Proven IBS symptom relief
The low FODMAP diet is clinically proven to provide relief from:
Bloating
Abdominal pain
Gas
Diarrhoea
Constipation
Created by leading IBS expert, Chelsea McCallum, APD
“The low FODMAP diet is one of the most effective treatments to manage the digestive symptoms associated with IBS and endometriosis, but time and time again I’d see clients overwhelmed, confused and unable to implement this diet effectively.
They felt anxious, scared of food, and stuck in overly restrictive diets that lack nourishment, variety and joy. For many, the diet felt so exhausting that living with crippling symptoms seems easier than trying to follow it. That’s why I created Tummily.”

Our origin story
Tummily began with a shared frustration and a chance meeting.
Dietitian Chelsea McCallum was growing increasingly disheartened by what she saw in clinic. Despite the low FODMAP diet being highly effective for managing the digestive symptoms associated with IBS, IBD, SIBO and endometriosis, her clients felt overwhelmed by complex food lists, portion confusion, and symptom tracking that felt more like a chore than support.
Meanwhile, app designer Alison Williams felt frustrated with the IBS apps available. Managing symptoms meant scrolling endless ingredient lists and symptom tracking apps that were anything but intuitive.
When Chelsea and Alison met at the Free From Allergy Show, they immediately connected with a shared vision. Both believed people with IBS deserved better than restriction, confusion, and anxiety around food.
Together, they created Tummily. An app designed to make managing IBS clearer, calmer, and more personalised, without sacrificing nourishment, variety, or joy.
