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.

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

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.

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.

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.

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.

Large type, high contrast, one main action per screen. Your records stay on your iPhone, and the App Store label reads Data Not Collected.
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.
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.
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.
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.
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.
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.
For an uncomplicated flare treated at home, pain usually starts to ease within two to three days and most people are largely settled within one to two weeks, with tiredness lagging several weeks behind. A flare that has not improved after two or three days, or that is getting worse, is a reason to contact your doctor rather than wait.
Diverticulosis is the presence of small pouches in the colon wall, which is common with age and usually causes no symptoms. Diverticulitis is when one becomes inflamed or infected. Most people with diverticulosis never have a flare, though published estimates of how many do vary widely, from an older figure of up to a quarter down to around one in twenty-five in more recent long-term work.
Seek urgent care for severe or worsening abdominal pain, a fever, rectal bleeding, persistent vomiting, or if you cannot keep liquids down. These can indicate complications that need treatment rather than rest and a soft diet. If you are unsure, that uncertainty is itself a reason to call.
Plain-English answers to the four things people most often want to know about diverticulitis. General wellness information, never a substitute for the clinician treating you.
Where diverticulitis usually hurts, why it can be on the right, and the other conditions that cause pain in the same place.
Read the guide ->Clear liquids, then low residue, then fibre back. What each stage usually allows, and why the advice inverts everything you know about healthy eating.
Read the guide ->The shape most uncomplicated flares follow, the parts that lag behind the pain, and the point at which slow recovery stops being normal and becomes a phone call.
Read the guide ->Where the lifelong ban came from, what the research actually measured when it finally looked, and why these foods still come out during a flare for a different reason.
Read the guide ->One is a finding on a scan, the other is an episode. The difference decides which diet advice applies to you, and getting it wrong is the most common mistake here.
