Wake up gently and silently

Never jerk yourself awake or wake your partner again. Lark's dynamic vibration gently nudges you awake without bugging anyone else. Waking to vibration can reduce heart rate variability, stress levels, and blood pressure spikes, all of which are known to cause that awful groggy feeling in the morning. Wake up naturally instead of alarmed.

A look at how you sleep
