Track symptoms, meds, and bowel movements. Export clinical reports for your doctor. Your data stays in your own Google Drive, OneDrive, or iCloud — never on our servers.
Colitis Tracker is the clinical symptom log built for people living with Crohn's disease, ulcerative colitis, IBS, and other digestive conditions — designed to give you and your gastroenterologist the data that actually matters.
YOUR DATA STAYS YOURS
Everything you log lives in your own Google Drive, OneDrive, or iCloud — your choice. Colitis Tracker never stores your health information on our servers. No subscriptions. No data mining. No cloud you don't control.
WHAT YOU CAN TRACK
- Daily symptoms — rectal bleeding, abdominal pain, fatigue, bloating, nausea, tenesmus, and more
- Bowel movements — individual events with time and Bristol Stool Scale type
- Medications — daily adherence plus infusion and appointment tracking for scheduled treatments
- Food triggers — see which foods correlate with your symptoms
- Menstrual cycle (optional)
- Weight — synced with Apple Health
- Mental wellness — optional PHQ-9 depression and GAD-7 anxiety screenings, prompted every two weeks
PATTERN INSIGHTS
The built-in insight engine analyzes your last 30–90 days of data on your device and surfaces patterns you might miss: flare frequency, Bristol trends, food correlations, and more. Everything computed locally — nothing sent anywhere.
SHARE WITH YOUR DOCTOR
Export a full PDF or CSV report covering any date range. Reports include a symptom summary, medication adherence, bowel movement trends, food correlations, mental wellness history, and an insight summary — formatted for your care team.
APPLE HEALTH
Colitis Tracker reads and writes to Apple Health automatically — weight, bowel events, GI symptoms, and more.
REMINDERS
Set daily logging reminders, medication alerts, and mental wellness nudges so nothing falls through the cracks.
ABOUT COLITIS TRACKER
Colitis Tracker started in 2014. It was built for a registered nurse living with Crohn's disease who needed a clinical record she could actually hand to her doctor. The app has been completely rebuilt from the ground up — available on any device, with the same focus on privacy and clinical utility it was founded on.
Free to use. No subscription required.
Colitis Tracker has been completely rebuilt from the ground up with a new design, Google and Microsoft sign-in, Sign in with Apple, iCloud storage, Apple Health integration, pattern insights, mental wellness check-ins, and PDF/CSV reports.
