Pairs with your Siqo plan
The best smart scales, compared
A smart scale gives you the weight (and often body-fat, muscle and water estimates) that Siqo uses to calculate your calorie and macro targets. We compared five well-reviewed, widely available models on price, tracked metrics, connectivity and battery life.
Weight readings from these scales are reliable. Body-composition numbers (fat, muscle, water, bone) are useful for spotting trends over time, but they're estimates — not a clinical-grade measurement.
