Currency Converter by ACKBiz review
A free, ad-supported converter for daily rates, offline access and 160+ currencies.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Currency Converter by ACKBiz is a mobile finance app for converting amounts across more than 160 currencies. It is aimed at solo users and small teams who want a straightforward converter on Android or iPhone/iPad, including situations where connectivity is limited. No account or sign-up is required, so users can open the app and convert currencies without creating a profile. My Rates provides a watchlist for following one amount across currencies, while bookmarks save frequently used pairs.
The pricing structure is simple: one free plan with advertising. There are no separate paid tiers, so the same free experience contains the available conversion, watchlist, bookmark and offline functions. Exchange rates update daily through the European Central Bank via Frankfurter and ExchangeRate-API. That schedule works for routine budgeting, travel planning and other tasks that can use a daily rate, but it is less suitable for people who need continuously refreshed market movements. The ad-supported model also makes this a less appealing fit for users seeking an ad-free currency utility.
Offline conversion is the standout capability. The app caches the latest rates and includes a bundled snapshot, allowing conversions when a connection is unavailable. Its mobile focus keeps the scope narrow: iOS and Android are supported, with deployment centered on phones and tablets rather than a broader platform ecosystem. Choose Currency Converter by ACKBiz if free access, no account requirement, daily rates and offline use matter most. Consider another converter if you need live refreshes, a non-mobile deployment or an experience without advertising.
