Find out what your gut actually reacts to
Clairop is a symptom and food tracker for Crohn's disease, ulcerative colitis and IBS. Log in seconds, find the pattern even when the reaction lands three days later, and walk into your appointment with something worth reading.
The problem
Reactions don't arrive with the meal
Thursday's flare can trace back to Tuesday's dinner. Most food diaries assume cause and effect happen in the same sitting, so people log for a week, find nothing, and stop. Clairop checks three delay windows out to three days.
How Clairop works
01
Log a movement in one tap
Tap the Bristol type and you're done. Urgency, blood and overnight are one toggle each, only if you want them.
02
Say what you ate
Describe the meal the way you'd say it out loud. It's turned into foods you check before anything is saved.
03
Or scan it
Photograph the plate, scan the barcode, or scan the ingredients label on the pack. If the database has no ingredients for it, the app says so rather than guessing.
04
See exactly what's in it
The load by subgroup, the ingredients that drove it, and the source for every value. No data reads as no data, never as safe.
What's in the app
One subscription, everything included: logging, the assistant, photo scanning, trigger analysis and the report for your doctor.
01
One day, in full
Your activity score broken into its items, then every meal logged, each with its FODMAP verdict.
02
Every day, kept
Score, movements, meals and pain, day by day, for as long as you have been logging.
03
Likely triggers
Ranked, with the delay window and how many meals each one rests on, so you can see how sure it is.
04
The GI visit report
One page a gastroenterologist can read in a minute, with where each number came from stated above it.
05
Ask, or log by chatting
Ask whether a food is high FODMAP, or log a meal or a movement in plain words. It answers with your own logs in view. Optional, and only on once you agree to it.
Delayed-reaction trigger analysis
Three delay windows out to three days, corrected for the hundreds of comparisons run at once.
FODMAP scanning, working shown
All six subgroups, each value with the paper it came from. Unknown reads as “no data”, never as low.
Disease activity scores
Harvey-Bradshaw Index for Crohn's, PRO-2 for colitis, from answers you have already given.
A report your doctor can use
One page of the numbers a gastroenterologist asks for, provenance stated above the figures.
Built for these, specifically
Crohn's and colitis are not IBS. Clairop asks which one you have and changes what it measures.
- Crohn's disease
- Flare timeline, days with blood, overnight episodes and medication adherence, scored the way the 1980 index scores them.
- Harvey-Bradshaw Index
- Ulcerative colitis
- Rectal bleeding and stool frequency against your own baseline, so a bad week is measured against your normal, not a textbook's.
- PRO-2
- IBS
- Trigger analysis for IBS-D, IBS-C and IBS-M, testing every food at under six hours, six to twenty-four, and one to three days.
- Three delay windows
- Low FODMAP
- Barcode scanning broken down by fructans, GOS, lactose, fructose, sorbitol and mannitol, then reintroduction once elimination is done.
- Six subgroups

Why trust it
We show our working
Clairop has no regulatory clearance and no medical-body endorsement, because it neither diagnoses nor treats and does not qualify as a device. A certification would ask you to trust us. Instead the app lets you check us.
Read the method and sources- A citation on every FODMAP value, in the app, on the verdict screen
- The original papers behind both disease activity indices
- Omitted score items disclosed, and printed on the report itself
- The sample size shown on every trigger

Questions
What is Clairop?
Clairop is an iPhone app for people living with IBS, Crohn's disease or ulcerative colitis. It logs meals, symptoms and stool in seconds, looks for the foods your gut reacts to, including reactions that arrive up to three days later, and turns your logs into a one-page report for your GI appointments. It is made by Pavado Technologies Inc. in Ontario, Canada.
Is this a medical device?
No, and that is deliberate. Clairop records what you log, summarises it, and looks for statistical patterns. It does not diagnose, does not treat, does not recommend or adjust medication, and takes no measurement from your phone's sensors. It has not been evaluated by the FDA, MHRA, Health Canada or the TGA, because it does not need to be.
How do I know the FODMAP data is right?
Every value in the app shows the paper or database it came from, and you can read the list on the Method page. We are not affiliated with Monash University and we do not use their data or their certification mark. Where an ingredient is not in our reference table, the app tells you that instead of assuming it is low.
Why does it sometimes say it doesn't know?
Because it doesn't. Correlation needs both the days a food showed up and the days it didn't. Below five of each, anything we showed you would be a coin flip with a confident label on it, so we show the count instead and keep waiting.
What happens to my data?
Your entries sync to your account so they survive a new phone. Meal photos stay on your device and are never uploaded to our servers. When a photo is sent for food identification, nothing identifying you travels with it: no name, no email, no account ID and none of your symptom history. The assistant is optional and works differently: what you tell it, plus a short summary of your recent logs, goes to our AI provider so it can answer, still without your name, email or account ID, and only after you agree to that in the app. You can export or permanently delete everything from the app.
Is it free to download?
The download and the setup questions are free. Using Clairop after that needs a Clairop Pro subscription, weekly, monthly or annual, and it includes everything: logging, the assistant, photo scanning, trigger analysis, the GI visit report and your full history. The App Store shows the price in your currency before you subscribe. Your data stays yours either way: you can export or delete it without a subscription.
