Partners who have different scheduled wake-up times, or who just want to achieve a more peaceful rest, may be interested in a new hardware/software combination that works with iOS devices to monitor sleep habits and silently rouse sleepers. The Lark device uses a wrist-strap sensor worn like a watch, along with a charging stand and companion app for the iPhone or iPod Touch (an Android version is in the works) to wirelessly monitor and awaken the user.
