XE Currency Pro for Currency Conversion
The XE Currency iOS app is not new, its interface is a bit outdated and unlike some similar apps, it only converts currencies. Still, the app is great at what it does, and the Pro version is well worth the $2 upgrade over the free XE Currency app. One cool Pro feature lets you receive "live" currency rates, which are refreshed every minute. A calculator helps figure out how much that scone with clotted cream in an English tearoom costs. And the app provides charts of historic currency information — in the case of the dollar against the British pound, the picture ain't pretty.
