Banca is very minimal and straightforward, with just one goal: the simplest possible conversion from any, to any, currency. We often find ourselves needing conversion from Dollars to Pounds, or Euros or, as I encountered recently, Yen — and vice versa all around. Well, with Banca, Conversion happens as you type, to multiple currencies at the same time. And the exchange rates are automatically refreshed on each app start. Banca even uses your location to automatically include the currency for the country you are in. Certainly the most clever and fastest currency conversion app I’ve seen.
Unitica is equally as clever and well thought out when it comes to unit conversions. The truth is, for converting units we generally are converting the same unit types (inches to feet, meters to miles) over and over again. This is why Unitica allows you set any number of pairs of units as a favorites, regardless of its category and have them all available from the same screen. This saves a ton of time and allows you to quickly get to the things you most often need to convert.
For a limited time, these apps are being sold as a bundle called Convertica for 30% off the price of the two alone. Sure, you could get them separately for a fair price. But, both are so useful and well designed why not get them both and save a bit of time in the process?
