Set Up a Medical ID on Your Phone Lock Screen

Both iPhone (Health app → Medical ID) and Android (Settings → Safety & emergency) allow you to create a Medical ID that's visible without unlocking your phone. Add your blood type, allergies, chronic conditions, medications, and emergency contacts. It takes five minutes to set up and could save your life when you're unconscious and can't speak for yourself. Paramedics and ER staff are trained to check phones for this information. Update it whenever your medications or conditions change.
