“This app is so good that Apple should use it for their default calculator! Great UI and great features.”
- OCbanker949

“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!”
- SmoothDQ

"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!”
