RateKey: Currency Converter

Type it on your home screen. RateKey puts a currency converter widget with a real number pad on your home screen. See a price tag, type the amount on the widget keypad, and read the result on the spot — without opening the app. Tap a currency chip and the keypad turns into a currency grid, so you can switch pairs right there too. CONVERT ON THE HOME SCREEN • A widget with a built-in number pad — type 1200 and see it converted instantly • Switch currencies on the widget: 11 frequent currencies plus quick access to all of them • Works offline with cached rates, clearly marked with the update time OPEN STRAIGHT INTO THE CONVERTER • The app opens on the converter. No feeds, no promotions, no detours • Flip the pair with one tap; amounts format cleanly as you type • A rates board converts one amount into all your currencies at a glance READ THE TREND BEFORE YOU EXCHANGE • Charts from one week to five years • Press and hold to read the exact rate on any day SEARCH THE WAY YOU SPEAK • Find currencies by code, English or Chinese name, or everyday words — "dollar", "yen", "rmb" • Onshore CNY and offshore CNH are listed separately — they are two different prices KNOW WHERE YOUR RATE COMES FROM • Every number shows its source and update time • Rates are mid-market reference rates from openly published data (Frankfurter), updated daily • They are not a bank's buy/sell counter rates — we say so right under the result WHAT RATEKEY DOESN'T DO • No ads. No account. No sign-in. • No money transfers, no wallets, no crypto trading • No location permission — your home currency is inferred from system settings only 40 everyday currencies for travel and cross-border life: USD, EUR, JPY, CNY, CNH, GBP, HKD, TWD, SGD, KRW, THB, AUD, CAD, CHF, MYR, VND, IDR, PHP, INR, AED, TRY, SEK, NOK, DKK, PLN, MXN, BRL, NZD, ZAR and more.
