Our verdict on Show Currency Converter
Show Currency Converter is a free currency-conversion app for iOS and Android, aimed at people who need quick everyday reference rates. It converts amounts between currencies using European Central Bank reference rates and an open exchange-rate API. Rates are cached on the device, so conversions continue without an internet connection. No account, advertising, tracking, or sign-up is required, and entered data stays on the phone.
Its platform fit extends beyond the mobile apps through a free developer rates API. The API requires no key and has no rate limit, making it accessible for small projects and solo developers. The published API information says its data file is refreshed twice daily, while the underlying rate sources follow different update schedules. The app itself is offered on a single Free plan covering currency conversion, offline use with cached rates, and access without an account.
The main trade-off is intended use: the product is positioned for everyday reference rather than financial settlement. Offline values depend on when the device last cached rates, and source update schedules are not uniform. Choose Show Currency Converter if you want a straightforward mobile converter without ads or tracking, or need a simple API without authentication overhead. Choose another tool if your workflow requires settlement-grade processing or continuously refreshed rates as a core requirement.
