Change You Can Believe In is a coin collector concept that represents your savings in tangible things. It automatically logs the change you drop in, everyday.
Customized trinkets represent items you save for. Simply place a trinket on the dollar sign to see how your savings add up. And it's easy to add a new trinket.
