Hi guys,
i’m contemplating on buying an apple watch series 7, but i’m wondering if the light sensors work on dark skin?
i happen to have a tattoo on my wrist, but i wish to use the sensor for biological data gathering.
what are your experience with the apple watch on dark skin/tattoo?
cheers,
andreas b
Apple Watch Series 7
Apple says;
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.
You can turn Wrist detection off but there is a downside;
Turning off wrist detection affects these Apple Watch features:
When you use Apple Pay on your Apple Watch, you’ll be prompted to enter your passcode when you double-click the side button to authorize the payment.
Some Activity measurements are unavailable.
Heart rate tracking and notifications are turned off.
Apple Watch will no longer automatically lock and unlock.
Apple Watch SE and Apple Watch Series 4 and later won't automatically make an emergency call even after it has detected a hard impact fall.

Dark skin, yes. Tattoos, probably not.
Does apple watch series 7 work on dark skin?
