Libra is the scale that measures body weight, body fat, water percentages, muscle mass, bone mass, BMI and more. Via Bluetooth, the Libra connects with your Libra app on your smartphone (iPhones, iPads, and Androids) to calculate accurate readings then you can analyze from the ease of your phone, and better yet you can set custom goals that the Libra scale will recognize. It’s not just a one person device, it can read and calculate data for up to 8 users so get your friends and family involved, and pursue that active, healthy lifestyle.
