ABSTRACT=<sec id="sec1"><title>Background and aims</title><p>Colonoscopy is an essential cancer screening tool; however, bowel preparation is a multifaceted process that involves several steps. Proper preparation is crucial for a successful colonoscopy in terms of diagnostic accuracy and procedural safety. We evaluated the performance of a smartphone application with bowel preparation instructions on individuals undergoing their first colonoscopy.</p></sec><sec id="sec2"><title>Methods</title><p>In this randomized, prospective, endoscopist-blinded study, participants were scheduled to undergo their first colonoscopy between January 2020 and January 2022. The study protocol was registered at Thai Clinical Trials Registry (TCTR20190928002). They were randomly assigned to the smartphone education application (APP) or the standard education (control) group. The Boston Bowel Preparation Scale (BBPS) score, polyp detection rate (PDR), and adenoma detection rate (ADR) were compared. Factors associated with excellent bowel preparation were also evaluated.</p></sec><sec id="sec3"><title>Results</title><p>In total, 119 patients (APP group, <italic>n</italic> = 57; control group, <italic>n</italic> = 62) underwent their first colonoscopy. The mean BBPS score and proportion of excellent bowel preparation (BBPS≥8) were significantly higher in the APP group than in the control group. Smartphone application-guided bowel preparation achieved a higher proportion of adequate and excellent bowel preparation scores, was associated with other quality indicators, and achieved the target ADR, cecal intubation rate, and adequate withdrawal time.</p></sec><sec id="sec4"><title>Conclusion</title><p>This application may be a user-friendly option to improve the first-time colonoscopy experience, resulting in effective screening of colorectal cancer.</p></sec><sec id="sec401"><title>Clinical trial registration</title><p>The study protocol was registered at Thai Clinical Trials Registry (TCTR20190928002).</p></sec>
