How to get started

1) Install the App or sign up online

Download the RoundUp App for iPhone or Android or use the Web Version, all completely free.

2) Create Your Account

Enter your name and email address, and choose us as the organization you want to support.

3) Link Your Credit or Debit Card

Create a secure, read-only link with your card. Your data is safe: we use the exact same API as Venmo and Acorns.

A Word on Security

The RoundUp App can never see your full credit card number. The card number is sent directly to Stripe, our payment processor. Stripe also does processing for Facebook, Amazon, and 100,000 other organizations in the US.
