A support page on Apple’s website confirmed that some tattoos can disrupt the Apple Watch heart-rate sensor.
Reports surfaced in recent days that the Apple Watch ran into trouble for some users whose wrists had tattoos. On Apple’s website, a page dedicated to monitoring heart rate cites several factors, such as motion and blood flow, that can disrupt the reading. Tattoos are one of them:
Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings.
The page was updated April 29. Apple didn’t have additional comment beyond the statement on the support page.
The problem doesn’t affect every person with a tattoo using the wearable. Whether this will be a big deal for buyers depends on whether they are drawn to Apple Watch as a fitness wearable. The Journal’s Joanna Stern recently wrote that fitness bands just can’t compete with the emerging class of smartwatches.
Apple’s support page lists other ways people can measure heart rate. The blog 9to5Mace arlier reported the update to Apple’s support site.
