In a bid to catch up with Apple’s health info natively included in the iPhone, Google has added similar functionality in their latest version of Android. This info is found under settings and there are 2 different options there. One is the option of adding in an emergency contact which can be anyone on your current contact list. The second is to add in health info.
This info allows the phone owner to put in their name, address, blood type, allergies, medications, organ donation status and other medical notes like allergies.
There is a warning that this information can be seen by anyone on the lock screen. On the lock screen this info is found by clicking emergency and then a button comes up to tap into emergency contact info. See the screenshots below!
