Logging symptoms
From the app’s English Help & Guide · Reference release 1.0.13
Log any symptom that stands out. The severity slider is calibrated: 3 = barely there, wouldn’t mention it; 5 = distracting but you can still get on with things; 7 = hard to ignore; 9 = had to stop and recover.
Log at the peak, not the start or end — peak severity is what you’ll want when comparing reactions later.
Mark today done
Marking a day done records completion only. It does not create a symptom-free entry. Log observations separately; leave missing information unknown. When recording a verdict, choose inconclusive if you cannot tell what happened.
