Dotori Currency Converter

Dotori Currency Converter turns one amount into every currency on your list at once. Type into any row and the rest follow — there is no "from" and "to" to set up, and no swap button to hunt for.

Your own currency stays pinned at the top and cannot be removed, so the number you care about is always in the same place. Everything under it is yours to add and remove.

Where the rates come from:

- The European Central Bank's official daily reference rates, fetched straight from the ECB
- If the ECB cannot be reached, the app falls back to ExchangeRate-API and says so on screen
- The rate date is always shown, and it is the date of the rates — never the moment they were downloaded

Key features:

- 30 currencies, all converted at once from whichever row you are editing
- Your main currency pinned at the top and always visible
- Add or remove currencies in Settings; tap another to make it your main one
- Decimals welcome — type 1,234.56 and the app keeps exactly what you typed
- Works offline: the last rates received are stored on your phone and keep converting
- Dark and light themes, Korean and English, portrait or landscape
- A keypad built into the app, so the system keyboard never covers your rates

About the numbers:

The ECB publishes once each working day, around 16:00 Central European Time. There is no update on weekends or holidays, so a rate date from a few days ago is normal — the app shows that date rather than pretending the value is newer than it is. While the app is open it re-checks about once an hour, and you can refresh by hand any time.

These are reference rates for information. Banks, card networks and exchange counters add their own margin and fees, so the amount you actually pay or receive will differ.

Privacy:

The amounts you type never leave your phone. The app asks the rate server for the whole table of the day and does the conversion on the device — neither the amount nor the currencies you picked are sent anywhere. There is no account, no login, and no developer server.

This version uses the Google Mobile Ads SDK to show a banner at the top of the screen, kept clear of the controls. There are no interstitial ads. Where regional consent is required, ads are requested only after consent is granted, and privacy options can be reopened from Settings.
