Symptom log
People often ask “why am I getting hives, or hayfever, or reacting to something?” — and the honest answer is that a questionnaire can’t diagnose that. What it can do is organise your symptoms, timing and suspected triggers into a clearer pattern you can bring to a clinician, and — where it’s safe — help you run a structured single-food trial. 100% Private. Everything stays on your device.
What this tool is
A structured log of symptoms, timing and possible triggers. It produces a pattern label— for example, a rhinitis-like pattern, a recurring-hives pattern, or a delayed-intolerance pattern — and tells you what is and isn’t worth doing yourself before seeing a clinician.
What this tool is not
Not a diagnosis. Not a substitute for clinician-led allergy assessment. Food allergy — the kind that causes immediate hives, swelling or breathing difficulty — is a clinical diagnosis (history plus targeted testing or supervised challenge). If your history involves any severe reactions, please work with a clinician rather than a self-tool.
Why a pattern, not a diagnosis
Food allergy testing is clinician-led for a reason: home questionnaires can’t reliably tell allergy from intolerance, and broad self-administered allergy panels have a high false-positive rate that can lead to unnecessary food restriction. We describe patterns instead.
When a single-food trial helps
For delayed, non-systemic, non-dangerous symptoms (GI bloating, post-meal fatigue, headaches with food), a structured 2–3 week single-food elimination and short reintroduction is a reasonable thing to try with clinician awareness. The worksheet is offered only for those patterns, and only when it’s safe.

Companion tool
Pair this with the symptom journal to log severity over weeks. The picture you can show a clinician after a few weeks of structured logging is far better than memory alone.
