Withings already offers the Pulse wristband for tracking your activity day and night, including sleep. But the new Aura pair of devices goes further, obsessively poring over every detail of your night. The sensor slides under your mattress and monitors your body movement, breathing cycles and heart rate. The bedside device measures noise, temperature and light levels, and works as an alarm clock, using colored LEDs to lull you to sleep and wake you naturally. You can listen to music stored on your phone. All the Aura sleep data can be examined in an app (iOS only) alongside data from other Withings wellness gadgets.
