Shortly after the Apple watch became available, #TattooGate started trending on Twitter, where tatted watch-wearers complained of inaccurate heart rate readings, the watch not sending notifications and, perhaps most annoying, locking up.
"Many factors can affect the performance of the Apple Watch heart rate sensor," the Apple support page explains. "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 good news is that lighter-colored tattoos don't seem to mess with it as much - if at all. And if you do happen to have dark wrist tattoos and you waited in that long line to score yourself an Apple watch - don't worry, there's a solution for you, too - and it doesn't involve removing your tattoo.
According to Apple's website, it's as simple as getting an external heart rate monitor, such as a Bluetooth chest strap, and you should be good to go. Or, you could just move it over to the other wrist if you don't have any ink over there!
