Tools and Currency Converter

The Tools page currently includes the currency converter.

Currency Converter​

The converter lets you:

  • enter an amount
  • choose source and target currencies
  • swap source and target
  • pick quick target currencies (USD, GBP, CHF, JPY, CAD, AUD, SEK, PLN)
  • choose source and target from 20 currencies (all supported currencies except DKK)

The source currency initially follows your base currency setting, the target starts as USD, and the amount as 100. Choosing the same currency in both fields swaps them.

Exchange Rate Behavior​

The converter uses the same rates as all totals in the app (the rates loaded in your Settings context), not a separate request. The server uses EUR as the base, refreshes stale cached data from the Frankfurter API, falls back to stale database rates when the API is unavailable, and finally falls back to built-in rates if no cache is available.

Converter results are informational. Saved transactions keep their own amount, currency, and exchange rate metadata at booking time.
