Accurate measurements – the tape holder converts the reading from a straight line to a circumference. In perimeter mode, other tape measures may have significant inaccuracy (up to 0.84 inches), while smart body tape measures offer improved accuracy (as little as 0.01 inches or 0.1 centimeters), providing consistent results. Download the latest application or update to the latest version. Easy to use – the well-made and smooth anthropometric tape is designed with a locking mechanism. Pull out the tape, wrap it around yourself, clip it, and retract it to the correct position until the display shows the reading. It's much easier than using a loose sewing tape. Track your progress – the app records your measurement history and presents it in a clear chart, including 13 body components and 12 body size metrics. By selecting any index, you can view trends by week, month, or year, helping you better understand your body changes. Sync with popular fitness apps – available as a free download on App Store and Google Play. The measuring tape can be seamlessly connected to popular fitness platforms, including Apple Health, Google Fit, and Fitbit. Why is perimeter measurement as important as weight during a weight loss journey? A reliable tool makes a difference. The digital body measuring tape works well with compatible smart scales. Both devices use the same application. Multi-functional tape – useful for weight loss, exercise, waist training, sewing, and clothing size measurement.
