FINX vs CryptoFin Calculator

Покупай продавай акции рынка США в один клик

Convert any amount between cryptocurrencies and world currencies at live rates — and always know how fresh those rates are. WHY THE AGE OF A RATE MATTERS Most apps show you a number. This one shows the number and its age. When a source stops responding, you see it immediately — not an hour into trading on yesterday's price. The distinction is deliberate: a healthy state is left uncoloured, and colour appears only when a figure can no longer be trusted. A European Central Bank rate after the weekend is legitimately old — that is a caution, not a failure, and the two look different. EXACT TO EIGHTEEN DECIMALS Not a single operation on money uses floating-point arithmetic. The value stays exact from the exchange to your screen. On small crypto amounts that is the difference between a real number and a rounded zero. WORKS WITHOUT A CONNECTION The latest rates are stored on your device. Convert an amount on a plane or underground, and the app will tell you plainly that the rate is not fresh. WHAT'S INSIDE • Cryptocurrencies from Binance, with Kraken as a fallback source • World currencies from the European Central Bank • Updates once per second over a persistent connection • Rate history and a chart for an hour, a day, a week or a month • Your last ten calculations, kept on the device • Five languages: English, German, French, Italian, Russian • Light and dark themes, following your phone or chosen manually COLLECTS NOTHING ABOUT YOU No sign-up. No analytics. No advertising. No tracking libraries. The only permission the app requests is network access — without it there would be no rates to show. Your calculation history stays on your phone and is never sent anywhere. The server does not know what you converted: the conversion happens on your device.
