Log it fast, find the pattern, prove it to your doctor
Log your symptoms in seconds, find out what your gut actually reacts to even when the reaction lands three days later, and hand your doctor a report worth reading.
Step one
Logging that takes seconds
The single most repeated complaint about food diaries is that they get abandoned inside a week, because logging every ingredient is tedious. Every decision in Clairop's logging flow comes back to that.
A bowel movement is one tap on the Bristol scale. Urgency, blood, mucus and whether it woke you at night are optional detail underneath. Symptom sliders use the exact wording and ranges of the clinical indices, so the app never asks you the same question twice to produce a score it could have calculated.

Step two
Know what's actually in it
Scan a barcode and Clairop pulls the product's ingredient list, then checks it against a reference table built from published food composition research. You get the FODMAP load broken down by all six subgroups, because tolerance is per-group: plenty of people react hard to fructans and are completely fine with lactose.
Every value shows the paper it came from. Where an ingredient isn't in our table, the app says so rather than assuming it's low, because telling someone a food is safe when we don't know is the one mistake here that can actually hurt them.

Step three
Patterns that hold up
Gut reactions arrive late. Clairop tests every food you log against three delay windows: within six hours, six to twenty-four, and one to three days.
For each, it compares symptom severity after meals containing that food against meals without it, and reports the effect size alongside the result. Because hundreds of comparisons run at once, the results are corrected for false discovery. Without that correction, testing 200 foods across three windows would throw up roughly 30 false triggers by chance alone, and every one would be presented to someone as a food to avoid.
Nothing is shown until there are at least five meals with the food and five without. Below that, the app tells you the count and keeps waiting.
Onion
Symptoms ran worse one to three days after onion, across 14 exposures.

Step four
Something to take to your appointment
For Crohn's, Clairop calculates the Harvey-Bradshaw Index. For ulcerative colitis, PRO-2. Both from answers you have already given, both named, and both with the items that need a physical examination left out and that omission stated on the score.
The report itself is one page: score trend, mean movements per day against your own baseline, days with blood, overnight episodes, medication adherence, lab results and confirmed triggers. Its provenance sits above the numbers rather than in a footnote, so a clinician reading top-down knows before they reach a single figure that this is patient-entered data.

The index puts that in its remission band.
A questionnaire score from your own answers, not an assessment of your condition.
Everything cites its source
Clairop has no regulatory clearance, because it neither diagnoses nor treats. What it does instead is show its working, so a sceptical gastroenterologist can check the arithmetic and read the papers.
