About this tool
Log symptoms, monitor severity, and detect health patterns
Symptom Diary is a symptom diary that records each episode with a 0–10 severity rating alongside the date, time, duration, suspected trigger, medication taken, mood, energy and sleep quality, then charts those entries so patterns become visible. Severity is banded as mild at 3 or below, moderate from 4 to 7 and severe at 8 or above, and the dashboard plots your last 10 entries as a severity trend, breaks entries down by category and trigger, and overlays sleep quality against severity. Everything can be exported as CSV or as a PDF report with the charts and a dated table, which is what you hand to a clinician.
Open Symptom Diary on AltFTool — it loads instantly in your browser.
Fill "Symptom Name", pick a "Category", drag "Severity Level" between 1 and 10, then add "Trigger", "Duration", "Medication" and the Mood, Energy and Sleep scores.
Press "Add Log Entry" — the dashboard appears and charts your most recent 10 entries as a severity trend with sleep quality overlaid against severity.
Under "Export Health Reports", "Save PDF" and "Save CSV" download symptom_diary_<date>.pdf and symptom_diary_<date>.csv, and "Print Log" prints the timeline.
Every entry carries a trigger from a 15-option list plus mood, energy and sleep-quality scores, which is what makes the later pattern analysis possible.
The dashboard overlays sleep quality with symptom severity across your recent entries, and flags the average severity of episodes that followed a sleep score of 4 or below.
The export renders the charts as an image followed by a dated table of symptom, category, severity, trigger and medication — appointment-ready without transcribing anything.
It is a 0–10 slider that you set yourself, and the tool groups the results into three bands: 1–3 mild, 4–7 moderate, and 8–10 severe. Consistency matters more than precision — pick a personal anchor for what a 5 feels like and rate against it every time, so the trend line means something.
The insight panel stays quiet until you have at least three logs, and the trend charts show your most recent 10 entries. In practice, a few weeks of consistent logging is what turns a list of bad days into a visible relationship between a trigger, your sleep and how severe the episode was.
No. Entries are stored in this browser's localStorage under a single key and never leave the device, which also means clearing site data or switching browsers deletes them — export the CSV periodically if the history matters to you.
No, and it does not try to. It records what you report and summarises it; it makes no diagnosis and suggests no treatment. Correlations it surfaces — such as worse symptoms after poor sleep — are patterns in your own entries, not medical conclusions, and any recurring, worsening or sudden severe symptom needs a doctor.
