Microscopic Colitis OS is a clinician-built logging app for microscopic colitis —
collagenous and lymphocytic subtypes. Built by a practicing
gastroenterologist, it captures the symptom patterns and clinical anchors that make a
gastroenterology visit useful.
What you log:
• Stool frequency and watery consistency, nocturnal stools, urgency
• Subtype — collagenous vs lymphocytic
• Drug triggers — NSAIDs, PPIs, SSRIs
• Budesonide use and response
What you get:
• Today’s note: written from your answers, with a plan you can read line by line and the reason behind each line
• Symptom activity tracked over time
• For your next visit: what you recorded and the questions worth asking your gastroenterologist, on one page
• Premium: a one-page visit report for your doctor, symptom trends and CSV export
• A library on AGA-aligned microscopic colitis guidance, drug-trigger review, and
budesonide therapy
Privacy by design:
• All data stays on your device. No accounts. No cloud sync.
• No analytics. No ads. No data sale.
