Silent Alarm Clock
Set the alarm on your iPod, iPhone or iPad and the Lark alarm sensor on your wrist will vibrate when the alarm goes off, silently waking you up. The vibration technology in Lark was designed with top sleep experts for a wake up that makes you feel like you woke up yourself, naturally. The gentle vibration can reduce the heart rate variability, stress level, and blood pressure spikes that can cause the groggy feeling in the morning.

Personal 7-Day Sleep Assessment
Lark includes the Lark Up app, which will track your sleep and display your stats on your phone each morning. Lark also includes a free 7-day trial of the Lark Pro app, which will give you personalized feedback on how to improve your sleep, with the option of buying the app after the free 7-day trial period. The app is available from the iTunes app store.
