a2zpro is the successor to a2z from UK iPhone app developer Westernits and it is a truly innovative tool as far as conversion apps are concerned. Upon every opening of a2zpro the exchange rates are updated for the currency converter, which provides 154 categories with live data from Yahoo!. The currencies work slightly different than in other apps since the user selects the currency and amount and the other 153 conversions are shown underneath (no from-and-to selections are needed and the page is not limited to only a few units). Furthermore a2zpro includes the unusual category of Blood Sugar, which might come in handy for some users.

While a2zpro offers slightly less units per category when first installed, this app allows users to add their own categories, which can then be uploaded to the Westernits server, where other users can browse and download additional units. This is a beneficial and functional option, which allows each user to create their own personal converter according to their conversion needs. Another great tool is the ability to shift categories on the lists, allowing more user-defined use. With a2zpro being free and offering this much user integration there really is not much left to be asked for.  Great app!
