Currency Converter Plus review
A feature-rich iPhone converter for custom rates, crypto, metals and offline use.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Currency Converter Plus is a freemium mobile conversion calculator from Kaspre Invest Ltd. It is aimed at travelers and people handling international transactions who need currency, cryptocurrency and precious-metals conversions on iPhone or iPad. The app combines live exchange rates with offline conversion, a calculator-style input interface, custom exchange rates, favorite currency-pair tabs, interactive historical charts and date-based rate lookup. Its published feature set covers 173 world currencies, alongside crypto and metals conversion.
The free plan provides the core app, while the paid catalog is divided into focused options. Enable Calculations adds calculation functions, Enable currency rate editing allows custom rate changes, Premium for a Month and Premium for a Year provide premium access, Remove Ads removes advertising, and Unlock Tabs adds favorite-pair tabs. This structure lets a user pay for a specific capability or for broader premium access rather than relying on a single upgrade. The calculator, historical lookup and custom-rate tools give the app more depth than a basic spot-rate converter, particularly when a traveler needs to work with an agreed rate or review past values.
Platform fit is narrow: distribution is through Apple’s App Store for iPhone and iPad, and the listing is not verified for macOS. Support is provided by email. Choose Currency Converter Plus if offline access, custom rates, historical charts, crypto, metals and an iOS calculator matter in one app. Consider an alternative if you need Android, desktop compatibility, or a support channel beyond email.
