My IBD Tracker

Living with Crohn's disease or ulcerative colitis means paying attention to a lot of moving parts — what you ate, how you slept, where you were, how stressed you felt, and whether any of it mattered. My IBD Tracker gives you one calm, organised place to capture all of it, and the tools to start spotting what's actually going on. I built this app because I have ulcerative colitis and needed something that tracked the right things without getting in the way. Personally, I only log new meals, snacks or drinks rather than every single one — but the app supports whatever approach works for you, including saving favourites and quickly reusing recent entries. What you can track Bowel movements — stool consistency on the Bristol scale, urgency, blood and mucus indication Cramps — pain level (1–5), location (left, centre, right), and optional duration Meals, snacks and drinks — with fully customisable trigger lists so you can flag whatever you suspect, optional photos, favourites and quick reuse of recent entries Daily check-in — day type, location, stress level, energy level, and activity impact, plus an optional reminder Environmental signals (experimental) — optional barometric pressure and temperature capture, to explore possible links with your symptoms Sleep and heart rate — Apple Health sleep duration, wake events, resting heart rate and HRV, pulled in automatically for context alongside your symptoms On your Apple Watch Log bowel movements and cramps from your wrist — quick, discreet, and synced straight back to the app. How it helps you understand your data Home — your current state and a Bowel Pattern Score comparing today with your own baseline History — every event for a day on one scrollable timeline, with your check-in summary at the top Patterns — symptom trends across 7, 30 or 90 days, with active phase threshold line, energy and stress overlays, time-of-day and weekday views, location-based pressure data, and sleep and heart rate charts mapped against your active phases Trigger breakdown — compare bowel movements and cramps by day type, location and food trigger — same day and next day Reports — a clinical PDF covering bowel movements, cramps, stress, energy, an exploratory environmental signals section, and sleep analysis and heart metrics sections, ready to share with your consultant Designed for real use One-tap logging from the home screen — each tile shows your last entry and opens the log form Home Screen and Lock Screen widgets — Quick Log and Today's Summary Larger analysis screens on iPad, with sidebar navigation Works without an internet connection Active phase threshold you set yourself I built this for myself first, so everything is customisable to match real life. If something's missing, confusing, or could work better for you, I genuinely want to hear about it — this app grows from real feedback, not guesswork. And if it's helped you make sense of your IBD, a review means a lot and helps other people managing the same thing find it too. A note on the experimental features The environmental tracking (pressure and temperature) is based on reading research articles exploring possible links with IBD flares. Sleep and heart rate data from Apple Health are included for broader lifestyle and recovery context, not to assess health status or explain IBD activity. None of these are clinically established triggers, and each is clearly marked as exploratory throughout the app and in reports. Apple Health data is read for on-device analysis only — nothing is written back to Health. It's all there for you to investigate your own patterns — not to replace clinical advice. The Bowel Pattern Score is a comparison with your own baseline, not a diagnosis or flare prediction. Important This app is intended solely as a personal tracking and communication aid. It does not provide medical advice, diagnosis, treatment, or emergency assessment. Always consult your clinical team about your symptoms and treatment.
