Withings announces new Steel HR with continuous activity tracking and 25-day battery life

Withings, a company with a solid record of making fitness accessories and connect devices, has announced the newest watch in its collection of smart activity trackers: the Withings Steel HR. While it may look like the company’s previous top-of-the-line activity tracker, the Activité Steel, Withings’ newest offering is packing much more under the hood while keeping its analog watch and stainless steel design.
