OANDA Currency Converter review
A free converter with deep historical data, broad coverage and iPhone charts.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OANDA Currency Converter is a free web calculator and iPhone app for converting currencies with OANDA Rates. It suits travelers, freelancers, small businesses and researchers who need a straightforward conversion tool with historical context. The web converter handles world currencies, precious metals and obsolete currencies, while the iPhone app adds charts and analysis tools. Its company profile and free access make it practical for solo users through mid-market teams that need occasional or recurring rate checks.
The main strength is breadth over time and instrument type. Web access includes rates for 212 currencies, with historical exchange rates reaching back to January 1990. Users can review exchange-rate charts and apply interbank-rate or percentage-add-on options in the iPhone app. Daily-filtered OANDA Rates keep the workflow simple for routine conversions, but the daily refresh cadence is less suitable for decisions that depend on intraday movement. Coverage also varies by platform: the iPhone listing advertises 300+ currencies, while the web converter specifies 212.
Platform fit is the key trade-off. OANDA provides cloud web access and a dedicated iPhone app, but no Android app, so Android users need another converter. The product is a strong pick for anyone prioritizing long historical records, metals and obsolete currencies, or chart-based analysis on iPhone. It is less suitable for users who require Android support, continuously refreshed rates or identical currency coverage across devices. Teams seeking a free, focused converter will find the feature set appropriate without a paid tier to evaluate.
