From the Manufacturer
The original silent, vibrating alarm clock and basic sleep tracker. Wake gently and refreshed without waking that person next to you. Perfect for spouses, partners, roommates and the hard of hearing.
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
Ever wonder what happens when you sleep? Lark's scientific sleep monitor uses actigraphy to track your movements during the night to tell how long and how well you sleep each night. Instantly see your sleep patterns every morning when you turn off your alarm.
Easily keep track of your mood, sleep triggers and notes on how you slept each morning using the mobile app and learn what factors impact your sleep. You can also see how you compare to your average and other expert benchmarks, and access your data anytime online or through the mobile app.
