Currency Converter - Centy

USD to EUR to JPY in one screen. Scan a price tag with your camera and see it in your currency. Custom rates for any combination. Glance at live rates on your wrist. 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.

Apple Watch app (new in 1.4):
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 get current pairs in your Smart Stack and watch face complications.

Historical rate charts:
30-day, 6-month, and 1-year charts for every pair. See where a rate has been before you act on where it is.

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.

Widgets on iOS and watchOS
- iOS Home Screen rate widget with 7-day trend
- iOS calculator widget — convert without opening the app
- Watch face complication for your favorite pair
- 1-month history widget in the Smart Stack
