As my colleague Diego Liarte said yesterday, every time Apple launches a new product a “gate” appears, a problem that usually affects a minimum percentage of users but that goes viral and ends up becoming almost global for most. In the case of the Apple Watch it has been its heart rate sensor that may not work properly on tattooed dolls as confirmed by Apple today on its support page.
Several users have already appeared on Reddit who fail to read their heart rate on their Apple Watch, sometimes not even recognizing that the watch is located on their wrist and stops working. It all depends on the type and size of the tattoo as it seems that tattoos with dark inks and larger are usually the ones that give more problems.
The solution? Apple does not offer a useful solution beyond connecting the Apple Watch to external heart rate monitors if you want to measure this parameter when exercising. Beyond this there are several. For example, if we only have one tattooed wrist and we have problems, we can use the watch on the other wrist and, going beyond that, you can always deactivate the wrist detection as I told you the other day when I talked about how to save the battery.
In any case this is a problem alien to Apple in the sense that is also common in other heart rate sensors and, moreover, it is already known that tattoos are a snag in different scenarios, especially medical ones.
