ABOUT THE RATES
Kaeru uses a public exchange rate feed that publishes once a day. Rates are refreshed daily and stored on your device, so the app keeps working without a connection. They are reference rates for travel and everyday price checks, not trading rates.
WHY PEOPLE USE KAERU
Kaeru is built for travel, daily money checks, and quick price comparisons. The app is free to download and stays ad-free. If it helps you, you can leave an optional tip in Settings.
Download Kaeru and keep your exchange rates with you.
Ratings & Reviews

Version 2.3.0 takes Kaeru beyond the app:
- Home Screen and Lock Screen widgets keep your favorite pairs in view.
- Siri and Shortcuts: ask for a conversion without opening the app.
- Rate history charts for 7 days, 30 days and 1 year, so you can spot the trend before you exchange.
- Add your card or bank fee and see the amount you really receive.
- Share a conversion in one tap.
- A reworked onboarding gets your currencies ready from the start.
