Multi-currency calculator
Convert between several currencies at once — for example AED, USD and EUR on one screen — with the rate for every pair shown underneath.
A currency calculator for the whole world
Impex is an iPhone app for people who trade across borders: a multi-currency calculator, live market quotes and sea freight rates in one place. 160+ currencies from a free global feed, any base currency and an offline mode.
The task
Currency apps tend to be either cluttered with ads or tied to one country’s central bank. Impex had to be fast, private and useful anywhere in the world — including on a plane with no connection.
What we did
Market quotes
EUR/USD and other pairs, gold and silver, Bitcoin, Ethereum and USDT on one screen, with the daily change and a marker that the data is current.
Freight rates
Sea freight by route — Baltic, Black Sea and more — in USD or EUR per tonne, made for grain and oilseed traders.
Offline, in 10 languages
The last rate snapshot is cached on the device, and the app speaks 10 languages, including Arabic with a full right-to-left layout.
