Apple has finally responded to complaints that tattoos can affect the functionality of its new Apple Watch. Late Wednesday, the company quietly updated a support document to note that users with wrist tattoos may have trouble getting reliable heart rate readings from the device.
Apple has issued no official comment on the issue, though comparisons of its current Apple watch support document and an archived version show the addition of a paragraph warning users that tattoos could hamper the Watch's performance.
"Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance," the updated version reads. "The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings."
Some tattooed Apple Watch owners have also reported problems with the device's "Wrist Detection" feature. Apple's update only notes issues with its heart sensor.
