How Much In review
A free, privacy-minded mobile converter with offline rates, but few advanced tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
How Much In is a free currency-conversion app for travelers and shoppers who want a straightforward mobile tool. It runs on iOS and Android, converts among more than 150 currencies, and uses a calculator-style input interface. The open-source project is built with React Native and Expo, making it a fit for privacy-minded users who prefer inspectable software and an ad-free experience.
There is one free plan, with no paid tiers described. Its practical feature set includes daily exchange-rate updates, cached rates for offline use, dark mode, and calculator input for entering amounts. The website states that the app contains no advertising or tracking. Offline caching is useful when traveling without dependable connectivity, while daily refreshes establish a clear limit for users who need intraday market data.
How Much In stays focused on core conversion rather than a wider financial toolkit. It does not provide conversion history or rate alerts, and its positioning does not include broader integrations. Deployment is mobile, with email listed as the support channel. Choose it for simple, private, open-source conversions on a phone, especially when offline access matters. Users who need historical analysis, notifications, continuously refreshed rates, or connected workflows should consider an app built around those capabilities instead.
