About
Know what you actually spent abroad.
Paying in dollars, doing math in yen — the numbers stop meaning
anything. Sseotji shows the amount in your home currency using
that day's rate, right as you type it.
No clutter. Write it down, see it, done.
■ 13 currencies

■ The rate from that day
Official rates from the Export-Import Bank of Korea.

Tap a day to see what you spent. This month's totals sit

you to your other devices.
