App and diet combo aims to improve colonoscopy cleanout

This study tests whether using a smartphone app and a prepackaged low-residue diet helps people get a better bowel cleanout before a colonoscopy compared to standard paper instructions and self-managed diet. The trial will include 420 adults who have never used the specific bowel prep medication Bowklean or haven't had a bowel prep in the last three years. The goal is to see if the app-based approach leads to a cleaner colon, which can help doctors find polyps more easily.
