The IBS Reality

The part nobody talks about when they say "just eat low-FODMAP."

IBS isn't just a stomach issue. It's the dinner you couldn't enjoy. The morning you spent on the bathroom floor. The doctor who told you it was stress. The years you've already lost to guessing.

01

You plan your life around bathrooms.

Where you sit at restaurants. How far you'll travel. Whether you can say yes to that date, that trip, that meeting. Every food is a gamble you can't afford to lose.

02

Doctors keep telling you it's stress.

You leave appointments with a vague FODMAP printout and a "let's see how it goes." Nobody's giving you a real system. Just patience you've already run out of.

03

You're exhausted from being exhausted.

Brain fog after every meal. Cancelled plans you can't explain. Trial-and-error elimination diets that fall apart by week 2. You don't even remember what feeling good feels like.

Lifelong Freedom

You know exactly what you can and can't eat. The app stays your daily companion: scan, log, eat with confidence.

What's on the other side

By Day 21, your life starts looking like yours again.

Not a miracle. Just clarity. When you finally know what your body can and can't handle, everything changes.

Day 7

"I forgot what it feels like to wake up without bracing."

Your gut score climbs. Mornings stop being a coin flip. You're getting honest sleep again, and the brain fog you blamed on age starts lifting.

Day 14

"I went out to dinner. And I actually ate."

You scan the menu, you order, you stop apologizing. The 3 magic questions to ask the waiter. The 20 restaurant meals that are reliably safe. Eating with people stops feeling like a tightrope.

Day 21

"For the first time in years, I trust my body."

You finish elimination with a clear baseline. You know your safe foods. You're ready to test, with confidence, which triggers you can handle, in what doses. The guessing is over.

Food Scanner

Know before
you eat.

Scan any meal or ingredient to see if it may trigger your IBS.

The afternoon burger introduced fructans through the bun and fried onions in the patty. That's likely behind your evening cramping.

6 years with IBS

I was so tired of trying to figure this out alone. By Day 7 my gut score was climbing. By Day 14 I had my first dinner with friends without bracing for the morning after.

4 years with IBS

It was affecting my marriage. My partner used to dread eating out with me. We had dinner with their parents last week and I forgot to be anxious. That's the win.

I had a destination wedding 5 weeks out. I started this program desperate. It got me through the trip, the dinner, the speeches, without a single emergency.

My GI just said "try low-FODMAP" and sent me home. That was useless. This program walked me through it day by day. By Day 21 I knew exactly which foods were triggering me.

FAQ

Questions we get all the time.

What is the low-FODMAP diet exactly?
It's a 3-phase approach developed at Monash University to identify food triggers in IBS. You eliminate fermentable carbohydrates (FODMAPs) for about 3 weeks, then systematically reintroduce them one group at a time to discover which ones YOU react to. Studies show about 76% of IBS sufferers see meaningful symptom improvement.
Why 21 days for elimination? Some protocols are longer.
Monash recommends 2 to 6 weeks for elimination. 21 days is the sweet spot: long enough to see clear symptom changes, short enough to stay motivated. If you need more, you can extend in-app. Most users see results within 21 days.
Do I need a doctor's referral?
No. GutAI is an educational and tracking tool, not a medical service. However, if you suspect IBS or experience severe symptoms (blood in stool, severe weight loss, etc.), see a doctor first to rule out other conditions. Use our Doctor Report feature to share your data with your GI specialist.
What happens after the 49 days?
You keep your subscription as your daily gut companion: scan foods, log meals, see your personal trigger map. The whole point is lifelong freedom, knowing what works for YOUR gut. The app gets smarter the more you use it.
What if it doesn't work for me?
IBS is highly individual. While 76% of users see improvement on low-FODMAP, not everyone does. We offer a 3-day free trial so you can test before paying. After that, you can cancel anytime in your App Store settings. No questions asked.
Is this just for IBS, or other gut issues too?
The program is specifically designed for IBS-type symptoms (bloating, gas, irregular bowels, cramping). It can also help people with general FODMAP sensitivity. It's not designed for IBD (Crohn's, ulcerative colitis), SIBO, celiac disease, or food allergies. For those, see a specialist.
Will I have to give up bread, garlic, and dairy forever?
No. That's the whole point of reintroduction. After Day 21, you systematically test which foods YOUR body tolerates. Many people find they can still enjoy garlic-infused oil, lactose-free dairy, sourdough bread, and more. The goal isn't restriction, it's clarity.
Can I do this if I'm vegetarian or vegan?
Absolutely. The recipe library includes vegan and vegetarian options for every category. The AI coach also adapts to your dietary preferences set during onboarding.

You've already waited long enough.

Take the 2-min quiz. We'll show you what your trigger profile likely looks like, and whether this program is your way out. Your first 3 days are free.
