CurrencyPals is a currency converter for travel. Every row is an input, so you type an amount in whichever currency you have and see all the others at once. Rates are cached on the iPhone, so it still converts on a plane or on a SIM that has not connected yet. ## Links - page: https://superduperai.co/products/currencypals/ - site: https://fortunto2.github.io/currencypal/ - app_store: https://apps.apple.com/app/id6759005730 - github: https://github.com/fortunto2/currencypal - privacy: https://superduperai.co/products/currencypals/privacy/ - support: https://superduperai.co/products/currencypals/support/ ## Features - **Any row is the input.** Tap any currency and type; every other row recalculates through a USD pivot.

They refresh automatically when older than 4 hours, and a badge shows their age and turns orange after 4 hours. - **31 currencies plus 5 cryptocurrencies.** 30 ECB currencies and the ruble, plus Bitcoin, Ethereum, Solana, XRP and BNB. - **30-day chart.** Tap a currency name to see a 30-day chart for the pair with high, low and change. - **Your own list.** Add currencies by code or name, drag to reorder, swipe to remove. ## FAQ ### Does it work without internet? Yes, after it has loaded rates once. Rates are cached on the phone and conversion runs locally. The badge at the top shows how old the rates are. ### Where do the rates come from? European Central Bank reference rates via Frankfurter for 30 currencies, open.er-api.com for the ruble, CoinGecko for the five cryptocurrencies. They are reference rates: a bank or exchange office adds its own spread and fees. ### How often do rates update? Automatically when the cached rates are more than 4 hours old, and any time you pull the list down. ### Which currencies are supported? 31 currencies (30 from the ECB list plus the ruble) and Bitcoin, Ethereum, Solana, XRP and BNB: 36 in total. ### Do I need an account? No. There is no sign-in and no ads.
