About this app

Find out what comes before your symptoms.

My Pattern Log is a private symptom tracker, food diary and medication reminder in one. Log a headache, a flare-up or a bad night, and the app looks back at what you ate, drank, took or did in the hours before — and whether that happens more often than usual. The coffee you drink every morning is not a trigger. The red wine that shows up before four of your five migraines might be.

LOG IN TWO TAPS
Your most common symptoms are one-tap chips — on the home screen and on a home-screen widget. Set how bad it is, pick "now" or "an hour ago", done. Meals, drinks, medicines and activities take a few seconds more.

MEDICATION REMINDERS
Add a medicine with its dose, times and days. Reminders arrive as notifications, and one tap marks it taken and logs it, so medicines sit in your history alongside everything else. Seven-day adherence at a glance.

PHOTOS ON ENTRIES
Attach a photo to any entry — a rash, a meal, an ingredients label. Photos are kept in the app's private storage on your phone and are never uploaded.

ADD CONTEXT
Sleep hours, mood, stress, water, exercise, bowel movements and cycle. Each one optional, each treated as a possible trigger.

PATTERNS, EXPLAINED PLAINLY
"Red wine came before Migraine 4 of 5 times, within 12 hours — 3.2x more often than usual." No percentages over 100. No correlations with the things you do every single day. Every pattern shows how many times it was seen, so you can judge it yourself.

SEE THE BIGGER PICTURE
Symptom-free, mild, moderate and severe days across 4, 8 or 12 weeks. Symptom logs per week. Average severity over time. Your most logged symptoms. A month heatmap in History, with search and filters.

A REPORT FOR YOUR APPOINTMENT
A PDF over the period you choose: a day split, a symptom table with average and worst severity, a weekly chart, what came before your symptoms, medicines logged, context averages, and an optional page for the questions you want to ask. Share it before you go in.

PRIVATE BY DESIGN
No account, no sign-up, no server. Your log lives on your phone. Back up to a file whenever you like, restore it on a new phone, and import a CSV export from another diary app.

DAILY REMINDER
One notification a day, at a time you choose — patterns only show up if you log ordinary days too. Off until you turn it on.

FREE, WITH PRO IF IT EARNS IT
Free: unlimited logging, history, patterns, charts, a 30-day doctor report, one medication with reminders, one photo per entry. Ads appear only on History and Insights — never while you are logging.
Pro: no ads, a report over 90 days, a year or everything, unlimited medications and photos, and Google Drive backup.

People use My Pattern Log to keep track of migraine, IBS and gut symptoms, endometriosis and period pain, fibromyalgia and fatigue, eczema, hives and allergies, joint pain, long COVID, and other symptoms that come and go from day to day.

My Pattern Log is for keeping track, not for diagnosis. Patterns are based only on what you log and do not prove cause. Talk to a healthcare professional before changing your diet, medication or routine.
