“This app is so good that Apple should use it for their default calculator! Great UI and great features.”
“I have found this app to be so helpful. It gave me the latest conversion rates immediately! Even the vendors in the country I visited argued with me until they went online to update their systems...they of course apologized and conceded to my pricing. I don't need anything else...I'm sold!”
"I was looking for clean simplicity in a calculator, and found it here! Often need to travel between 4 or 5 customizable countries, and finding the currencies was very easy. Thanks!”
