WithMe is an app that helps overwhelmed cancer patients connect to coordinators who can help them find relevant clinical trials.

Patients + coordinators = 👍

The problem: clinical trial enrollment

Using Marvel, I made a simple clickthrough prototype (limited functionality) from the screens designed in Sketch. I led our participants through scripted in-person user testing, took notes, and recorded the sessions for review later.

Findings & conclusion

Our goal at the outset was to improve the patient experience in clinical trials matching. We believed an app could help accomplish this, and that seems to be true! Additionally, a few findings in particular stood out:

  • If you’re not careful, interfaces can get in the way of users who want to get to things faster.
