Since its release, the Pixel Watch has often been criticized for its lack of health features compared to Google-owned Fitbit wristbands for several years. Moreover, the Pixel Watch looks pretty unreliable in terms of health, as we have seen, for example, that it is completely wrong in measuring calories.
Fitbit watches have had a big advantage over the Pixel Watch so far. Sense 2, Sense, Versa 4, Versa 3, Versa 2, Versa Lite, Charge 5, Charge 4, Charge 3, Luxe, Inspire 3, and Inspire 2 were able to send irregular heartbeat notifications that worked when you were inactive or asleep. and It is now up to Pixel Watch to take advantage of this feature.
Indeed, according to reports from Google support pages, some users were pleasantly surprised to receive erratic rhythm notifications in the Explore tab of the Fitbit app, even though the watch is not officially compatible with them.
It remains to be seen if this is just an error. or if Google offers the feature to your watch above the line. When cheaper Fitbit watches have been offering this feature for a while, it seemed surprising that it failed to deliver such notifications.
