This app has a lot of potential. There's some extremely useful information on Crohn's disease, hepatitis B, microscopic colitis, and screening colonoscopy guidelines based on prior polypectomy pathology. What I would like to have added to the app would be: hepatitis C guidelines, ulcerative colitis guidelines, recommendations of one to restart blood thinners after polypectomies, and Cirrhosis evaluation and management. The app is good, with a little work - it could be phenomenal.
