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.

If it helps you, you can leave an optional tip in Settings. Download Kaeru and keep your exchange rates with you.

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.
