How we tested and ranked the best smart scales

We weighed concurrently against a calibrated reference scale and compared body fat readings against a DEXA scan for each tester. We graded on weight precision, body comp directional accuracy, app/HealthKit integration, multi-user handling, and price.

How should you read a smart scale: trend, not daily number

The single biggest mistake people make with smart scales is fixating on the daily number – or worse, the daily body-fat reading. BIA scales are best used to detect trends over weeks. Weigh daily at the same time, look at a 7-day rolling average, and ignore single-day swings.

Frequently asked questions about the best smart scales

What is the best smart scale in 2026?

Withings Body Comp overall; Eufy Smart Scale P3 for value; Tanita BC-401 if body composition accuracy matters more than app polish.

Are smart scale body-fat readings accurate?

No, not in absolute terms. Bioelectrical impedance estimates body fat from electrical resistance through your body and is sensitive to hydration, food, and time of day. Use the *trend* – not the number – and weigh at the same time daily, ideally first thing in the morning.

Which smart scale works with Apple Health?

Withings, Eufy, Renpho, Wyze, and most Tanita models all sync to Apple Health. Garmin Index requires Garmin Connect (which can then sync to Apple Health).

Do I need a smart scale to lose weight?

No. But scale weight trends are one of the most useful signals you can collect cheaply. Pair a smart scale with a [weight loss coaching app](/categories/weight-loss-coaching-apps/) like Welling to interpret the trend properly.
