We're a small team and we read every message. The fastest way to reach us is e-mail:
We try to respond within 2 business days. When reporting a problem, please tell us:
Some currencies are not covered by the rate provider we're currently using, or the rate fetch failed. Pull to refresh, check your internet connection, or try again in a few minutes.
Rates are provided by CoinGecko (crypto) and Open Exchange Rates (fiat). They are updated periodically and cached for a short window to keep the App responsive. Real-world buy/sell prices at a bank or exchange will differ because of fees, spreads, and market conditions. The App is not financial advice.
Open the ⋯ menu at the bottom of the converter and choose Set manual rate. Enter your own rate and tap Set. A small "Manual rate active" badge will appear; tap Back to live rate in the same menu to restore the live rate.
Tap either currency card to open the picker, then tap the star next to any currency to favourite or unfavourite it. Favorites appear in their own section at the top of the picker.
Yes. The App does not collect personal data, does not require an account, and does not send any usage information off your device. The only network requests we make are anonymous queries to rate providers. See the Privacy Policy for details.
Open Settings → Language and pick System, English or Türkçe.
From Settings you can clear your favourites and reset any manual rate. To wipe all stored preferences, uninstall and reinstall the App.
Found a bug or have an idea? Drop us an e-mail with the details. We prioritise issues that affect many users and ideas that fit the App's calculator-first identity.
