Unit converters are amongst the most popular apps in the Store – there is certainly no shortage of them. For this app the developers have obviously paid more attention to functionality, rather than design. The application features a very classic look and is based on older calculators. However, it is the functionality that counts, and not the modern look.
This is where Units has quite a lot to offer – even if the clothing sizes are missing. Besides the classical conversion features you may calculate the dioxide emission of your car. This is definitely not something for everyday use, but a nice gimmick. Another fine option: simply shake your iPhone to go back to the initial screen. Also, while you are inputting values the app automatically starts to convert, so there is no need to push any additional buttons to get to the final result.
