Apple admits the Watch doesn’t work well with tattoos

Luke Dormehl for Cult of Mac:

On the Apple site, the company now notes how, “Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance.” In terms of an explanation it claims that, “the ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings.”

This isn’t unique to Apple. Other devices with similar technology, such as Fitbit’s Charge HR, are affected by the same issue.

“Tattoogate” unbelievable.
