There is an app that is pre-loaded on iPhone and available for Android that could save your life or the life of someone you love.
It is the Health app,
which includes Medical ID. You can use Medical ID to list the
names of your emergency contacts, their phone numbers, special
instructions, your health ailments, and any medications you are
taking or allergic to, that emergency personnel should know
Paramedics may not have
time to access this information on your phone in an emergency,
so it is not meant to replace a medical ID bracelet. However, if
time is available, emergency personnel usually know they can
swipe for this information.
For iPhones, Tap on
Medical ID > Edit. Then turn on Show When Locked. This
ensures that first responders can see your medical information
even when your iPhone screen is locked. To make an emergency
call or to see your Medical ID, wake up your phone by swiping
left to right > tap Emergency > make emergency call or tap
Medical ID to see the stored medical information.
For Android users
solutions vary by manufacturer. Under Settings, look for an
Emergency Contact-type feature. It may be under My Information.
If so, fill in your medical information and emergency contact
To add an Emergency
Contact to your phone lock screen, tap Settings > Lock Screen
> check mark Owner Info > Tap the small icon to the right
of Owner Info > type in your emergency contact name and phone
number after owner name. This information will scroll across
your lock screen even when it is locked.
