A smart scale is a digital weighing device that measures weight and various body composition metrics like body fat, muscle mass, and water percentage, typically syncing this data to a smartphone app for tracking.
Most smart scales use Bioelectrical Impedance Analysis (BIA). They send a weak, safe electrical current through your body; the speed at which it travels helps estimate different body composition components.
While generally consistent for tracking trends, the absolute accuracy of smart scales can vary based on hydration, time of day, and scale quality. They are best utilized for monitoring progress over time rather than precise medical diagnosis.
Individuals with pacemakers, implanted medical devices, or pregnant women should avoid using smart scales due to the electrical current involved in Bioelectrical Impedance Analysis (BIA).
