Log what you ate and how you felt, watch which foods keep turning up before a bad day, and bring a clear PDF report to your GI appointments. The diary is free; the report and longer trends need Plus, a one-time purchase.\n\nThe free diary is the whole app. Meals, symptoms, weight, sleep, energy, fluids, medications, your own safe-foods list, the per-food counts, flare mode and reminders cost nothing, with no trial and no logging cap. One optional in-app purchase, GastroLog Plus, adds the shareable PDF report and trend charts longer than a fortnight. It is a one-off, not a subscription, and is never needed to keep logging.\n\nIf you are working through a low FODMAP diet, GastroLog is where you write down what happened. You decide what is in and what is out; the app records how each meal went, so elimination and reintroduction rest on evidence rather than memory. The same applies to IBS, gastroparesis, reflux, chronic nausea and the months after gut surgery.\n\nA food diary that takes two taps\n\n- Repeat a meal in two taps. You eat the same safe things, and the app respects that.\n- Six usual meals stay pinned, so the food you eat most is always one tap away.\n- Say how much you actually managed, not just what was on the plate.\n- Missed a week? Nothing nags. Your diary simply continues.\n\nA symptom tracker with no typing\n\n- Nausea, vomiting, bloating, fullness and reflux, logged with big chips and a five-point severity scale.\n- One tap marks a rough patch, and the app quiets down until it passes. It asks for liquids, fluids and symptoms, and nothing else.\n\nLow FODMAP and IBS tracking\n\n- GastroLog does not hand you a FODMAP list. It records the one you are already working from, meal by meal, so a reintroduction that goes badly is written down while it is fresh.\n- Mark each food safe, trial or trigger as you learn it. That is your own low FODMAP result, worked out from your meals.\n- An IBS tracker that keeps bloating, fullness, reflux and the meals that came before them on one timeline.\n\nYour trigger food list, your call\n\n- Safe, trial and trigger lists that belong to you.\n- Once a food has some history, GastroLog shows the plain count — \"symptoms followed on 4 of 6 occasions\" — and you decide what moves where.\n- The app never labels a food for you and never hands you a diet plan. It counts what you logged.\n\nSee the shape of your weeks\n\n- The fortnight dashboard lines up symptoms, meals, weight, sleep, energy, fluids and medications on one screen.\n- Weight and symptom trends with the rough patches marked.\n- The fortnight view is free. A month, three months and the whole record need GastroLog Plus.\n\nThe report for your GI appointment (GastroLog Plus, a one-time purchase)\n\n- A clear PDF: symptom summary, weight trend, meal patterns, your food observations, medications, and the questions you want to ask.\n- Built from your diary in seconds, shared straight from your phone.\n- Walk in with your story on paper, instead of trying to remember six weeks of meals in a ten-minute slot.\n- Page one previews free, so you can see it before buying.\n\nWho uses a food symptom diary\n\nPeople managing IBS, the low FODMAP elimination and reintroduction phases, gastroparesis, diabetic gastroparesis, functional dyspepsia, reflux, chronic nausea, cyclic vomiting and post-surgical slow emptying. Anyone told to \"keep a food diary and see what sets it off\" and handed no tool to do it with. If you are tracking meals against symptoms over months rather than counting calories for a week, this is built for you.\n\nPrivate by design\n\n- Everything you log stays on your phone. There is no account and there are no ads.\n- Anonymous usage counts show us which features get used, never what you logged or who you are.\n- Export or delete all of your data whenever you want.\n\nGastroLog is a diary, not a medical device. It counts and shows what you logged. You and your care team decide what it means.","facts":{"developer_id":6776025575,"developer_url":null,"first_released":"2026-06-16T07:00:00Z","support_url":"https://digitalbrain.co.nz/","privacy_url":"https://digitalbrain.co.nz/privacy/","website_url":null,"app_version":"1.10.0","release_notes":"Name your meals, like Porridge or Steak and eggs.
