RunStar 8E SmartScan Pro Review: 28 Metrics, No Heart Health Tracking

The RunStar 8E SmartScan Pro is a mid-range smart scale that measures 28 body metrics. It separates fat and muscle measurements across five body zones: arms, legs and trunk. Seven metrics, including weight, heart rate, BMI, body fat, muscle mass, bone mass and body water, appear on its color display; the Starfit app shows the full set.

The scale uses eight electrodes and dual-frequency bioelectrical impedance analysis. RunStar says each metric is DEXA-validated with at least 98.5% correlation. In TechRadar’s testing, almost all results fell within a reasonable variation compared with the more expensive Withings BodyScan 2.

It has pregnancy and baby modes that use what RunStar calls zero-current technology. The scale supports multiple user profiles and can automatically identify a user based on previously recorded measurements. Its 5 x 7 cm TFT-LCD is clear and bright, but a thin plastic cover can flex when pressed. The scale has 6 mm tempered glass and a rechargeable, non-removable lithium-polymer battery; a full charge lasts three months, according to the review.

The review notes that the scale lacks heart health reporting, including heart rate and blood oxygen tracking, despite heart rate appearing among the seven displayed metrics. It lists a $219.99 price, often discounted, and describes the 8E SmartScan Pro as a solid alternative to more expensive models for users who can do without heart health measurements.
