silent alarm clock
lark has been shown to reduce the need to snooze. But if you like to tack on a few more minutes to your sleep each morning, lark makes it simple with customizable snooze settings of up to 30 minutes and an easily accessible snooze notification on your mobile device.
When you set your lark alarm clock before bed, it instantly lets you know how long it’ll be until your lark wakes you up the following morning. Instead of having to do the math in your head, lark helps you to understand how to get the most sleep each night.
The dynamic vibrations are designed to wake even the deepest sleeper, but a composer-written audio back-up alarm will make sure you wake up no matter what.
lark connects to your phone automatically using Bluetooth® connection for transmitting sleep data in the morning and setting the alarm at night.
lark's dynamic vibration pattern gently nudges you awake without bugging anyone else around you. lark's gentle vibration can reduce heart rate variability, stress levels and blood pressure spikes-all of which are known to cause that groggy feeling in the morning.
Used widely by sleep clinics to track sleep quality based on activity, actigraphy tracks millions of micro-movements every minute, and then calculates exactly how long and how well you've slept. Developed with Stanford sleep specialist, Cheri Mah, lark shows you the changes you can make to sleep better.
A bedside sleep journal can never give the detailed, accurate information that the lark wristband captures and analyzes for you. Easily also share your information with a medical professional or even just with friends.
See how last night’s sleep compares to your weekly, monthly and all time sleep data averages. lark automatically calculates averages when your data syncs after each use. You can also see how smaller periods of time compare with your all-time use.
Identify the factors that affect your sleep each night. Whether there was noise outside your window or you had some caffeine late in the day, you have the option to track what’s getting in the way of your sleep or what’s helping you to sleep better.
Whether you are looking to track what you dream about each night or just want to make some notes on the factors that affected your sleep through the night, lark gives you an easy space to keep track of that information.
