Use Your Apple Watch as a Flashlight
Believe it or not, your Apple Watch can also work as a flashlight, although it’s less effective than your iPhone.
Instead of using the flash of a camera, your Apple Watch will use its own display and turn it into a flashlight. What’s cool is that you can tap your screen to make the light brighter or dimmer, depending on what you need.
Granted, this feature will work better if you have a more modern and brighter Apple Watch, but even on older models, it’s still powerful enough to help you out in a pinch.
