DaylogBloating, stomach aches, headaches — and no idea which food did it?
Daylog is a free food, symptom and sleep journal. Log a meal or a bad hour in a few seconds, and it lines them up over time to show which foods keep turning up before you feel bad. Made for anyone told to "keep a food diary" — for themselves or for their kid.

Entries take seconds
Say it out loud or type one sentence — "turkey sandwich at 12:30, mild stomach ache at 2" — and each part is filed with the real time it happened. Meals, symptoms, Bristol scale, sleep, medication, where you were.
Useful from day one
Your timeline is readable straight away — a clear dated record you can scroll or hand to a doctor. Pattern checks need roughly two to three weeks of days logged before the numbers mean much.
See what lines up
Daylog checks each food exactly as you typed it, then groups like dairy or gluten, across four time windows after eating — and shows the days behind every finding instead of a vague score.

Bring it to your doctor
Print, copy or save a clear report of your month. Daylog never diagnoses — it shows co-occurrence, so you and a professional can decide what's worth testing.
