Diverticulitis diet and flare app for iPhone. What can I eat
right now?

A diverticulitis flare is frightening, and the scariest question is the simplest one. Diverticulitis Coach walks you through recovery one day at a time, so you always know what is safe to eat today and what the next stage looks like.

Why this app exists

Fifty thousand people were building their own diary.

The largest diverticulitis community online, around fifty thousand people, resorted to building their own web diary because no decent app existed. Searching the App Store for diverticulitis returns mostly noise. Meanwhile the advice people are handed is a photocopied sheet that says clear liquids, then low residue, with no guidance on what that means for the sandwich in front of you.

🍽️

The same food changes answer

Whole grains are the goal between flares and the wrong choice during one. A single food list cannot serve both, so most lists quietly mislead you half the time.

📋

Nobody tells you when to move on

The sheet says advance as tolerated. That leaves you deciding alone whether day four of clear liquids is progress or a problem.

🥜

Decades of wrong advice about nuts

Many people were told to avoid nuts, seeds and corn for life. Large studies do not support that, and nobody ever went back to tell them.

How it works

One stage at a time, at your pace.

Flare Mode

A plan that waits for you

A guided route through clear liquids, low-residue foods and gradually adding fiber back, with the exact allowed and avoid lists for each stage.

You decide when to move on, never the app. It shows what most people do and suggests talking to your clinician, then waits until you say you are feeling better.

Can I eat this?

568 foods, answered for today's stage

Search any food and get an answer for the stage you are in right now. The same food can be a yes today and a no next week, and the app explains why instead of leaving you to guess.

This is the part a printed list cannot do, and the reason people were keeping spreadsheets.

Honest content

The truth about nuts, seeds and corn

If you were told to avoid them for life, large studies do not support that advice. The app explains what the evidence actually says, and why they are only left out during one temporary stage.

We put this in writing because getting it wrong in either direction damages trust, and this community has been misinformed for decades.

Every day, not just crises

Flare-free days, counted

A ten-second daily check-in, water and fiber tracking, and a running count of your flare-free days. Between flares the goal flips: fiber becomes the thing to build back up, and the app flips its scoring with you.

For your doctor

A clean record, presented neutrally

Dates, durations, antibiotics, whether a flare was CT-confirmed, all in a plain PDF for your GP or surgeon. It is presented without a recommendation either way, because a surgical decision is not an app's to steer.

FAQ

Questions people ask mid-flare.

What can I eat during a diverticulitis flare? +

Most guidance moves through stages: clear liquids first, then low-residue foods such as eggs, white rice, tender chicken and ripe banana, then gradually adding fiber back. The app gives the exact list for the stage you are in today and explains why a food that is fine now may not be later. Follow the plan your own doctor gave you.

Do I really have to avoid nuts, seeds and corn forever? +

Large studies do not support lifelong avoidance, and this advice has persisted long after the evidence moved. The app explains what the research actually found and why these foods are only left out during one temporary stage. Your own clinician's advice comes first.

Can the app tell me whether I am having a flare? +

No, and it will never try. It cannot diagnose anything. If you have severe pain, a fever, bleeding, or cannot keep liquids down, contact your doctor or emergency services now. The app shows that guidance rather than a food list when you report those symptoms.

When should I move to the next stage? +

That is your decision with your clinician, not the app's. It shows what most people do and how many days you have been in the current stage, then waits for you to say you are feeling better. It never advances you automatically.

Is it a subscription? +

Your first flare is completely free with every stage unlocked. After that, a single $12.99 purchase unlocks future flares permanently. We chose a one-time purchase rather than a subscription because this audience has had enough of recurring charges.

Is my information private? +

Yes. There is no account, your records stay on your iPhone, and there are no ads or third-party trackers. The App Store privacy label reads Data Not Collected.
