This financial app is based on OANDA’s exchange rates, which OANDA, an Internet financial company, filters from auditing firms and banks. The rates are averaged and updated daily. You can choose the Interbank rate or use the percentage add-on feature to calculate typical rates charged by credit card companies and banks. It’s a simply designed app for a specific function, and the best part: It’s free.
This app has a stellar scrolling search function in which the letter of the currency you’re scrolling through pops up when you use the scroll bar. This is great, so you don’t get a headache staring at the more than 190 currencies listed in this app. You can also use the app to convert four precious metals: gold, palladium, platinum and silver. A handy “Send to a Friend” button allows you to email conversions quickly to business associates and the like.
Other currency-conversion apps use flags from each country as a visual for searching for a particular currency, which could be used here to visually enhance the search. But, overall, the design of the OANDA Currency Converter is clean and intuitive.[appbox googleplay com.oanda.currencyconverter]
