If you’re thinking about getting a wrist tattoo, your Apple Watch may not be able to detect your pulse — but it’s fixable with some money and pain.
An Apple Watch could have trouble with a user’s tattoos
The Apple Watch, like many other wrist wearables, relies on light to gather data points about a user’s heart activity. However, users with tattoos on their wrist can sometimes find that the sensor doesn’t work all the time.
In a post to TikTok, a person is seen undergoing a laser tattoo removal procedure on their wrist. A tattoo sleeve covers the wrist, which causes the Apple Watch sensor to fail.
