1.6 is for the moment you're not sure: a twinge, a bad morning, something new, and no idea whether to wait or call. Everything in this update is free. WHEN YOU'RE NOT SURE • Today and the Log tab have "Not sure what this is?". Three questions, one per screen. • First, the ten signs that mean call today, word for word as the app has always shown them. Tick any of them and the app shows the emergency number and takes you to the symptom log with that sign already ticked. • Then how long it has been going on. Three days or more means a call to your doctor today, even if it is mild. • Then what your own doctor told you to do, and, if you want one, a single reminder to check again. It is the only new notification, and it only comes if you ask for it. • The app never tells you what a symptom is. If you've checked three times in a week, it says the next step is a call to your doctor. • If you like, note how worried you are before and after. Only you see it, in Settings. MY DOCTOR'S PLAN • Write down what your own doctor told you to do at a first sign: when, what, who to call, and when to check again. In their words, not ours. • The app shows which parts are missing, and never fills them in for you. The plan prints word for word in your doctor's report. A CARD FOR THE EMERGENCY DEPARTMENT • One screen to show the staff: your flares and their dates, CT scans, hospital stays, your last antibiotics, allergies, current medicines and your doctor's number. Only what you recorded. • Share it as text or a PDF. Find it in My record, in "Not sure what this is?", and on Today during a flare. A SHORTER TODAY • Today is shorter: "I'm having a flare" is near the top, and one question at a time. Everything stays on your iPhone and, if you use iCloud, in your own iCloud.

1.5 puts what your own record says on one screen, and makes stages 1 and 2 free on every flare. MY DIVERTICULITIS • The Records tab is now "My record", and it opens on "My diverticulitis": your flares on one line, then what your own entries say. • Before this flare: the 14 days before each flare next to the month before that, in plain numbers. Fiber, water, discomfort days, twinges, antibiotics. It does not say what led to the flare; it shows you the two stretches side by side. • The five things: the five habits a large cohort study looked at, with your own fiber figure from what you log, and where you are on the other four, with the date you last looked. Once a month, Today asks if anything has changed. • Fiber by month: six months of your average daily fiber, from what you log. • Questions for your next appointment: up to seven, built from your own record, each with the fact behind it and where the guidance comes from. Share them as text. • In your record and Home from hospital from 1.4 live here too, with the doctor's report. WHAT'S FREE • Stages 1 and 2 are free on every flare, from now on. Nothing stands between you and the clear-liquid and low-fiber lists, and nothing asks you to pay while you are unwell. • Just home from hospital? Setup now asks, and the first-week-home checklist is free on your first flare. • Closing a flare is always free. When you are ready to move past stage 2 on a later flare, you can keep the app for the long run, or simply say you are eating normally and close the flare. • The urgent-symptom checklist, check-ins, logging, Looking back, food search and barcode scan, your flare history and every Learn article stay free. KEEP THE APP FOR THE LONG RUN • One purchase, no subscription. It covers My diverticulitis, the doctor's report, and stages 3 and 4 on every flare after your first. • The purchase screen now shows examples of what you get, labelled as examples, instead of a list. EASIER TO FIND • "Scan a barcode" now sits right under the food search, in words. • The ten signs that mean call your doctor today are in Learn, so you can read them before you need them. During a flare they are one tap from Today. • Settings shows how to add the Home Screen widget. • The tabs now match their screens: Today, Eat, Log, Learn, My record.

1.3 is about being understood. No new tracking, no new numbers — the same app, explaining itself as you go. TELL US WHAT YOU NEED • There is now an envelope beside the ? in the corner of every screen. It opens an email to us — ask for a feature, report a problem, or tell us about a food the search could not answer. • The draft carries the app's version and nothing about your health, and you read it before it sends. • If you have bought the app, that screen also has a button to rate it. Ratings are how other people with this diagnosis find it. URGENT SYMPTOMS • Two signs have been added to the urgent-symptom list: confusion or unusual drowsiness, and breathlessness with cold, clammy or blotchy skin. Both are things clinicians look for and the list did not ask about. • The emergency button now dials the number for wherever your phone is, and says which number that is before you tap it. It shows 911 here, 999 in the UK, 000 in Australia, and 112 anywhere it cannot be sure. • Recurrence figures are now sourced and stated as counts out of 100 people. The one unsourced percentage is gone. • The fever line leads with the unit your region reads — °F here, °C in most of the world. Both numbers are always there. • Learn now covers what published guidance says about painkillers — which one is usually named first, and which are advised against where possible, with the reason. SHOWN, NOT DESCRIBED • The three pages you see after setting up are now small demonstrations: a food being searched and logged, a day being rated in one tap, the four recovery stages moving forward and stepping back. • Short notes now appear on the control they explain, the first time you meet it — one at a time, never during an urgent-symptom warning, and gone once you tap "Got it". • Changed your mind? "Show the tips again" is in Settings. WORDS WE USE • A new page in Learn explains the words this app leans on: flare, twinge, stage, low-residue, trigger, base rate, red flag, CT-confirmed, complicated. Each one says what it means and why it matters to you. • The same explanations are one tap away from the screens that use them. IS THIS FLARE OVER? • A flare only ends when you say so, which meant one left open stayed open for ever — reading "Day 63 of recovery" at someone who recovered weeks ago. • If nothing has been recorded for a fortnight, the app now asks, offers the day of your last entry, and takes either answer. It still never closes a flare for you. FOOD • 688 foods, up from 656: peeled apple, raw carrots, baked potato, egg whites, bone broth, green tea, pumpkin soup, seaweed, ravioli, and dishes from bún chả to biryani, dosa, laksa and rendang. • Search now understands words in any order, so "carrots cooked" and "green tea" find what you meant. • Every food explains its answer. Type a medicine — ibuprofen, an antacid, a laxative — and the app says plainly that this is a question for your pharmacist rather than showing you an empty list. ALSO • Stages 2 and 4 now say, like the others, what would be worth a call to your doctor. • After you finish the last stage, the app takes you back to Today, where everything about life after a flare already lives. • "Create a report for my doctor" no longer sits there doing nothing before you have a flare on record — it says what it needs, and how to add one. • Clearer empty screens, a greeting that knows it is the afternoon, and "1 day" instead of "1 days".

1.2.1 fixes a crash some people hit opening the two-week check-in or Looking back, and a rare crash after deleting data. Everything below arrived in 1.2. New in 1.2 — about the weeks between flares, which is where most of the year is actually spent. HOW HAVE THINGS BEEN LATELY? • A short check every two weeks: six questions covering pain, bowel habits, worry, mood, what you have been avoiding, and how much it all affected your days. • It takes about a minute, and it builds the picture of the in-between weeks that is hardest to remember once you are sitting in the appointment. • Your answers appear as a plain month-by-month chart. No grades and no labels attached. • Free, with no purchase required. LOOKING BACK • One screen for "what did I log, and how is it moving?": a square for every day, coloured by how you rated it, with pain and flare days marked. Tap any day to open it in the diary. • Each flare in the period, in numbers: how long it lasted, the highest pain, the day pain fell to 2 or below, antibiotics, CT, the stage reached — beside your previous flare. During a flare, the same numbers so far, with what your previous flare had reached by the same day. • This period's counts beside the previous period's — days rated fine, days rated uncomfortable, check-ins, pain, water, fibre. Two numbers side by side; the app draws no conclusion from the difference. THE DAY AFTER • Some foods do not make themselves known until the next day. The daily diary now relates what you ate to how the following day went, and stays quiet until there is enough logged to be worth saying. BEFORE THE SURGERY CONVERSATION • What current guidance actually says about elective surgery, in plain words. • The numbers people ask for: how often another episode happens, how often long-term bowel changes are reported either way, and how often people say they regret the route they took. • Somewhere to write down what matters to you and take it to the appointment. Nothing you tick points towards surgery or away from it — it changes what your surgeon explains. • Also free. A LOOK AROUND, ONCE • New installs get a three-page introduction to the Eat, Log and Learn tabs. Skippable, and never shown a second time. THE DOCTOR'S REPORT • Now carries your two-week check-ins, the fortnight before your most recent flare, your personal trigger list, your colonoscopy status, and anything you wrote down for a surgical consultation. • Records only. Nothing is scored, ranked, or interpreted, and there is still no recommendation for or against any treatment.

New in 1.1 — shaped by what people wrote to us after launch. RECORDING A FLARE • Set the day your symptoms actually began, not the day you installed the app. • Start at the stage your doctor has already put you on — no need to say you feel better just to get there. A DAILY DIARY • One page for each day: what you ate, how each thing sat with you, and how the day went. • Rating a food is a single tap. Writing is always optional. • Foods you've eaten several times build up into "Things you've noticed". AFTER A FLARE • "What your last flare looked like" — your own record of the first days, to compare against. • Two new sourced reads: why lingering symptoms are common and usually not another episode starting, and why the fear that follows is worth raising with your doctor. • The app can hold your follow-up colonoscopy date and remind you a week before. ALSO • The food list has grown to 656 items, including a lot more of what people actually eat. • Clear-liquid guidance now says plainly what the guidelines say: it is for comfort, the evidence is limited, and moving on when you feel ready is fine.
