While on my most recent international trip there was one App that I realized I didn't have for my iPad. I didn't have an iPad native currency converter. While I happily use Convertbot for all my unit conversion needs on the iPhone, they have yet to make an iPad native version. So I went in search of one for iPad. As you might expect there are several to choose from. Since there was one that caught my eye and it was free I decided to download it right there on the spot in the airport. The problem I have is that when I go to a country for the first time I may not even know what their currency symbol is. This usually means that I have to Google it first before I can even use Convertbot. Then I usually set the conversion to $100 US so that I'll know approximately how much walking around money I may need to withdraw from an ATM for taxis and such. XE Currency so far has fit my needs very nicely. Not only can it display 10 different currencies at once, you can search for the currencies that you wish to display by the name of the country. That ends my need to Google them. As you might expect the App automatically gets the current exchange rates automatically over the internet and you can refresh it as often as you like. You can also use the built-in calculator to figure something out before doing the conversions. You can tap on any of your displayed currencies and enter an amount in that currency and all the other currencies will reflect the conversion.
It's slick and it works! My only minor complaint about the app is one of aesthetics. One thing that bugs me is that while I don't mind the limit of 10 currencies displayed at a time, I do find it a little distracting that those 10 don't fill up the display. There is space left over that you could easily fill with 2 more currencies. This begs the question of either why is there a limit of 10 or why not design the UI so that those 10 take up the whole display? Like I said, it's a very minor complaint. Otherwise I LOVE using this App and best of all it's FREE! I didn't need to look any further. It does all that I needed.
