Less stress over labels. Clearer choices in seconds.

No more spending ages decoding ingredient lists or always reaching for the same familiar products.

  1. Scan the barcode

    Point your camera at any product. Belly Buddy reads the full ingredient list instantly.

  2. Get a clear verdict

    Green, amber or red, with the ingredients that influence the rating and low FODMAP portion guidance.

  3. Decide more easily

    Get the information you need to make your choice, right there in the aisle.

Not just a scanner. A 12 week path.

Most people see clear improvement in 4 to 12 weeks. Belly Buddy walks you through both phases.

  1. 1

    Elimination, weeks 1 to 6. High FODMAP ingredients out. Symptoms settle.

  2. 2

    Reintroduction, weeks 6 to 12. Foods back, one group at a time.

  3. 3

    You know your triggers. The widest diet your belly can handle.

Typical timings based on Monash University's public research. Not a medical treatment, and results vary.

Questions? We've got answers.

What are FODMAPs, exactly?
FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols. In plain English, they are types of carbohydrate that the small intestine absorbs poorly. You will find them in everyday food like garlic, onion, apples, wheat, beans and dairy. If you have IBS, they can ferment in your gut and leave you with bloating, gas, cramps and general discomfort. The low FODMAP diet, developed by Monash University, is the most scientifically backed way to manage IBS symptoms. Read the article
How does Belly Buddy actually work?
Point your phone camera at any product barcode and Belly Buddy reads the ingredient list against the FODMAP database straight away. You get a clear traffic light rating (green, amber or red) and you can see exactly which ingredients are the problem. If a product is not a good fit, we suggest similar low FODMAP options. No more squinting at tiny labels or googling every ingredient.
Is Belly Buddy a replacement for a doctor or dietitian?
Not at all. Belly Buddy is a supportive tool that makes following your prescribed low FODMAP diet easier day to day. It does not replace professional medical advice, a diagnosis, or the personal guidance your healthcare team gives you. Always talk to your doctor or dietitian about your IBS plan. Think of Belly Buddy as the helpful companion between appointments.
Who is this app for?
Belly Buddy is built for people who have been diagnosed with IBS by a healthcare professional and are following, or thinking about following, a low FODMAP diet. It also helps if you have finished the elimination and reintroduction phases and want support keeping things steady. If you have not been diagnosed, please see a healthcare provider first, because digestive trouble can have many different causes.
How accurate is the FODMAP information?
Our FODMAP data comes from Monash University's public research (they created the low FODMAP diet) and other peer reviewed scientific sources. We update the database as new research lands. That said, tolerance varies from person to person, so treat Belly Buddy as a starting point and pay attention to how your own body responds. When in doubt, ask your dietitian.
Where can I get Belly Buddy?
Belly Buddy is on the App Store now for iPhone and iPad. An Android version is in the works, so join the Android waitlist on this page and we will let you know the moment it is ready.
