Currency Converter - Centy

USD to EUR to JPY in one screen. Scan a price tag with your camera and see it in your currency. Get an alert when a rate hits your target. Glance at live rates on your wrist or Lock Screen. Most currency apps don't do any of this. Centy does all of it.

Scan prices with your camera:
Point Centy at a price tag, receipt, or restaurant menu. Live Scan reads the number instantly and overlays the converted amount on your screen. No typing, no copy-paste. Just point and read.

Multi-hop conversions:
Every other currency app does A to B. Centy does A to B to C to D in one view. Plan a multi-country trip, route a wire transfer through an intermediate currency, or compare margins across markets without juggling tabs.

Rate alerts:
Pick a pair, set a target rate or a percentage move, and Centy notifies you when the market gets there. Perfect for timing a transfer or a trip.

Apple Watch app:
A real watchOS app, not a glorified complication. Convert on your wrist, browse rate history charts, customize standard rates for the conversions you do most, and keep your favorite pairs in your Smart Stack and watch face complications. Your iPhone's default pair and favorites sync to the watch.

Historical rate charts:
See where a rate has been before you act on where it is. Low, high, average and change for the period, and drag across the chart to see the rate on any day.

Custom exchange rates:
Lock in what your travel card actually gives you, what your bank charges, or your contracted vendor rate. Centy is built for the messy reality of money, not just the mid-market quote.
