Unit Converter Plus (developed by Wopnersoft) is maybe not one of the good looking apps but it is made to get the job done and it does it very well through its simple, straightforward interface.

As the name specifying this app is to convert unit values. I am no expert but the never ending list of conversion options show it can convert anything you have in mind. Currency, weight, distances, data rates and it goes on and on. Neat app, very useful, very quick.

A section is for calculations with a simple calculator included. Because there is a long list of options, the app has 6 quick launch buttons in its start page where you can place your most used conversion scale to get to the business directly.
