About this app

Complex exchange rates, done in a single tap.

Exchange Calculator shows live rates at a glance and does the math you actually need before traveling, shopping abroad, or sending money. Minimal ads, maximum speed.

■ Two-way conversion
Put your "from" and "to" currencies side by side — type in either box and the other updates instantly. Swap both with one ⇅ tap. From USD, JPY, and EUR to Southeast Asian and Middle Eastern currencies, 32 in total.

■ Live rates, 32 currencies at once
See live rates and daily changes for major currencies on one screen. Drag your favorites into your own order — it saves automatically.

■ Overseas payment fee comparison (the key feature)
"Should I exchange cash, pay by card, or use a travel card?"
Just enter the amount you'll spend, and the app calculates the real cost and fees for all three, then tells you which is cheapest and how much you save.
· Cash exchange — real cost with your preferential rate applied
· Regular card — includes the telegraphic transfer rate + brand & overseas service fees
· Travel card — based on fee-free cards
The detailed report reveals the "break-even preferential rate" (the point where cash beats card), a rate-by-rate simulation, and real tips like avoiding the costly DCC trap when paying abroad. Every fee rate we apply — and its source — is shown transparently.

■ Travel money planner
Enter your travel budget in KRW and get how much it is in the local currency, plus your daily spending allowance. Trip prep made simple.

■ Reward Center
Check-in, daily missions, rate prediction, and coin leaderboard — all in one place, giving you a reason to come back daily. The main screen stays clean and focused purely on calculation.

■ Perfect for
· Anyone deciding how to exchange money before a trip
· Shoppers who want to cut fees on overseas purchases and subscriptions
· Expats, students, and traders who check rates daily
· Anyone tired of overcomplicated currency apps

Install now and start saving on fees from your very next payment.
