Tummily is an Irritable Bowel Syndrome (IBS) management app designed to make the low FODMAP diet easy.
Created by leading IBS expert Chelsea McCallum APD, Tummily combines personalised meal planning with an IBS symptom tracker to help people manage gut health and digestive symptoms like bloating, abdominal pain, diarrhoea and constipation caused by IBS, IBD or endometriosis.

EVIDENCE-BASED IBS SUPPORT
The low FODMAP diet is clinically proven to relieve IBS symptoms and improve digestive health. Yet many people feel overwhelmed, confused or unable to implement the diet effectively.
Tummily turns evidence-based nutrition into practical, personalised support. No guesswork. No overwhelm. No food anxiety.
Break free from overly restrictive eating and rediscover food as nourishment, variety and joy.

PERSONALISED LOW FODMAP MEAL PLANNER
Your personalised low FODMAP meal plan includes daily suggestions for breakfast, lunch, snacks and dinner, plus desserts and drinks.
Meals are tailored to your dietary preferences, food intolerances, allergies, dislikes and lifestyle needs.
Easily swap meals while staying within your plan, reduce impulsive food choices, and stay one step ahead of flare-ups. Track daily macros like protein and fibre to support your nutrition goals.

DIETITIAN-DESIGNED LOW FODMAP RECIPES
Enjoy delicious low FODMAP recipes designed by leading IBS dietitian and recipe developer Chelsea McCallum APD.
Every recipe is extensively tested so you can trust it works. Simple, nourishing and full of flavour, without unnecessary restriction.

SHOPPING LIST AND PLANNING TOOLS
Generate shopping lists directly from your meal plan to stay organised, reduce stress and stay consistent with your low FODMAP diet.

IBS SYMPTOM TRACKER AND FOOD DIARY
Track your IBS symptoms and digestive health your way.
Log only what matters to you, including bloating and gas, abdominal pain, bowel movements, diarrhoea or constipation, meals, exercise, mood, sleep, stress, medications and supplements.
Tummily is fully customisable, so your symptom diary reflects your unique IBS journey.

GUT HEALTH INSIGHTS AND PATTERN TRACKING
Your personalised insights graph helps you understand how symptoms change over time.
See how meals, habits, stress and treatments affect your gut health, identify patterns, and feel more in control of flare-ups.

PREPARE FOR MEDICAL APPOINTMENTS
It takes an average of 6 years to receive an IBS diagnosis. Tummily helps change that.
Turn your symptom logs and food diary into a clear, exportable PDF report to share with your doctor or dietitian, while staying in control of your data.

BUILT BY A LEADING IBS DIETITIAN
Tummily was founded by leading IBS dietitian Chelsea McCallum APD after years of supporting thousands through her digital clinic.
Too often, people with IBS are dismissed or left without clear tools to understand what is driving their symptoms.
Tummily was created to make personalised, evidence-based IBS support more accessible and empowering.

“Managing IBS can be life-changing, Tummily puts expert support in your pocket so you can spend less time guessing and more time living.”, says Chelsea McCullum APD.
