You can’t predict when you are going to be in an emergency, but you can predict, to some extent, how you will respond when you are in one. Apple wants to help you out with the latter. Today, at the company’s annual Worldwide Developers Conference (WWDC 2016) in San Francisco, Apple announced its new SOS button for its Watch OS3.

The feature enables users to call emergency services by pressing the sidebar and holding it down for several seconds. Depending on what country you are in, the Watch calls the emergency services number specific to that country. Once help is on the way, the Watch will also be able to send a message with your location to some or all of your emergency contacts.

On top of this, the Watch can also now display needed medical information, acting like a medical alert bracelet. If you use the emergency services feature, the Watch will then display the emergency medical information that you had previously entered into the Health app on your iPhone.

Already, Apple’s voice activation service, Siri, can help you call for help with just your voice, as one woman, Stacey Gleeson, recently found crucial when her baby needed medical attention and she had dropped her phone, reported Fortune.

So if you are stuck in an emergency, having an Apple watch on your wrist or phone near you might make getting help that much easier.
