Natural-language symptom tracker

Track symptoms without another complicated form.

Write what happened in the words you already have. Health Diary helps preserve severity, timing, duration, body area, triggers, and relievers—then makes the pattern easier to review.

Natural-language symptom entry in Health Diary on iPhone

Capture the real story

Start with a sentence, not a medical questionnaire.

When you do not feel well, the last thing you need is a long form. Describe the symptom, context, or change naturally. Health Diary helps turn that note into an editable, consistent record.

What it felt like

Keep the symptom, severity, body region, and duration together.

When it happened

Record dates and timing so repeated episodes do not blur together.

What may have affected it

Save possible triggers, relievers, activities, meals, or weather context.

What else was going on

Add mood, energy, sleep, notes, and optional Apple Health context.

Patterns over time

Memory fades. A timeline keeps the useful details.

Review symptom frequency, severity distribution, common triggers, body areas, and records across the date range you choose. Filter the timeline when you want to focus on one symptom or period.

Appointment preparation

Walk in with a clearer account of what changed.

Health Diary can help you review when symptoms appeared, how often they returned, what felt different, and which details you want to mention. The goal is better recall and organization—not a diagnosis.

  • Choose the date range that matches your concern
  • Filter records by symptom and structured details
  • Review trends before the conversation
  • Keep the original notes behind every summary
Know when to seek help.

If you have severe, sudden, or emergency symptoms, contact local emergency services or a qualified healthcare professional instead of relying on an app.
