The Currency Converter That Keeps Working in a Dead Zone

Field notes

The page describes a local-storage workflow: conversions continue from cached data, while a visible timestamp identifies how old each rate is. It covers 155 currencies, searchable by code or name, and includes a seven-day closing-rate sparkline for each pair. Rates are identified as mid-market reference figures refreshed roughly every six hours; the site cautions that banks and bureaux de change add their own spreads and fees.
