RateFlow is a clean, focused currency converter for daily conversions, shopping abroad and travel budgeting. Pin the currencies you care about, type an amount, and every currency updates together on one calm, readable screen. 150+ WORLD CURRENCIES From USD, EUR, GBP, JPY, CNY and HKD to regional currencies, RateFlow covers 150+ rates so your full travel or working list fits on one screen without leaving anything out. CONVERT EVERYTHING AT ONCE Pin your most-used currencies to the top. The moment you type an amount, all of them update in sync — no tapping back and forth between pairs. BUILT-IN CALCULATOR KEYPAD Work out a tax, tip, split bill, commission or order total right inside the amount field. Add, subtract, multiply and divide without leaving the converter to open another app. HOME SCREEN WIDGET Add the home-screen widget and read your rates at a glance. It refreshes automatically in the background and keeps the layout you arranged inside the app. QUICK SEARCH & ADD Search across 150+ currencies by name or code, or pick from the popular list with one tap. Any currency can be added, reordered or removed at any time. TUNED TO YOUR HABIT Switch between light, dark or system appearance to match your device. Export a backup of your currency list any time and import it back later — handy when you set up a new device. Amounts automatically use the right number of decimals for each currency (ISO 4217 — JPY none, USD two, BHD three), and the thousands and decimal separators track your device locale so large numbers stay easy to read. WORKS WHEN THINGS GO QUIET When the network drops, RateFlow falls back to the last rates it cached locally, so you can still check approximate values while offline. BUILT TO STAY READABLE RateFlow stays out of the way: large readable amounts, a calm layout, and only the tools you actually use every day — open the app and the answer is already there. Rates shown are estimates from public data sources and may differ from bank or market prices. ## Key features - 150+ world currencies - Convert all currencies at once - Built-in calculator keypad - Home screen widget - Quick search and add currencies - Offline access with cached rates - Customizable appearance ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Premium | $4.99 | one-time | ## Frequently asked questions about RateFlow ### Does RateFlow have ads?
