About this app
Currency is a currency converter by Jeffrey Grossman that has been on the App Store since 2008. It provides current exchange rates for more than 160 currencies and countries and is designed for quick conversions, which makes it useful when travelling abroad, shopping from overseas stores or checking prices in another currency. The app runs on iPhone, iPad and Apple Watch, so conversions can also be checked from the wrist. Currency is free to download with ads; an optional Currency+ annual subscription removes the ads and unlocks the app's additional features. Version 8.1, released on October 17, 2026, carries a single line in its release notes: optimized for iPhone Duo. The developer has not published further details about how the layout changes on the foldable, so the listing reflects only that statement. We list Currency under Finance as a utility for converting amounts; it does not provide financial or investment advice, and exchange rates shown in any converter can differ from the rates a bank or card issuer actually applies.
