Food & symptoms · Food Allergy
A reaction log for an allergy you already have a diagnosis for
This page is for managing an allergy that has already been diagnosed — not for working out whether you have one. That's a clinical question with actual tests behind it, and guessing at it with an app is both unreliable and, with the wrong food, dangerous. What a log is genuinely good for is the part clinics always ask about and nobody has kept: where the accidental exposures came from, how fast reactions started, and whether anything is changing.
For people managing a diagnosed food allergy, and parents managing a child's.
Why this is hard to keep track of
- Accidental exposures are the events that matter and they happen in the middle of chaos
- Whether this reaction was worse than the last one is unanswerable from memory
- Recipe and label changes cause repeat incidents with the same trusted product
- The clinic asks for a history that nobody has been keeping
Worth recording
- What was eaten and where it actually came from
- Symptoms, how fast they started, and how severe
- What treatment was given and whether it was adrenaline
- The source — a label, cross-contact, a restaurant, a school
Cadence
Logged after the event, once everyone is safe
In practice
Say it once, in whatever words you have
The moments most worth recording are the ones where filling in a form is the least realistic thing in the world. A sentence, typed or dictated afterwards, is a much lower bar — and it carries the context a checkbox would have lost.

Every figure here was counted from entries you made. The model picked which tools to call — it doesn't interpret, diagnose, or decide what anything means about anyone.
And then ask
The question the log can answer
Months of entries hold real answers to the questions you've been guessing at, and reading them properly has always meant a spreadsheet and a free evening — which is not a thing anyone in this situation has.
Ask in plain language. The answers come back with the numbers behind them, including when those numbers are too thin to mean anything yet — which is the more useful answer more often than people expect.
Called 3 tools
get_history(topic: "food-allergy", window: "6m")find_pattern(group_by: "antecedent")compare_periods(metric: "events")
Counts and averages over your own entries, nothing more. Where the data is confounded or too thin, the answer says so instead of rounding it into a conclusion.
The reason most people start
Something to actually bring to the appointment
You get fifteen minutes, once, after waiting months for it. The questions are specific and the honest answers are all some version of "I don't know, it's hard to say".
What this gives you: An exposure and reaction history with severity and onset times — exactly what an allergy review asks for and almost nobody arrives with.
- Export the date range you were asked about, as a file you can print
- Counts and timings rather than an impression of the worst week
- Your own notes kept alongside the numbers, in your words
- Nothing shared anywhere unless you choose to share it
What it won't do
- Diagnose anything, or suggest that it could
- Score a person, or rank them against anyone else
- Set a target for fewer events, or a streak of good days
- Recommend a treatment, a therapy, a diet or a medication change
- Share your record with a school, a clinician or anyone else on its own
It's a notebook that can do arithmetic and answer questions about itself. Deciding what any of it means is a job for you and the people advising you.
