Apple Watch is great for health and fitness tracking; we all know that. It houses almost every sensor a smartwatch can compile and backs them up with superb applications. Most of the sensors are located at the back of the watch, where you might’ve seen a green light blinking all the time. And if you’re one of the persons annoyed with the constant flashing and wondering how to turn off green light on Apple Watch, this is for you.

The green light on Apple Watch is the heart rate sensor. Since it’s an inbuilt sensor that runs while wearing the watch, the light is turned on all the time.
