Choose if	You want a low-cost scale that tracks weight trends and sends body readings to the Wyze app.	You want Withings' app, Wi-Fi sync and body composition readings from a scale without a handle or ECG.
Main trade-off	Wyze gives no accuracy figure that names the Scale X, and only weight and body fat show on the scale while the app holds the rest.	It reads through the feet only, Withings publishes no accuracy figure for it, and some people must switch off its body-fat readings.
Key specifications	Body composition method: Bioelectrical impedance through 4 electrodes in the glass surface. The Wyze app shows 13 metrics: weight, body fat %, heart rate, lean body mass, BMI, muscle mass, muscle mass %, visceral fat, basal metabolic rate, bone mass, metabolic age, protein and body water %. Only weight and body fat show on the scale Weighing: Four independent leg sensors. Range 11 to 400 lb (5 to 180 kg).

Operating temperature 41°F to 104°F (5°C to 40°C), storage -4°F to 131°F Use guidance: Bare feet on both electrodes for body composition. With socks or shoes on, the scale measures weight only.
