The CurrencyMemory

The CurrencyMemory is an offline log for storing your own manually entered currency rates, like a personal notebook for remembering prices you encounter: the rate at an exchange booth, a store receipt in foreign currency, a number you want to keep for later. The interface resembles a calm pocket travel notebook — soft grids, thin separators, and small numeric slots. To add a memory, you pick the currency code, enter the observed rate or price, add a place (“airport kiosk,” “hotel exchange,” “street board”), and timestamp. Entries appear as tidy tiles ordered by time. In the overview, you can group memories by currency to see how manually logged numbers compare. The Rate Strip feature aligns all entries of a single currency into a narrow horizontal band, showing your personal history of prices without any external data.
