fitness tracker users

Apple is reportedly working on a fitness tracker that has no display, according to a news report circulating online. Details about the device, including its features, sensors and launch timing, remain limited, and Apple has not confirmed the product. The idea of a screen-free wearable from one of the biggest smartwatch makers is drawing attention and debate about how users would view their health data.

New research indicates that smartwatches become less reliable at estimating calories burned as a user's body fat percentage rises. The finding suggests wearables may systematically misjudge energy expenditure for people with higher body fat, raising questions about how much trust users should place in fitness trackers when managing diet and exercise goals.
