The Withings Pulse can monitor its activity, differentiating between uneven and stroke, sleep (it is not doing evil to detect waking hours, when they are accompanied by movements francs), and to measure heart rate ( with relatively little difference compared to a heart rate monitor). Well designed (its battery allows it to last for days without recharging), light and easy to use, it will satisfy all those who, like me, have a goal in weight loss and shape retention.
