Currency review
A focused Apple-platform converter with widgets, offline rates, and watch support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Currency is a mobile currency-conversion app from Simple Simple LLC for travelers and other solo or small-scale users who need quick rate checks. It converts across more than 160 currencies and combines live exchange-rate updates with offline mode, historical exchange-rate charts, a calculator, dark mode, and a gesture-based interface. The product is available on iPhone, Apple Watch, and macOS, with compatibility also listed for Apple silicon Macs and Apple Vision.
The freemium model provides a free plan alongside optional Currency Pro Monthly, Currency Pro Annual, and Currency Pro Lifetime purchases. A listed starting price is 0.99, while the available purchase structures cover recurring and one-time access. The published plan names indicate flexibility for users who want to choose between ongoing subscriptions and lifetime ownership. Prices can vary by region, so buyers should review the offer shown for their location before purchasing.
Apple ecosystem fit is the clearest differentiator. The exchange-rate widget keeps conversions accessible from supported Apple devices, while the Apple Watch app extends the experience to the wrist. Offline functionality and historical charts add practical value for travel planning and reviewing rate movement without relying on a current connection. Choose Currency if you want a focused converter with calculator support, watch access, and an Apple-oriented interface. Consider another tool if your needs extend beyond currency conversion into wider personal-finance features or platforms outside the listed Apple environment.
