## What is MyColo?

Life with IBD can be tough. But by joining a clinical study, you’ve taken an important step in managing a challenging condition for the better. COLO is an engaging app designed to track your symptoms, allowing you to provide daily feedback to your clinical study team about your IBD. By creating your own “color profile,” COLO can help you recognize trends to better manage your disease and get more from your clinical trial for IBD.

Once enrolled in a select IBD clinical study, you can use the COLO app to:

• track your spectrum of symptoms for the purpose of study research
• calculate your COLO color profile each day
• confirm when you might be in a flare state
• provide real-time feedback to your study site
• receive daily data and important messages 
• find out how other COLO app users are feeling
• collect awards for your continued participation 
• get important study site contact information

COLO keeps you engaged with your clinical study. Each day you sign-in, you’ll unlock a new shape with which you’ll build your own avatar and collect awards for staying active. While we know IBD is serious business, the new COLO app is a fun way to stay connected to your trial, track how you’re doing, and help you provide valuable information to your study team.
