We could all benefit from being a little healthier. This Withings Body Scan's extendable handle uses sensors to scan your body and give you an accurate picture of your composition and overall fitness. It tells you where your fat and muscle mass is located and keeps track of their evolution. Think of it like a personal trainer but without all the shouting. It can also monitor your heart health by looking out for any arrhythmia and checking your standing heart rate every single time you step on it. Can your old bathroom scale do that? And by constantly tracking your nerve health, it can help detect autonomic neuropathies, one of the long-term complications of diabetes.
