Currency converter using the camera to read prices and converts them from one currency to another.
If some of the numbers can't be recognized the user can easily add these as training images to the OCR-engine. Next time the app is synced with the server the images will be shared with all users.
At the bottom of the list of currencies there is a "Add new..." item. Use this to add custom currencies with exchange rate to any of the available currencies (will be recalculated against Euro)
In the textbox in the main screen you can manually enter a price if the OCR can't recognize the numbers.
