Currency Converter

CBR & market rates: my currency, favorites, offline cache, daily summary
New in version 0.6.8
The About screen now has an "Our projects" section linking to 3X-UI Manager, the 3x-ui manual and netadm.pro. The developer website link now points to yukh.net. Catalog builds explain that updates come through F-Droid.
💱 A simple, fast currency converter using rates from the Central Bank of Russia (CBR) or market (mid-market) rates.

Available in English and Russian (follows the system language).

Features:
• Two rate sources — 🇷🇺 CBR and 🌐 market (mid-market) rate.
• All CBR currencies, including less common ones.
• "My currency" — a persistent home currency the summary is computed against.
• Favorites: search by code, name, or country.
• Convert from your currency or any other: the source currency can be switched temporarily without changing settings.
• Friendly format for cheap currencies: "100 RSD = 73 RUB" instead of fractions.
• Rates are cached and work offline between updates.
• Rate summary notification with your favorite rates — it arrives as soon as the source publishes a new rate; tapping it opens the summary. Rate changes are shown next to each rate.
• Rate date and last refresh time always visible.

No ads, no sign-up, no personal data collection. All settings stay on your device only.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
