For people in the UK living with IBS
Find your IBS triggers. Win back your food.
MellowGut is a photo poo diary and a 12-week programme built on NICE guidance for IBS. Log in seconds, see your patterns, and test foods one at a time until you know what really sets you off.
What you could win back
How it works
Most people with IBS are told to “watch what they eat”. MellowGut turns that guesswork into a plan.
- 1
Log in seconds
Snap a photo for an instant Bristol type, or tap the chart. The photo is deleted straight after. Add how you feel and what you ate, in under a minute a day.

See your pattern
After 7 days, your Pattern Report shows what lines up with your good days and your flare-ups, in plain English.

Test, don’t guess
A 12-week programme built on NICE guidance: foundations, a short low-FODMAP reset, then Trigger Detective food tests that bring foods back one at a time.
Safe and private by design
Your GP comes first
A safety check at the start. Warning signs like bleeding or weight loss pause the food programme until a GP has checked you.
Kind to your relationship with food
If food already feels stressful, we start you on the Mind track with daily gut-directed hypnotherapy audio instead of cutting foods out.
Photos are never stored
Analysed, then deleted. We keep only the result, like “Type 4”. Never in the cloud, never in your camera roll.
Your data stays yours
Health data is stored in the UK, never sold, never used for ads. Download or delete everything from the app, any time.

Questions
Is MellowGut a medical app?
No. MellowGut helps you manage IBS symptoms and understand your own patterns. It doesn’t diagnose or treat any condition. If you haven’t been diagnosed with IBS, or your symptoms change, please see your GP.
When does it launch?
We’re aiming for spring 2027, on iPhone first, with Android after. Join the waitlist and we’ll email you before launch.
How much will it cost?
The 7-day diary and Pattern Report are free. The full programme is planned at £79.99 a year or £14.99 a month. The first 500 founding members can get lifetime access for £99.
What happens to my photos?
They’re analysed and deleted straight away. We only keep the result, like “Type 4”. You can always use the tap chart instead of a photo.
Where is my data stored?
Your health data is stored in London. It’s never sold or used for advertising, and you can download or delete all of it from the app.
