Currency Converter – Rates review
A free Android converter with live Frankfurter rates, history and offline caching.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Currency Converter – Rates is a free Android app from ByteBeast Software for people who need straightforward currency conversion on a mobile device. It pulls live exchange rates from the public Frankfurter API, lets users convert one amount into all supported currencies, and includes search, favorites, rate-date display and manual refresh. No account is required. Local history keeps previous conversions on the device, while light and dark Material Design 3 themes and 12-language localized currency names support everyday use across different preferences.
The published offering is a single free plan rather than a tiered product. The app is financed by advertising through Google AdMob, so there are no paid feature levels described. Its main external dependency is the Frankfurter API, whose data is described as ECB-backed. This keeps the app focused on rate retrieval and conversion instead of adding a broader financial platform. Email is the listed support channel, and GDPR is the stated compliance posture. For solo users and small-scale personal use, the simple pricing model avoids subscription decisions; organizations seeking administrative controls or service-level options should look elsewhere.
Offline capability is the standout feature. Cached rates allow conversions without a connection, and favorite currencies receive a background refresh every 24 hours. Users can also refresh rates manually and see the date attached to the available rates, which helps frame offline results. The trade-off is breadth: deployment is limited to Android, and the feature set centers on conversion, favorites and history rather than advanced analysis or multi-platform access. Choose it for free, practical Android conversion with a local record of past calculations; choose an alternative when cross-platform availability, richer financial tools or an ad-free experience is a priority.
