Log Flares With Times and Triggers Until the Pattern Is Undeniable — Free

'It happens most weeks' is not usable, and it is not true either: flares cluster. This card takes dated entries with times and suspected triggers, counts how many fall inside the window you set, and compares that against the threshold you decided in advance — the point at which you said you would go back to the specialist in writing. Quiet weeks stay in the log, because the gaps are part of the pattern.

The proof surface

Free path: the card computes locally in the browser with no key and no account. Where an AI step helps, any free chat assistant works — Google AI Studio's free tier and Groq's free tier were both no-card and rate-limited when this page was reviewed on 2026-09-13 (limits change; check before you rely on them).

Why the flat version breaks

A symptom diary in a notebook cannot tell you that four of the last six flares followed a night shift, because it never counts anything and never holds a threshold. Dated entries with a window and a number attached turn an impression into a pattern you can quote, and a threshold you set while calm is the thing that stops a bad month being normalised.

How to use the flare diary index card in four passes

Write the entry in the moment, with a time

Times are what turn a diary into evidence: 06:20 after a night shift means something that 'a bad day' does not. Add the line the same morning rather than reconstructing a month later.

Record the suspected trigger even when you are unsure

Mark it as a suspicion. Three flares after night shifts is a pattern a consultant can test; three flares with no context is three anecdotes.

Set the threshold before you need it

Pick the count at which you said you would write to the specialist — four in thirty days is the starter figure. Setting it while calm is the whole point; renegotiating it during a bad week is how a year disappears.

Keep the quiet weeks in the log

Do not prune the entries that look unremarkable. The span of the log and the gaps between flares are part of what a specialist reads, and a log with only bad days in it invites the wrong conclusion.

SAMPLE DATA, NOT A VERIFIED CLAIM: Crohn's, stable on azathioprine · 22 Jul – 18 Sep 2026 · seven entries · four inside the 30-day window · three of them after a night shift · threshold 4. Replace these values with your own source before you rely on anything.

What breaks first

Recording symptoms instead of events

'Felt awful all week' is one entry with no time and no trigger. Split it into the days it happened; the card counts entries, and a week-long smear counts as one.

Moving the threshold when it is nearly crossed

That is the failure mode this card exists to prevent. If the threshold is genuinely wrong, change it in the log with a dated note, not silently.

Reading a trigger column as a cause

Two flares after red wine is a hypothesis worth testing, not a diagnosis. The card never verifies anything; it counts what you wrote and hands it to someone who can.

Boundary: This counts the entries you type; it is not a diagnosis, it cannot verify a trigger, and it must not be used to change medication or treatment. Take the log to your clinician and let them interpret it — and seek urgent care rather than logging if symptoms are severe or new.
