Converter4U is a simple lightweight unit conversion calculator for iOS. This ad-free unit converter supports most common units in the Length/Distance, Weight/Mass, Area and Temperature categories for Metric and Imperial units. The goal of the development was not to cover all possible units and categories, but to create something very easy, fast and convenient for everyday personal use. It is very handy for those who travels oversea often. Colored screens schema and category icons help to navigate quickly to the desired category. The "on the fly" conversion helps to save time if the comparison of multiple units are needed. Screen swiping is used for intuitive and quick category navigation.
