NDConvert
December 7, 2009
NDConvert was an app for iOS devices I developed with Matthew Kidd in the first years of the iOS App Store. NDConvert was retired in September 2016, its app description is below.
NDConvert focuses on reliability, speed and usability through rigorous cross checking of conversion data and by minimising unnecessary animations present in other unit converters.
The iPhone edition is available on the App Store and features an elegant user interface, quick switch between units from and units to, automatic calculation of conversions, conversion history navigation and large keypad buttons to minimise input error.
Unit categories included in NDConvert include Acceleration, Angles, Angular Acceleration, Area, Molar Concentration, Charge, Currency, Data, Density, Electrical Conductance, Electrical Inductance, Electric Potential, Electrical Resistance, Energy, Flow (Volumetric and Mass), Force, Frequency, Fuel Consumption, Heat Transfer Coefficient, Heat Flux Density, Length, Magnetic Flux, Magnetic Flux Density, Moment of Inertia, Power, Pressure, SI Prefixes, Sound, Specific Heat Capacity, Surface Tension, Temperature, Thermal Conductivity, Thermal Resistance, Time, Velocity, Viscosity (Kinematic and Dynamic), Volume, and Weight.
With 645 different units and 38 different unit categories you can be assured that the unit conversion you need is available without having to sort through thousands of redundant units.
