Food and symptom tags

Private by default
Logs stay on your iPhone. No account for everyday tracking, offline support, and a biometric lock when you want the app sealed.

Watch the pattern build
The log heatmap shows your rhythm. Stats break down type mix and timing after a couple of weeks of honest logging.
Bring data to the appointment
Read Doody’s Read, ask the chat what changed, or export CSV. Two to four weeks of logs beats “it’s been weird lately”.

Frequently asked questions
Everything you need to know about Doody as a poop tracker.
What is a poop tracker and why use one?
A poop tracker is a bowel diary on your phone. You record stool type (usually with the Bristol Stool Scale), time, and optional notes about food or symptoms. Over two to four weeks the log shows frequency and consistency patterns that are hard to remember accurately for a GP visit.
Learn more →How do I use the Bristol Stool Scale in Doody?
On New Entry, choose Hard (Bristol 1–2), Normal (3–4), Soft (5–6), Liquid (7), or None if you are noting a day without a bowel movement. The app stores the clinical type behind the friendly labels so your history stays comparable.
Learn more →Can Doody help me track IBS symptoms?
Yes. Log stool type every time you go, tag symptoms such as cramping or bloating, and tag foods you suspect. Stats and Doody’s Read surface mixes and correlations you can discuss with a clinician. Doody does not diagnose IBS.
Learn more →How do I find food triggers for gut issues?
Tag meals or categories when you log. After enough entries, Patterns may show lines such as a food group linked to soft stools in several logs. Treat those as hypotheses to test with your clinician or dietitian, not as proof of allergy.
Learn more →Can parents track a child’s bowel movements?
Doody Pro supports family profiles with separate histories. Use the same Bristol labels and notes you would bring to a paediatric appointment, and keep the biometric lock on if the phone is shared.
Learn more →What should I bring to a gastroenterologist appointment?
Two to four weeks of daily stool type and frequency, a short summary of urgency or pain days, foods that seemed to precede flares, and medicines tried. Export CSV from Doody Pro or screenshot Doody’s Read so you are not relying on memory in a short clinic slot.
Learn more →How do I track constipation and diarrhoea with one app?
Hard maps to constipated Bristol types; Liquid maps to diarrhoea. Logging both ends of the scale, plus None days, shows whether you lean IBS-C, IBS-D, or a mixed pattern across the same fortnight.
