Stop guessing which foods hurt.

Yes. Logging meals, symptoms, medications, hydration and weight is free, and so is the community feed and your first comprehensive report after seven days of tracking. Premium is an optional subscription that adds unlimited doctor-ready PDF reports, advanced trigger detection, trigger-food alerts, barcode safe-or-caution scanning, community posting and care-partner access. You can cancel any time from your phone's subscription settings.

Every meal you log is an observation. You rate it fine, meh or nope, and can add symptoms on the same screen. Overnight, the app scores each food by how often it was followed by adverse evidence, counting the meals that sat fine in the denominator so a food you tolerate most of the time is not blamed for one bad day. Small samples are shrunk toward a prior so two coffees and two bad mornings read 'Possibly', not 'Very likely'. It is an association in your own self-reported data — a hypothesis to test with your care team, not a diagnosis.

It is built for inflammatory bowel disease generally — Crohn's disease and ulcerative colitis — and the same food-and-symptom logging works for IBS and other sensitive-gut conditions. The intake survey asks whether you are in remission, flaring, post-op or newly diagnosed so guidance fits your current state.

Meals with a three-point tolerance rating; symptoms including abdominal pain, urgency, diarrhea, blood in stool, constipation, bloating, nausea, fatigue, night waking, fever, appetite loss, joint pain, mouth ulcers and headache, each with a severity; medications and when you took them; hydration; weight; and lifestyle factors like sleep, stress and activity. You can also log a 'felt fine today' day, which is just as useful for ruling foods in.

Yes. The app generates PDF reports for a chosen period — seven days, thirty days or a custom range — with symptom trends, severity by time of day, tolerated foods, likely aggravators, medication history and hydration. You can print it or send it through your phone's share sheet before an appointment. Every report says on it that it is educational support, not medical advice.

Yes, optionally. When you turn Health sync on in Settings, the app reads weight, sleep, water and steps so reports reflect what you already track, and writes the weight and hydration you log back to Health. Nothing else is requested, and the permission prompt only appears when you enable the toggle.

Your entries are stored in your own account and are never sold or shared with advertisers. The community uses pseudonymous handles by default. You can export everything you have logged, and you can delete your account and all of its data from inside the app at any time.

No. Crohn's Food Tracker is a self-tracking and educational tool, not a medical device. It does not diagnose, treat or prescribe. Use what you learn from it as a starting point for a conversation with your gastroenterologist or IBD nurse, and seek urgent care for red-flag symptoms such as severe pain, persistent bleeding, high fever or signs of obstruction.
