Currency is a super simple, yet beautiful, currency converter for the iPhone. It features a clean design and historical charts. If you're an avid traveler or have financial interest in other currencies, Currency may be an excellent app to add to your collection.
When I say Currency is simple, I mean it. The main screen is a list of all the currencies you're interested with the primary currency at the top. So if you have 400 USD set for the main currency, the equivalent amounts for the other selected countries will be displayed below. Swiping the main amount to the right will reset the amount back to zero; sliding to the left will go back to your previous amount.
When you tap on the main amount, the keyboard will slide up from the bottom of the screen, or you can manually slide it up yourself. Swiping the keyboard to the left will review the historical data over the past six months for your #2 currency. Ordering your currencies how you want is a bit of chore, however, because they appear in the order tapped. So you if you want USD followed by CAD, then you need to tap CAD to bring it to the top, followed by USD to push CAD down to the second spot.
Although it can benefit from a few more features, especially decimals and the ability to reorder the list, Currency is a beautiful currency converter and I appreciate its simplicity. There's a lot of potential in this little app.
