 30 years of software development experience to the creation of IPhone and IPad. Our first application was WoodworkerCalc, the first calculator design specifically for fine woodworkers or anyone needing an easy-to-use calculator that handles fractions. That was followed by Been There? and HK Graph.
