What People Are Saying

Kate Rinder

I've looked at a number of different platforms and none of them have had the right tools and capacity for what we want to do. I'm excited that CitSci does!

CitSci is best-in-class. A powerful online platform for communities and community scientists to elegantly collect, manage, and analyze data with scientific integrity.

I'm not sure what I would do without CitSci. They make coordinating projects a breeze. I can manage my sites and assign volunteers all in the same place.
