The Value of a PWA
arwConvert is a Progressive Web App (PWA). It provides a native app experience directly from your browser—meaning no app store downloads, no bloatware, and instant access to updates.
How to Install
- iOS (iPhone/iPad): Open arwConvert.com in Safari. Tap the Share icon at the bottom, scroll down, and tap "Add to Home Screen".
- Android: Open the app in Chrome. Tap the three-dot menu icon in the top right, and select "Install App" or "Add to Home screen".
- Desktop: Open the app in Chrome or Edge. Look for the install icon (a screen with a down arrow) on the right side of the URL address bar.
Why Install to Your Home Screen?
Installing arwConvert removes the browser URL bar for a clean, distraction-free interface. Most importantly, it locks in the app's offline caching, guaranteeing it will open instantly even when you are on an airplane or out of cellular range.
Mastering Your Rates
Mid-market API rates are great for baselines, but they rarely match the "street rate" you get at a physical currency exchange kiosk. arwConvert solves this by offering two distinct modes inside the settings panel.
Live Auto-Rate
When you need a general idea of global exchange rates, switch to Live Auto-Rate.
- Selecting a new currency pair from the dropdown automatically fetches the latest mid-market data.
- Rates are pulled from a secure, free API (Frankfurter).
- The input field locks to prevent accidental edits while in Live mode.
Manual Override (The Traveler's Best Friend)
When you are standing in a physical shop or kiosk, the real-world exchange rate usually includes a commission or markup. This is where Manual Override comes in.
- Switching to Manual Override unlocks the rate input field.
- Type in the exact exchange rate the kiosk is offering you (e.g., changing an API rate of 0.079 to a street rate of 0.075).
- The app stops trying to fetch data from the internet and strictly enforces your custom math.
- Your manual rate is saved locally so you can use it all day without resetting it.
Built for Travel
100% Offline Capable
Travelers frequently find themselves in dead zones, subways, or dealing with expensive roaming data. arwConvert is built with a sophisticated "Service Worker" that caches the application directly to your device.
- Instant Loading: The app will open immediately, whether you have 5G or zero signal.
- Retained Settings: Your last selected currency pair and manual rates are saved directly to your phone's local storage. If you lose connection, your math will still work perfectly based on your last saved settings.

- No accounts to create.
- No cloud databases tracking your conversion history.
- No API keys required to use the service.
