See that third of your life you never knew about
A powerful sleep pattern sensor collects information on how well you sleep each night. Based on the same actigraphy technology that has been the gold standard for sleep researchers for the last two decades, the sensor wirelessly sends your sleep patterns to your LARK Up app. The moment you turn off the alarm, LARK UP app shows you how you slept, how long it took you to fall asleep, how many times you woke up and much more.
Improve with your personal sleep dashboard

Ratings & Reviews
I bought a LARK Sleep Sensor over one week ago because I really like the idea of tracking my sleep. The alarm component was also I bought a LARK Sleep Sensor over one week ago because I really like the idea of tracking my sleep. The alarm component was also desirable. Unfortunately, this is a very disappointing realization of a good idea. Consider:
1. The sleep tracking is not very accurate.
2. The bluetooth does not always work, and when it is not working, there is no way to set the alarm. This has already resulted in one nights sleep not being registered, even after spending > 45 minutes (I should have been sleeping) trying to get it to work, following the instructions... the tech support...
3. I can not access the LARK website from my iPhone, which means you can't access the online dashboard. When you log on from a computer, it does not have your sleep history, so no added value.
4. After you buy the LARK, you learn that to get more than the alarm clock and sleep tracking, you have to pay $60 for an annual subscription, which is not at all clear on the sales literature. Based on the inaccurate tracking (assuming it works every night) how can the $60 analysis be correct?
5. The warranty is only for 30 days - not a typo - only 30 days
6. The stand does not "charge your iPhone" but only has a USB port in it
In conclusion, I am taking my LARK back before the 14 day return period is over. The sleep tracking is not reliable. The basic sleep analysis is not available from an iPhone and when you log on with a computer the web site does not have your sleep data. When the bluetooth does not work, the alarm function does not work, which has already failed in the first 8 nights of use (last night). The $60 annual fee, the lack of technical support, and the 30 day warranty don't inspire any confidence. This is a product not ready for prime time. Save your $130 + $60, there must be a better product out there. I am certainly going to look for it. …

Finally! Stay asleep while your spouse gets up!

I keep more "normal" hours. :) He is a he My husband coaches rowing, and gets up at the ungodly hour of 4:30am three days a week. I keep more "normal" hours. :) He is a heavy sleeper and needs a combination of NPR and loud buzzer to wake, neither of which I can sleep through. He was skeptical that Lark would wake him, but Lark has overcome his formidable sleep powers! We've only had Lark a week, but now I can sleep through him getting up... a few extra hours of uninterrupted sleep is huge!
We haven't tried any of the sleep analysis, but just the alarm is worth it! Looking forward to software updates to allow you to set the alarm for different times on different days. …

My roommate manages a bar and gets home at 3 or 4 a.m. and likes to unwind by doing things like vacuuming and cleaning. I have more traditional sleeping hours (12 to 8). I was looking for a way to sleep with ear-plugs in and still be able to be awakened by an alarm. I thought about those lamp-alarms or even rigging a bright light to a timer. I was thrilled to find this. Solved all the problems. Harmonious home now. Got it for the vibrating alarm but the sleep data analysis is useful as well. …

Yes when you have set an alarm for the lark, the software changes to a very dim clock display. This Yes when you have set an alarm for the lark, the software changes to a very dim clock display. This means that the backlight on your iPhone is on all night, which means that you need to have the phone plugged in to a charger or your battery will go flat.
