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 cleanse before a colonoscopy compared to standard paper instructions and self-managed diet. About 420 adults who have never used the bowel prep medication Bowklean will take part. The goal is to see if the app-based approach leads to cleaner colons and better detection of polyps.
