There have been a number of reports this week that tattoos can affect some of the sensors on the Apple Watch and now Apple has confirmed this.
Apple has now updated its website relating to the heart sensor on the Apple Watch and the company has now confirmed that tattoos may affect the sensors.
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.
Apple suggests that if you are not able to get an accurate heart reading from your Apple Watch, then you can use the watch with an external Bluetooth Chest strap.
If you have a tattoo and are looking at buying an Apple Watch, it might be a good idea to go and test one out in the Apple store to make sure it works.
