Sponsor's own description

This is a randomized controlled trial designed to assess the efficacy of a novel smartphone application as an automated reminder tool in improving the quality of bowel preparation for patients undergoing outpatient colonoscopies. The investigators will be comparing the smartphone application to traditional instructions for bowel preparation. The quality of bowel preparation will be assessed using the Ottawa and Aronchick bowel preparation scales.
