Some Apple Watch users complain about heartbeat sensor delayed data after Watch OS 1.0.1 update

Apple put a lot of fixes and changes into its Watch OS 1.0.1 update.

It might need a few more.

A number of users as well as independent testing have reported that the Watch OS 1.0.1 updated has caused some Apple Watches to track heart rate sporadically, in some cases with an hour or more between readings, according to complaints on Apple’s support forums, and verified by AppleInsider’s array of tests.

The Apple Watch owners first cited complaints about the issue on Wednesday, noting that Apple officially states that the Watch should take a reading every 10 minutes outside of the Workout app. In some cases the Watch is not only taking much longer to obtain a reading, but failing to do so at all unless wearers launch Workout or an appropriate Glance.

Workout tracking appears to functional normally for the most part, although one poster on Apple’s forums said that during a bike ride his Watch was stuck searching for a heart rate, something he’d never seen prior.

In one case, the Apple Watch hadn’t taken a heartbeat reading for several hours.

Apple has so far experienced a mixed public reaction to the Watch’s heart rate sensor. While the technology has made the Watch a pick for a handful of medical trials, the company was also forced to admit that it may not work at all with wrist tattoos. In spite of this criticism, the sensor has been praised as both accurate, reliable and essentially on par with the Mio Alpha, a dedicated heart rate tracker also worn on the wrist.
