How to use this symptom and mood tracker online

A short daily check-in is often easier to keep up than a detailed diary. Record the information that matters to you, then use the calendar heatmap as a memory aid when reflecting on routines, triggers or questions you may want to discuss with a qualified healthcare professional.

1

Choose how the day felt

Select a mood and rate only the symptoms you noticed. Zero means that symptom was not present.

2

Add useful context

Optionally note sleep, energy, possible triggers, helpful activities or anything unusual about the day.

3

Review your heatmap

Look across the month for clusters or changes. Click any date to review and update its journal entry.

Important: This journal is for personal tracking and reflection, not medical advice, diagnosis or treatment. Seek professional care for health concerns, and urgent help for severe or sudden symptoms.
