Is it possible to add a comment or note to the Health app? I could see this ability as a useful way to interpret or supplement the data.

For example, if I'm sick for a few days, it could explain a change in my diet or weight. ("Today was Day 3 of flu symptoms, but I'm feeling better than yesterday.") Or, if I'm on a medication, I might want to make notes of any observations. ("I forgot to take my X pill last night; today, I have a headache.")

Adding notes in Health.app

No, as of iOS 10.3.x you can't add comments to Health.app and its database.

Alternative (3rd party apps)

If you want to enter any notes or observations you need to rely on a third party app to do so.

Ideally, this app should be able to export your notes in a non-proprietary format like XML. Not all apps (e.g. Pillow) with a notes feature allow you to do that. (Thanks @Mark)

Alternative (use unused fields)

You may use unused Health.app fields to store your observations. Below are special data types that exceed the usual 'one value + one time stamp' values.

With graphs

  • UV Index (one number, start time, end time)
  • Sleep Analysis (three values, start time, end time)
  • Blood Pressure (two numbers)

Without graphs

  • Carvical Mucus Quality (five values)
  • Menstruation (four values + one boolean (yes/no))
  • Ovulation Test Result (three values)
  • Sexual Activity (three values)

You could totally add 'UV Index' (value + duration) for headaches and 'Vitamin B12' for forgotten medications. Add them to Health.app's Today view using the 'Add to favorites' toggle and you're done.

  • And the third party apps don't always export that - e.g. Pillow

  • Thanks, @oa- . That's not the answer I wanted, but so be it. This issue has led me to ask a related question: apple.stackexchange.com/q/284576/72448

It appears that as of iOS 16.3.1, you still can’t add notes in the Health app.
