In an emergency, call 911 (or your local emergency number). If you are in crisis or thinking of harming yourself, call or text 988 in the United States. Do not use this app in an emergency.

Not medical advice

Halo is an automated AI voice assistant. It shares general educational information and practical coping ideas about migraine. It is not a doctor, nurse, pharmacist or other licensed professional, and it cannot diagnose, treat, monitor or prevent any condition. Nothing it says creates a doctor-patient relationship.

It can be wrong

Halo uses speech recognition and an AI language model. It may mishear you, misunderstand you, or give answers that are incomplete, out of date or incorrect. Its content has not been reviewed by a clinician. Do not rely on it for urgent decisions.

Talk to a professional

Ask a doctor or other qualified health provider before you start, stop or change any medicine, dose, supplement, diet or treatment, and about any new, worsening or changed headache pattern. Never ignore or delay professional care because of something you heard in Halo.

Get emergency help right away if you have

This list is not complete. If you think it is an emergency, treat it as one. If you may have taken too much of any medicine, call Poison Control at 1-800-222-1222 in the US.

Use at your own risk

You use Halo at your own risk. See the Terms of Use.
