About this item: 1. OFFLINE TREND DISPLAY WITHOUT PHONE: Unlike most smart scales, this scale shows 6 key biometric data and trends directly on the screen even when not connected to a phone. Gradient trend curves visualize daily changes in weight, body fat, and muscle mass while displaying current BMI, heart rate, and body type. Dynamic arrows compare measurements to your last reading for easy progress tracking. 2. MULTI-USER SHARING VIA QR CODE: Perfect for family health management. After creating a profile in the companion app and completing the first measurement, simply scan a QR code to share the scale with up to 8 additional users via their smartphones as sub-accounts. The scale intelligently identifies each user and securely manages long-term body data without requiring phones during measurements. 3. RECHARGEABLE DESIGN FOR LONG-TERM USE: Say goodbye to constantly buying and replacing batteries. This smart scale features a built-in lithium battery rechargeable via included Type-C cable.
