We validate smart scales against clinical standards like DEXA scans and bioelectrical impedance analysis (BIA) when possible. Each device includes confidence ranges (±2% to ±5%).
Beyond basic weight: body fat %, muscle mass, bone density, visceral fat, hydration, metabolic age, and app integrations (Apple Health, Google Fit, Samsung Health).
Comparisons include special considerations: pregnancy-safe modes, pacemaker compatibility, athlete accuracy, and beginner-friendly interfaces.
Every comparison explains how devices were tested, what was measured, and the limitations of each method.
