ConCurrency

The currency conversion app aims to provide users with real-time and accurate currency conversion rates using Google's open APIs. It will support a wide range of currencies and offer a user-friendly interface.

Fuctionalities

1. Currency Conversion: The core functionality of the app is to allow users to convert between different currencies. Users can enter the amount they want to convert, select the source currency, and choose the target currency. The app will display the converted amount based on the current exchange rate.

2. Real-Time Exchange Rates: The app will fetch real-time exchange rates from Google's open APIs to ensure accuracy. It should regularly update the rates to reflect the most recent changes in the currency market.

3. Favorite Currencies: Users can mark specific currencies as their favorites for quick access. The app will provide an option to save and manage a list of frequently used currencies.

4. Currency Comparison: The app will provide a side-by-side comparison of multiple currencies for easy analysis. Users can select multiple currencies and view their exchange rates simultaneously. Team Division:
