The Runstar Smart Scale is a digital bathroom scale with 8 electrodes designed for comprehensive body composition analysis. This device measures 28 different body metrics, including body weight, body fat percentage, BMI, and muscle mass, through simultaneous high and low-frequency current measurements on the upper arms, forearms, thighs, calves, and torso. The scale features a weighing surface of 300 x 300 mm with extended electrode pads to accommodate various foot sizes. It displays 7 key metrics immediately after measurement on its bright TFT-LCD screen and highlights differences from previous results. The scale connects via Bluetooth to the Starfit app, which syncs with Apple Health, Fitbit, and Health Connect. The app stores all measurements for tracking progress by day, week, month, or year and allows for the creation of printable analysis reports. With support for unlimited users and up to 24 profiles per Starfit account, this scale is suitable for families and fitness groups. It includes an athlete mode with specialized algorithms for active individuals. The device measures 330 mm in diameter and operates on standard battery power. Please note that Bluetooth pairing in the Starfit app must be completed before measurements, and only one device can be connected to the scale at a time.
