MonoRate - Currency Calculator

Real-time currency converter with charts. 30 currencies, one tap.

You're at the airport, buying something online from overseas, or just curious how much that price tag is in dollars. MonoRate gets you the answer without fumbling through menus or waiting for pages to load.
Open the app, type a number, see the conversion. That's it.
We built MonoRate because every other currency app felt like it was designed by committee. Too many buttons, too many screens, too much going on. MonoRate does one thing and does it well.
What you get:
30 currencies USD, EUR, KRW, JPY, GBP, CNY, and 24 more. The ones people actually use when they travel or shop internationally.
A calculator that makes sense No tiny keyboard popping up over half the screen. MonoRate has its own full-size number pad. Type your amount, see the result update live.
Charts that tell you something useful Tap any currency to see how the rate has moved over the past 5 days, week, month, 3 months, or year. Good for figuring out whether to exchange now or wait.
Favorites Pin the currencies you check most. They show up right on the main screen so you're not scrolling through a list every time.
Dark mode Because staring at a white screen at 2am in a hotel room is nobody's idea of fun.
4 languages English, Korean, Spanish, and Chinese. The app follows your phone's language setting, or you can pick one manually.
No account required. No sign-up. Just open it and go.
