## What is Koin?

Koin is the currency converter built for travelers who just want to know what something costs in their money.

Open the app, type the amount, see the result. That's it.

HOW IT WORKS
Set your home currency once during onboarding — the currency you think in. Then pick the currency of wherever you're traveling. Koin shows you the conversion in real time as you type.

FEATURES
• Instant conversion as you type
• 150+ currencies from every corner of the world
• Daily exchange rates, cached for offline use
• Swap currencies with one tap
• Searchable currency list — find by name, code, or country
• Comma or period decimal format — your choice
• Haptic feedback for a satisfying, tactile feel
• Clean, distraction-free design

BUILT FOR TRAVEL
Whether you're checking a price tag in Tokyo, splitting a bill in Berlin, or haggling at a market in Marrakech — Koin gives you the answer before the moment passes.

PRIVACY
Koin does not collect personal data. Exchange rates are fetched from ExchangeRate-API. Your currency preferences are stored only on your device.
