Exchange Rate Alert & Widget

Exchange Rate Alert has been completely rebuilt — faster, more accurate, and easier on the eyes.

■ Live exchange rates
· Live quotes for 58 currencies against the Korean won — USD, JPY, EUR, CNY and more
· Besides the base rate, see all four bank prices at a glance: cash buy/sell and wire send/receive
· Mini sparkline charts and daily change indicators
· Build your own board with just the currencies you care about

■ Target-rate alerts (fully redesigned)
· Get a push notification the moment a rate hits your target
· Our server now watches the market 24/7 — alerts arrive reliably even when the app is closed, unaffected by battery optimization
· Set alerts on the base rate or on cash/wire prices
· One-time or repeating alerts, with quick ±0.5% / ±1% presets
· Optional weekday morning briefing and sharp-move notifications

■ Currency calculator
· Convert several currencies on one screen at the same time
· Decimal amounts supported
· Tap any currency to make it the base
· Your last amount is saved automatically

■ Detailed charts & 52-week range
· Rate charts from 1 week up to 3 years
· See where today's rate sits against the 1-year high and low
· Calculate real exchange prices with your bank's preferential (fee discount) rate

■ Home screen widgets
· Check rates right on your home screen without opening the app
· Shows one currency or a four-currency list depending on widget size
· Adapts automatically to light/dark mode

■ Dark mode
· Follows your system setting, or set it manually

Note for existing users: the app has been fully redesigned, so alerts created in previous versions need to be registered again.
