Two Apple Watch users recently shared their stories of how the device saved their lives. One of them hails from Wichita, Kansas, where a man named Michael received an Apple Watch as a gift from his son, Nick. The watch notified Nick that Michael’s heart rate had dropped to dangerously low levels. Nick immediately took his father to the ER, where he was diagnosed with a serious heart condition that required surgery. Doctors informed Michael that he would not have survived much longer without the timely intervention. When Nick reached out to Apple CEO Tim Cook, he received a response within two hours, expressing gratitude for sharing the story.

In another instance, a 61-year-old man named Christopher from Asheville, North Carolina, was rushed to the ER after experiencing chest discomfort. Although initial examinations did not reveal any issues, Christopher remembered that his Apple Watch had recorded his elevated heart rate. This information ultimately led to life-saving emergency double bypass surgery a few days later. Christopher also contacted Tim Cook, receiving a response expressing appreciation for sharing the story.

These heartwarming stories underscore the life-saving potential of the Apple Watch, as well as the compassion of Apple CEO Tim Cook, who took the time to respond to these users.
