Tattoos and the Apple Watch: an inkling that they’re not the best of friends…

If you thought your grandparents were the only ones who might not like your tattoos, you may be surprised to learn that the Apple Watch doesn’t sit well with them either.  This came to light recently and Apple have acknowledged the potential interference in their online Apple Watch support section:

“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 ink in the tattoo has been reported to interfere with the heart monitoring feature of the Apple Watch in particular.  The Apple Watch heart sensor uses different grades of light to monitor blood flow through the wearer’s skin but tattoos, particularly tattoos with darker blocks of colour, can act as a barrier and prevent detection of your heart-rate.

As the Apple Watch is designed to function only when worn against the skin, wrist tattoos can also cause the Apple Watch to lock, requiring frequent entry of the passcode to reactivate the device.

One tattooed Reddit contributor guinne55fan documented his experience with the Apple Watch.

The watch would lock up every time the screen went dark, and prompted me for my password. I wouldn’t receive notifications. I couldn’t figure out why… I decided to try holding it against my hand (my left arm is sleeved and where I wear my watch is tattooed as well) and it worked. My hand isn’t tattooed, and the Watch stayed unlocked. Once I put it back on the area that is tattooed with black ink, the watch would automatically lock again.

So if you are considering getting an Apple Watch, you better WATCH out for that ink on your wrist!
