Units avoids needless scrolling through its sizable library of measurements by letting you search and favorite pairs of units, which saves oft-used conversions in a personalized list. The app can make conversions for just about anything you can think of, like units of data, force, luminance, and time. Like similar converters, the design is split between two columns of units, which you simply line up to make a conversion. A basic calculator is built into the app so you can perform basic operations like adding and multiplying. The app is fully customizable, letting you change the font, font color, and background color, so you can mix and match styles to your liking. The app’s $2.99 on the App Store.
Units doesn’t convert currencies, so for that you may want to check out Banca instead.
