Best Smart Body Scales for iPhone (2026)

As an Amazon Associate we earn from qualifying purchases.

Quick answer: A smart body scale measures weight (and often body-fat, muscle, and more via bioimpedance) and syncs the trends to your iPhone and Apple Health. Get a body-composition scale for full metrics, a simple weight-only scale that syncs cleanly, or a multi-user scale for the household. Apple Health/HealthKit sync and multi-user support are the features that matter most.

Pro tip — bioimpedance body-fat numbers are estimates; track the trend, not the daily value. The body-fat and muscle figures from any consumer scale are rough estimates that shift with hydration and time of day — don't obsess over a single reading. Weigh at the same time daily (morning, after the bathroom) and watch the multi-week trend instead. Also confirm it syncs to Apple Health specifically, not just the maker's own app.
