The Withings Pulse is the latest device in the personal activity tracker category, and it isn’t a wristband, which runs counter to the latest fad. Instead, it’s a portable rectangle not unlike the original Fitbit devices designed to be carried in a pocket or attached to clothing via an included clip. The Pulse fills out Withings’ line of home health monitoring gadgets, pairing up with its smart scales to deliver info about steps walked, calories burned, altitude traversed and heart rate.
