The Xiaomi Body Composition Scale S400 is our best pick for detailed body tracking. At around ₱1,000 as of July 20, 2026, it offers far more data than a plain scale, from a trusted brand, with 7K+ sold and a 4.9 rating.
What does it measure?
It tracks 25 health indicators, including body fat, muscle mass, water content, visceral fat, and basal metabolic rate, alongside weight from 0.1 to 150kg. Everything syncs to the Xiaomi Home app, with room for up to 36 users.
How accurate is it?
Xiaomi says its dual-frequency sensing is benchmarked against DEXA with a 0.93 or higher correlation for key metrics. That makes it a solid home estimate for tracking trends, though not a clinical measurement.
Does the price make sense?
Yes. At around ₱1,000 it delivers premium-style body composition for the price of a basic smart scale. That value is why it is our body-composition pick over pricier rivals.
Who should buy it?
Buy this if you want to track body fat, muscle, and more over time and you use the Xiaomi Home app. If you only need weight and BMI, the cheaper S200 is enough. See our best body scales roundup and the body scale buying guide.
Alternatives to consider
The Xiaomi Smart Scale S200 covers weight and BMI for the same price if you do not need full body composition. The Huawei Scale 3 is a cheaper 10-indicator option.
