Medical ID on Your Wrist: The 10 Minutes That Can Save Your Life
Last verified: August 2026
Medical ID is a small screen that shows a paramedic your conditions, medications, allergies, and who to call — even when your device is locked. It takes ten minutes and can matter enormously.
What Medical ID Is
Medical ID is a built-in card on your phone and Apple Watch that lists your important health information: medical conditions, medications, allergies, blood type, and emergency contacts. Crucially, it can be viewed without unlocking the device — so a first responder who finds you can see it and know who to call.
On Apple devices you set it up once in the Health app on the iPhone, and it automatically appears on a paired Apple Watch. On Android phones there's an equivalent emergency information / Medical ID screen reached from the lock screen.
It's one of the highest-value ten minutes you can spend on your phone, especially for anyone living alone or managing several conditions.
When to skip the DIY and just call: You're not sure what to fill in · You want it set up on the watch, phone, and a spouse's phone too · You'd like it checked so it truly shows from the locked screen.
Common Questions
1 How do I set it up on an iPhone / Apple Watch?
- On the iPhone, open the Health app.
- Tap your picture (top right) → Medical ID → Edit.
- Fill in conditions, medications, allergies, blood type, and emergency contacts.
- Turn on "Show When Locked" and "Share During Emergency Call," then Save.
- It now appears on your paired Apple Watch too.
2 How do first responders actually see it?
- On an iPhone: from the locked screen, they slide to the passcode screen and tap "Emergency," then "Medical ID."
- On an Apple Watch: press and hold the side button and swipe the Medical ID slider.
- That's why "Show When Locked" must be on — otherwise it stays hidden.
3 What should I put in it?
- Your main medical conditions (heart, diabetes, epilepsy, etc.).
- Medications you take and any serious allergies.
- Blood type if you know it, and your primary doctor.
- One or two emergency contacts with their relationship (e.g., "Daughter — Susan").
4 Can I set it up on an Android phone?
- Yes — most Android phones have Emergency information or Medical ID in Settings under Safety & emergency.
- Fill in your medical info and emergency contacts and enable showing it on the lock screen.
- The exact menu name varies by phone brand; I'm happy to find it on yours.
5 How often should I update it?
- Review it whenever your medications or doctors change.
- Check it once a year, perhaps when you change your clocks.
- Make sure your emergency contacts' numbers are still current.
