Symptom & Function Diary

Most symptom trackers record how bad you felt. This one records what the symptom stopped you doing — the practical effect that is easy to forget by the time someone asks you to describe a pattern. Entries stay on this device: no account, no login, nothing sent anywhere.

1 — manageable10 — worst it gets
Tick anything that was harder than it should have been, then say what happened. This helps separate symptoms from practical effects.
This is a private record-keeping tool, not legal or medical advice, and it isn't a claim form. It won't decide anything on its own — an insurer or adjudicator weighs your own account alongside medical records and your doctors' opinions. Write only what is true, including the better days; a diary that shows the full range is more credible than one that only records the worst. If you're pursuing a claim, a disability attorney or advocate can tell you what your specific program expects. And because entries live in this browser, export a backup regularly — clearing your browser data will erase them.

Why severity alone can miss the practical effect

A severity score is useful context, but it is only one part of a useful record: a diary that records pain scores alone rarely moves a claim, because pain is invisible and unverifiable. What moves a claim is function — the gap between what the role or the day required and what you could actually do. "Fatigue, 7/10" is a feeling. "Fell asleep at the table at 2pm, couldn't finish the grocery run, left the cart and went home" is a limitation, and recording that practical effect can make your own history easier to review.

That is why this diary asks for severity first and then insists on the second half. The activity list is drawn from the everyday tasks that assessments actually ask about — dressing, washing, cooking, housework, shopping, driving, stairs, lifting, sitting and standing for a stretch, concentrating, sleeping, and getting through a work or school day. Ticking one opens a line to say what happened, in your own words.

Write it the day it happens

Claims are often decided months or years after the period being judged, and by then nobody remembers which week was the bad one. Contemporaneous notes — written at the time, not reconstructed later — carry more weight for exactly that reason. Short and frequent beats long and occasional: three lines several times a week builds a pattern, while one essay a month builds a story.

Record the good days too. It feels counterproductive when you're trying to show how limited you are, but a record with range in it reads as honest, and a record with no range in it invites the question of whether it was written to order. Variability is itself evidence in conditions that flare — showing that you can do a thing on Tuesday and not on Wednesday is often the whole point.

What happens to your entries

Everything is stored in this browser, on this device, using local storage. Nothing is uploaded, there's no account, and no one — including us — can read what you write. That also means the responsibility for keeping it is yours: use Export backup to save a copy somewhere safe, because clearing your browsing data will take the diary with it. Print full log gives you a clean dated document you can put in front of a doctor, an advocate, or a claim file.

Frequently asked questions

What should a symptom diary include for a disability claim?

Record the date, symptom, severity, duration, what activity was affected, any help you needed, what you tried, and any treatment side effects. These notes may help you describe patterns and functional effects, but requirements vary and this organizer does not determine eligibility or replace medical or legal advice.

How often should I write in a symptom diary?

Record entries close to the event when practical, including typical, better, and worse days. Consistent notes can make patterns easier to explain, but follow any instructions from your clinician, attorney, representative, insurer, or benefits agency.

Is this diary private?

Yes. Entries are saved in your own browser on this device and are never uploaded, and there is no account or login. Because the file lives on your device, you decide who ever sees it — but do keep a backup, since clearing your browser data will erase it.
