Our verdict on StashFX
StashFX is a browser-based currency converter and calculator for travelers who need quick reference conversions across more than 160 currencies. It supports searching and adding currencies, displays large numbers for showing sellers, and provides mid-market reference rates for informational use. The app works on the web, iOS, and Android, with an installable home-screen experience for mobile or desktop access.
The Free plan costs nothing and includes currency conversion, a calculator, offline use after the first visit, and no ads or account requirement. When online, exchange rates update automatically each day, then cached rates remain available on the device for offline conversions. That combination suits travel situations where connectivity is intermittent. StashFX can be opened in a browser or added to a device home screen, making it practical for solo users and small teams that want a lightweight utility rather than an account-based service.
Its main strength is broad offline coverage without setup beyond the first visit. The trade-off is a narrow feature set: StashFX does not provide conversion history, rate alerts, or richer analysis. Daily reference-rate updates also depend on reconnecting to the internet, and actual bank or exchange-bureau rates may differ from the displayed figures. Choose StashFX if you value free, ad-free access and offline conversion across many currencies; choose another app if monitoring rate movements, reviewing past conversions, or comparing more detailed exchange information is central to your workflow.
