CUCO Currency Converter

Convert 166 currencies, Bitcoin, gold and silver — and keep converting when the signal drops. CUCO is a currency converter and travel money app: exchange rate charts, rate alerts, a trip budget and a bill splitter, with no account and no sign-up. WHO IT'S FOR Travel, converting USD to IDR without internet, and splitting bills with friends. CURRENCY CONVERTER Pick two currencies, type an amount, read the answer. A big keypad, a searchable currency list, and a one-tap swap. Recent pairs stay where you left them. YOUR OWN EXCHANGE RATES LIST Save the currencies you actually use. Type one amount and the whole list converts at once, each currency showing its own exchange rate. Add, remove and reorder freely — the list is yours and it is remembered. EXCHANGE RATE CHARTS See where a rate has been over 10 days, 1, 3 or 6 months, 1 year or 2 years, with the period high, low and percentage change at a glance. Where real history is not available for a pair, CUCO says so instead of drawing a made-up line. THE REAL RATE AFTER FEES Banks, kiosks and exchange counters take a cut. Enter the percentage and see what you will actually receive, right next to the mid-market rate. EXCHANGE RATE ALERTS Set a target above or below today's rate and CUCO watches that currency pair for you, with a progress bar showing how close it is. A notification arrives when the target is hit — useful for booking, sending money home, or timing a transfer. TRAVEL BUDGET AND EXPENSE TRACKER Create a trip, set a budget, and log each expense in the local currency as you spend it. Every expense stores the exchange rate from the moment you recorded it, so your totals never quietly change when rates move. See spending by day and by category, and export the whole trip to CSV when you get home. SPLIT THE BILL Divide a restaurant bill evenly, or itemise it: enter the dishes, tap who shared what, and everyone gets their own figure. Service charge and tax are applied the way the receipt actually charges them, so the total matches what the restaurant asks for. A tip field is there when you want it. CASH WALLET Track the notes and coins in your pocket across every currency at once, totalled in the one currency you think in. CARD, CASH OR ATM ABROAD Enter the rate on the exchange board and your card's foreign transaction fee, and see which option actually leaves you with more money. It also carries the one tip that saves travellers the most: when a card terminal or ATM offers to charge you in your home currency, decline it and pay in the local currency. WORKS OFFLINE An offline currency converter earns its place exactly where the data does not reach: aeroplanes, ferries, border towns, basements. CUCO caches the last exchange rates it downloaded and keeps converting without a connection. Every screen shows the time its rates came from, so you always know how fresh they are. TWELVE THEMES Twelve colour themes, light and dark, each checked for readable contrast. The app follows your system text size, so nothing needs squinting at. ABOUT THE RATES Honesty beats marketing here. Fiat currency rates come from free public data and update once a day — not every second. Bitcoin, gold and silver refresh roughly every sixty seconds while the app is open. Every screen states when its rates were published. Rates are for reference and will differ from what a bank, airport kiosk or exchange counter offers you. PRIVACY No account, no sign-up, no location permission. Your rates list, alerts, trips and expenses stay on your device. Currencies include USD, EUR, GBP, JPY, CNY, AUD, CAD, CHF, SGD, HKD, KRW, INR, IDR, MYR, THB, VND, PHP, TRY, AED, SAR, ZAR, BRL, MXN and 140 more, plus BTC, gold (XAU) and silver (XAG). Whether you are travelling, shopping on an overseas site, sending money home or watching the gold price, CUCO is a currency converter that tells you where its numbers came from and when.
