Ping Your iPhone From Your Apple Watch

If you misplace your iPhone, you can use your Apple Watch to find it. Provided it's within about 30 feet (if not, use Find My iPhone), the process is simple. Just go to your watch face, swipe up to reveal glances, and then swipe left or right (depending on how you've arranged your glances) to eventually find the Settings glance (shown below). From here, you can tap the large button on the bottom to ping your iPhone. Your iPhone should make a noise, even if the ringer is off. If that's not enough, tap and hold the button to make the flashlight of the iPhone turn on. This can help in the dark. I hope this helps!
