Currenci is a new app for iPhone that does something travelers will vastly appreciate. It offers a widget from which you can perform fast calculations and currency conversions for when you're on the go! The app itself is pretty simple offering the basic functionality you'd expect. But for the price of free this is an app you can't miss. Download it now on App Store.
If you're like me and take a lot of screenshots but don't bother to delete them afterwards Screeny is the app to use. It saves valuable space on your iOS device by scanning your Photo Library and deleting these screenshots.
