The Apple Watch went on sale last week, and people who have tattoos are finding out that their Apple Watch does not work well with tattoos. They went on social media to let other people know.

On the underside of the watch are sensors, and tattoos can confuse them. The watch will not correctly lock, read your heartrate, or read your blood flow. An Apple website says that the tattoos will interfere with the readings but it does not say that it will interfere with other functions.

Difficult words: sensor (an electronic thing that knows when something happens), interfere (to make it hard to do something).

You can read the original story and watch the video in the Level 3 section.
