Quick verdict
The Wyze Smart Scale X measures 13 body composition metrics plus heart rate — a rarity at this price — on an elegant ITO-coated glass surface, with a 400lb capacity and baby/pet mode. A 22-month battery and app with trend tracking complete the package. It is the best-value smart scale for data-curious households.
Key features of the Wyze Smart Scale X
The standout is heart-rate measurement from a standing scale — a feature usually reserved for models costing several times more. Combined with 13 body composition metrics (body fat, muscle mass, water, bone mass, BMI, metabolic age, and more), it delivers a full health snapshot in seconds.
The ITO-coated glass gives a sleek, seamless look with no visible electrodes — just step on. A 400lb capacity accommodates more users, baby/pet mode weighs little ones by subtraction, and multi-user recognition keeps everyone’s data separate.
The Wyze app tracks trends over time with clean graphs, and the 22-month battery life means you will change batteries roughly once every two years — set it and forget it.
Who the Wyze Smart Scale X is for
Value seekers who want the metrics of a $150 scale for far less. Multi-person households benefit from user recognition and baby/pet mode. Wyze ecosystem owners get unified app convenience alongside their cameras and sensors.
It is ideal for trend-trackers — people motivated by watching body-fat and muscle numbers move over months, not by single weigh-ins.
What to watch out for
Budget bioimpedance has budget accuracy — treat composition numbers as trend indicators, not lab results, and weigh under consistent conditions. The heart-rate feature is a nice extra, not a medical monitor; it does not replace a wearable or cuff.
The scale needs the Wyze app for full features, and data lives in Wyze’s ecosystem. Athletes with very low body fat may find standard bioimpedance algorithms less accurate for their body type — athlete modes on premium scales handle this better.

Wyze Smart Scale X FAQs
How does it measure heart rate?
Through sensors in the scale’s surface that detect your pulse while you stand on it — similar in principle to the optical sensors in wearables, adapted for the feet. It is a wellness metric, not a diagnostic one.
What is baby/pet mode?
Weigh yourself holding the baby or pet, then weigh yourself alone — the scale subtracts to find their weight. It is the easiest way to track infant growth or pet weight at home between vet visits.
How accurate are the body composition numbers?
Reasonably accurate for tracking trends over time; absolute values can vary with hydration, meals, and time of day. Weigh first thing in the morning under consistent conditions and follow the trend lines.
Does it work for multiple users?
Yes — automatic recognition supports multiple household members, each with private data in the Wyze app.
How long do the batteries last?
Up to 22 months with typical use, thanks to efficient power management. That is among the longest in the category.
