Small Change, Big Changes


What if you knew you could help us to make a cancer-free world just by donating your spare change?

We want to let you know about a new program that allows you to do just that - donate your change to be the change.

How Does It Work?

The Round Up App allows you to automatically donate the change from your credit or debit card transactions to support the mission of the American Association for Cancer Research (AACR) to prevent and cure ALL of the more than 200 diseases we call cancer.

Once you create an account, you do not need to use the app while making a purchase. Just swipe your card as usual.

Make Giving Effortless

  • Provides a critical source of consistent support that allows us to do our work. This is true philanthropy.
  • The average donor ends up contributing $20-$30/month.
  • Naturally fluctuates up and down with your spending.

Security & Assurance

The Round Up App never has access to your credit card number. We use Stripe as our payment processor, the same company used by Facebook, Amazon, Lyft and 100,000 other companies.
