Start now, add detail when ready
Begin or end an episode in seconds, then record intensity, locations, symptoms, observed factors, actions, and optional notes.
Facts, never medical conclusions
Review a searchable history and transparent 30- or 90-day summaries without trigger claims, predictions, diagnosis, or treatment advice.
