About

Gutline is a private diary for people managing IBS and following a low-FODMAP diet. It takes about ten seconds a day, and it turns your record into a report you can hand to a doctor. WHAT YOU LOG - Overall severity, 0 to 10 - The Bristol stool scale, with an explicit "not recorded" - Eight symptoms (bloating, pain, gas, urgency, fatigue, nausea, constipation, diarrhea), each mild, moderate or severe, plus symptoms of your own - Medication taken, urgency and blood, if they apply - The triggers you choose, plus your own typed tags - Meals, drinks and habits, with a reaction check afterwards: none, mild, moderate or strong - Your medication and therapy plan, ticked off each day - A photo on any entry WHAT YOU GET BACK - Today at a glance: severity, stool, symptoms, medication and food in one view - "Same as last" for a steady day: one tap copies your previous entry - History grouped by day and searchable - Patterns: severity over time, stool types, symptom averages and the tags you use most - Highlights: plain sentences of fact from your own entries - What tends to travel with your worse days, from your own record - Your days with and without each item on your plan, side by side - What you recorded after each meal, drink or habit - A day by day view of severity and stool - A clear PDF report for your next appointment, and a CSV export PRIVATE BY DESIGN - No account, no sign in, no server - Your diary stays on your iPhone and leaves only when you export it - Face ID lock, if you want it - No ads and no tracking GUTLINE PRO Gutline is a subscription. Gutline Pro includes unlimited entries, 14 and 30 day patterns, the tag comparison, the PDF report and the CSV export, the photo log, the Face ID lock and a daily reminder. Any free trial on offer is shown before you subscribe. If you stop subscribing, everything you logged stays readable on your iPhone. Gutline records what you enter. It is not a medical device and it does not give medical advice. Talk to your clinician about your symptoms. Gutline Pro is an auto-renewable subscription.
