A new scientific analysis highlights that smartwatches can misestimate calories burned by over 20% and undercount steps by about 10%, with accuracy varying across activities and users.
Heart rate, sleep stages, recovery scores, and VO2max are also often inaccurately estimated due to reliance on indirect measurements and wrist-based sensors, potentially misleading users about their health and performance.
Despite these inaccuracies, experts advise using smartwatch data for tracking general trends rather than daily specifics, and emphasize listening to personal physical cues over device-generated metrics.
