I have used this currency conversion app for international travel on multiple occasions and it is super helpful, seemingly accurate, and just works. Easily 5 stars for its utility and ease of use. It is also a value at $3.99 for the premium version. My only recommendation for the developer is that when selecting a currency or new currency to track, that once you select the desired currency from the list and a checkmark appears, the “cancel” prompt at top right becomes “Done” or “OK” to close the selection screen. Otherwise, thank you for the excellent application!
