Do I Need That provides tools to help you make better choices with your money. Do I need That can show you how much you could save and how much that money would be worth in the future if you saved it today.
Do I Need That helps to increase the emotional friction associated with online shopping by showing the money your spending, and what it will mean in the long term. It automatically launches for over ten different online eCommerce sites and can be manually activated as well.
Research indicates that consumers spend significantly more money when using a card over cash because there is a lack of emotional friction. This tool is designed to help raise the level of emotional resistance to make budgeting easier.
