About this app

Wave Rate is a live currency converter for 160+ world currencies — built for travellers, expats, and anyone who checks exchange rates every day.

WHETHER YOU'RE TRAVELLING OR AT HOME
Check live exchange rates before your flight, convert currencies on arrival, or keep an eye on the dollar rate from your sofa. Wave Rate gives you everything in one place — no clutter, no distractions.

TRACK WHAT YOU SPEND ON A TRIP
New: create a trip and log what you spend in the local currency. Every expense is converted to your home currency at the exchange rate of the day you spent it — so yesterday's dinner keeps its price when the market moves.
• Create a trip with its own home currency
• Add each expense in the currency you actually paid in — baht, lira, dong, anything
• See the trip total in your own money, grouped by day
• Trip expenses work offline: add them on the plane, and the missing exchange rates fill in by themselves once you are back online
