The Monash app tells you what is in food; Clairop tells you what food does to you. That is why this comparison is less "which one" and more "which job". Monash University's team developed the low FODMAP diet and measures foods in its own lab, and its app turns that work into traffic-light serving sizes. Clairop does not measure food. It watches what you eat and how you feel, and looks for the foods that line up with your symptoms. We cover more alternatives, by job, in Monash FODMAP app alternatives.
Clairop is not affiliated with Monash University and does not use Monash app data.
Lab-measured data. Monash freeze-dries food samples, measures FODMAPs by liquid chromatography, and has a dietitian set the low, moderate and high serving sizes. No tracker, Clairop included, replaces that.
It is the reference for elimination. For the first phase of the diet, a trustworthy food guide, certified branded products, recipes and a structured reintroduction plan are what you need, and Monash supplies all of them. The diet itself has randomised trial evidence (Halmos 2014).
One payment, two platforms. A one-time purchase, 7.99 US dollars on the US App Store, with no subscription, on iPhone and Android. Clairop is iPhone only and needs a subscription.
Minimal data collection. The store listings report very little data collected.
Clairop logs meals, symptoms and stool in seconds, then looks for the foods your gut reacts to, including reactions that land days later.
It finds your own triggers. The Monash diary records what you ate and how you felt, but leaves the interpretation to you. Clairop compares symptom severity after meals with and without each food in three windows (under six hours, six to twenty-four hours, one to three days), corrects for false discoveries, and waits for five meals of each before reporting. That matters most in reintroduction and afterwards, when the goal is working out your personal tolerance. See the method page.
Barcode scanning. Monash deliberately has no scanner, because an ingredient list cannot show processing or portion effects. That is a fair point, and Clairop's answer is to be explicit about what it does not know: it breaks a product's ingredients into all six FODMAP subgroups (Varney 2017), cites the source for every value, and shows "no data" rather than guessing low.
Built for IBD too. Clairop calculates the Harvey-Bradshaw Index for Crohn's disease and PRO-2 for ulcerative colitis, logs blood, mucus, urgency and night-time movements, and produces a one-page GI visit report.
A common, sensible setup: use Monash during elimination to choose low FODMAP foods and serving sizes, and log in Clairop from the start so that by reintroduction it has enough data to show which foods and FODMAP groups you react to, and how long afterwards. The low FODMAP diet is meant to be a short, structured process, ideally with a dietitian, that ends with you eating as widely as you can, not a permanent restriction. See FODMAP reintroduction symptoms.
If you can only buy one app and you are just starting the low FODMAP diet, buy Monash: it is the reference and it is cheap. If you are past elimination, struggling to pin down delayed reactions, or living with Crohn's or colitis, Clairop does the job Monash's diary does not. Red-flag symptoms such as blood in the stool, unexplained weight loss or night-time symptoms always need a doctor promptly, whatever app you use.

Frequently asked questions
- Is Clairop a replacement for the Monash FODMAP app?
- Not exactly. Monash is a reference that tells you how much of a food is low FODMAP, measured in its own lab. Clairop is a tracker that finds which foods line up with your own symptoms, including delayed reactions. They answer different questions, and many people use Monash to plan meals and Clairop to learn their personal triggers.
- Is the Monash FODMAP app worth it?
- For most people starting the low FODMAP diet, yes. It is a one-time purchase, 7.99 US dollars on the US App Store, and its serving sizes come from laboratory testing by the team that developed the diet. Its limits are a diary that does no analysis, no barcode scanner, and some staple foods missing, according to recent store reviews.
- Why doesn't the Monash app have a barcode scanner?
- Monash has explained that an ingredient list cannot capture how processing and portion change a food's FODMAP content, so it prefers lab-tested and certified products. Clairop does scan barcodes, breaks the ingredient list into all six FODMAP subgroups with a cited source for each value, and shows unknown ingredients as no data rather than assuming low.
- What is the best FODMAP app?
- For lab-measured FODMAP content, the Monash University FODMAP Diet app is the standard. For finding which foods you personally react to, and when, Clairop is built for that job, testing every logged food against three delay windows up to three days. FODMAP Friendly is the other lab-testing programme with its own app.
- Is Clairop affiliated with Monash University?
- No. Clairop is not affiliated with or endorsed by Monash University and does not use Monash app data. Clairop's FODMAP values come from published food-composition research, including papers by Monash researchers, and each value in the app cites the paper it came from.
- Does the Monash app work for Crohn's disease or ulcerative colitis?
- The low FODMAP diet is studied mainly for IBS, and Monash says IBD symptoms need a doctor's assessment. Some people with IBD use it under a dietitian's guidance for IBS-like symptoms. Clairop calculates the Harvey-Bradshaw Index and PRO-2 score, which the Monash app does not.
- What is the best app for the low FODMAP diet?
- Use two: the Monash FODMAP app for lab-tested serving sizes during elimination, and a tracker such as Clairop to learn which foods and FODMAP groups you personally react to during reintroduction, including reactions up to three days later. If you can only buy one to start, buy Monash.
- What is the best free FODMAP app?
- The Monash app is a one-time purchase rather than free, at 7.99 US dollars on the US App Store. Fig is a free scanner and product database that its developer says is meant to be used alongside Monash. Clairop is free to download but needs a subscription to use.
- Does the Monash FODMAP app track symptoms?
- It has a diary for meals, symptoms and bowel habits, but it does not analyse them for you. Clairop compares meals with and without each food in three delay windows and reports which foods line up with worse symptoms, with false-trigger correction.
- Is the Monash app missing foods?
- Some. Recent Google Play reviews mention staples missing while branded products are well covered, and Monash says it keeps testing and adding foods. Where a food is not listed, Monash's lab data is unavailable, and any other app's estimate is just that, an estimate.
- Do I need a dietitian for the low FODMAP diet?
- It is strongly recommended. The low FODMAP diet is a short, structured process of elimination, reintroduction and personalisation, and a dietitian helps you do it without cutting more foods than you need. An app supports that process; it does not replace it.
Clairop is a general wellness app for people living with a diagnosed digestive condition. It does not replace professional medical care, diagnosis, or treatment. Always follow your healthcare provider's advice.
