    LARK review

    • Written by from Oakland

    409 of 464 people found this useful

    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.

    I am hearing impaired and I've always look out for a new and improved alarm clock. This exceeds my expectation as I love its wireless so I can put my iPad/iPhone away from my nightstand. This device gets me up on time better than other vibrating alarm clocks. I don't know if you market the deaf community, but they would appreciate LARK greatly! Thanks.

    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.

    Using it for two months. Works pretty well.

    • Written by from Carson

    45 of 46 people found this useful

    I'm posting this review as a counterpoint to the low scoring review by GD.

    First of all I am not related to Lark at anyway. Just a normal user like everyone else.

    I've used the Lark for more than two months (got it end of September, writing this on Dec 7). Here's my thoughts:

    1. The Lark sensor works and works well. The sleep sensor captures the data pretty well but it's not 100% accurate. I would say about 95% is about right, which is pretty decent. I don't agree with GD as saying "it is not very accurate" but then again we may have different ways to interpret that. I would dare say for most people it's at the very least accurate enough, more accurate than most people will think.

    2. I can access my data on my iPhone. In fact, that's the first thing I do when I wake up, to check how much I slept right after I turn off the alarm. The same data can be accessed when I go online. Heck, I can even access it in my iPad Lark app. I don't understand how GD cannot get the data; this is the most basic thing this Lark is supposed to and if it that doesn't work I'd return this right away.

    What I did notice is that the iPad Lark App is TERRIBLE! It's simply the same Lark in the iPhone but it's not even pixel doubled. It sits in a small window in the middle of the screen, and there's no 2X button to make it bigger. To the Lark guys, the iPad gives you all this space and it's not being used. Hope this gets better in the future.

    3. Sleep coach: Yes you pay $60 for the sleep coach. But to be honest? Never needed it. I'd be curious to see what the sleep coach can do but just by looking at your own sleep data you can pretty much guess what the sleep coach will tell you anyway.

    4. It is true however, that the cradle does not charge your iPhone when you dock it. The cradle simply has a USB port. You put you charging cable there, you put the other end on the iPhone. So there's a cable sticking out from your dock connected to your iPhone sitting on the dock. It's not the prettiest and elegant solution, and it seems the images are a bit misleading since they don't show the cable, but it works.

    Finally, the big question: Should you buy one?

    As I've said I've been using it for the last two months. In all my years I found that Lark is the best experience for me to wake up: waking up via a vibration on my wrist is much much more pleasant than waking up to an alarm. I like it so much that when I travel, I bring the whole system with me. I don't use the room service wake up call or the room alarm, I use this instead.

    In addition, seeing your sleep data is really enlightening. I've been more conscious and more aware of my sleep patterns and it has really encouraged me to sleep better.

    Yes the thing's a little on the expensive side, I wish it were a little bit more cheaper, but given that I'm getting better sleep these days and a better experience waking up, if I had to buy it all over again, i would. At least for me, it was definitely worth it.

    When it works it's GREAT...when it doesn't...can't be relied on.

    I have a love the benefits the Lark system provides when it's actually working. My sleep has improved immensely, it's saved my job, and my sanity on more than one level.

    That being said, you REALLY have to be careful with it. BE SURE that the connection is solid when you go to bed so that at least the initial alarm is set. Snooze doesn't always work, because the device doesn't always reconnect its bluetooth connection when the alarm goes off, so sometimes Snooze will work, sometimes it won't...so it will pay for you to have a second (audio) alarm set as a backup...just in case.

    It doesn't work as designed, though on paper is an excellent idea. It works, to a point and it does have its flaws. If anyone could ever get those worked out, you'd have a superb product.

    Package design is great and the product has great potential BUT

    The product needs work. The first night, the battery ran out in less than 5 hours, the 2nd night, it would not allow alarm to be set (Bluetooth connection made but the app said it was.not connected). I doubt a connection between this and another app enabled accessory purchased at the same time, but neither worked. If you are going to give it a shot, I recommend purchasing online unless you live close to an Apple store.

    hasn't woken me yet

    • Written by from SAN FRANCISCO

    45 of 51 people found this useful

    The vibration is very weak. Much weaker than an iPhone. Thus far in four tries it has failed to wake me. Most recently it claims to have lost bluetooth connection during night even though phone is at side of bed and plugged into USB charger. It may work as a sleep monitor, but very disappointing as an alarm clock.

    Great product, a vibrating-alarm and sleep coach in one

    • Written by from San Jose

    For someone like me who has strived for years to get more sleep, the last month with Lark has been wonderful. If you're like me and you just think to yourself "I gotta get more sleep," then what I've found is that nothing changes. An occasional sleep-in is nice but what I really want to have is someone at my side reminding me and giving me more clues about how I've been sleeping and what I can do little by little to improve.

    When I started using the Lark vibrating alarm, I found the instant daily feedback (via the accompanying iPhone app) was great. Not only how many hours of sleep, but how quickly I went to sleep and how many times I "woke up", which I presume it measures using motion sensor in the device itself.

    I like the product because it has some cool features:
    * a vibrating alarm that doesn't wake everyone up, just me. And an iPhone app to set alarms (similar to the native alarm feature of iOS)
    * a daily set of stats on my sleep: duration, how many times I tossed-turned, and even "how fast I got to sleep", and Overall sleep rating "good" "poor" etc.
    * a sleep-coach assessment that looks at patterns over a 7 day period with a very detailed and useful write-up at the end with helpful hints
    * a reminder (iPHone notiication) that it's time to go to sleep - sounds funny but this actually helps!

    So overall I've been able to use the Lark in 3 ways: as a daily alarm clock, as a daily sleep data collector to keep monitoring how "well" I'm doing according to some personal goals, and as a sleep coach with more in-depth assessment data.
    The only improvement I'd look for in the future is that some mornings the iPhone doesn't connect to the device to shut off the alarm -- and I need to dock the device and wait for bluetooth to connect before I can just switch the alarm off. Overall a superb product.

    I no longer worry about sleeping thro my alarm

    • Written by from Concord

    36 of 41 people found this useful

    I am a surgeon and also significantly hard of hearing, My early arising always woke my wife, since I had to set it loud to even hear it.. And when she was out of town, due to frequent business travel, I slept poorly even with the clock radio turned way up, for fear of over sleeping. Those days are over, and I feel I am sleeping much better, since I am not stirring every half hour to look at the clock. I find it extremely reliable and compact so that it is easy to pack for travel. All other clocks for deaf and hard of hearing (bed shakers, light flashers, etc) seem totally barbaric in comparison. I'm very pleased!

    Not impressed, 30-day warranty shows lack of confidence in product

    • Written by from Calgary

    47 of 64 people found this useful

    Have had Lark for under a year and it is toast. Only 30 day warranty? Are you joking? For a $100 item I expect more, especially from Apple. I own a Mac, power Mac, three iPhones and an iPad and to purchase such a product that is not consistent with these devices is dissapointing. Features great, actual product quality horrible. Will be more cautious to buy cheaper items from Apple. Thought they could do no wrong, but they did. Don't buy the Lark, not worth your hard earned money.

    Only alarm that can wake me up consistently!

    • Written by from Gainesville

    I've struggled with alarms failing to wake me up for years. No matter how loud the audio alarm, I was always jolted awake enough to shut it off and fell back asleep. I bought the Lark without expecting much better results. I was VERY wrong. The USB port for charging is a big plus- keeps me from using too many outlets- and I had no connection issues at all. From the first night I used it, I could tell this was a keeper when I woke up with the alarm in the morning. It woke me gently and without startling me. And it did again the next day. And the next. And the next. 3 weeks in and I've woken up with it every single day I've used it! The wristband took a little bit of getting used to, but it's comfortable. All in all, a well thought out system that I wouldn't hesitate to recommend.

    LARK

    My previous alarm clock was loud. Really loud. It woke up everyone in the house. Except me. When I heard about the LARK, I decided to give it a chance. It did not disappoint. I wake up on time. I don't wake anyone else up. My sleeping habits are becoming more normal. In short, the LARK performs as advertised. If you have any of the sleep related issues I mentioned, you should definitely consider buying a LARK.

    Teaching an engineer how to sleep right

    • Written by from Mountain View

    28 of 30 people found this useful

    Prior to using Lark, I would never work to change it because I didn't HOW poorly I slept. Lark works for me as a wake-up mechanism! It is so nice not to sleep through twenty alarms and lie in bed exhausted for an hour after I wake up before I get out of bed. This has been a problem for me since I was a teenager.

    Also, now I UNDERSTAND how poorly I'm sleeping because of the analytics. It really drove the point home when I could see the data in front of my eyes. I didn't fully understand how bad my sleep schedule was because I was just trying to stay awake as much as possible to work, and would end up often sleeping on a couch or in my room with the lights on.

    The coaching is useful too because it gives me clear suggestions on how to adjust and improve instead of just telling me "Your sleeping is horrible." For the first time I'm actually excited about improving my sleeping habits.

    Get out of the dark on your sleep stats

    • Written by from Venice

    24 of 25 people found this useful

    When I heard about Lark I knew immediately that I needed one. I rarely use the Un-Alarm clock - although it's certainly a useful feature. As someone in the early stages of diagnosis for sleep apnea, the Lark sleep sensor was a great way for me to get a handle on how much sleep I was actually getting and how often I wake up through the night. And as the parent of a toddler, it was really helpful to get a handle on how little sleep I was actually getting. Sleep is essential, and with the feedback that you get from the sleep sensor (if you're disciplined about using it) you can really challenge yourself to treat your body better and get more sleep.

    I bought the lark simply for the silent alarm clock. I was interested in the technology but it wasn't by primary reason for purchasing the Lark. The Lark has proven to be a great tool for understanding how sleeps (or lack of) affects me when i am awake. Everything works as promised and the iphone app is intuitive and informative. Great product.

    Good Idea on paper

    • Written by from Granger

    30 of 41 people found this useful

    Tried this product and although it did wake me up the first morning, the vibration is rather weak and likely not enough to rouse from a sound sleep. Could not get any of the sleep data to appear on the phone. You have to keep the small unit plugged in all the time except when wearing it. Was tricky to get the bluetooth to consistently connect. Good idea on paper but it is being returned.

    LARK

    • Written by from Seattle

    So here's the scoop on the LARK. This gadget detects motion during sleep. That's it. I've used it 3 times now. The first night I slept 8 + hours and it told me that I slept, "Very Well". The second night I slept 4 hours and again it told me I slept, "Very Well". I did not sleep well either of these nights. The third night I got up before the alarm and shut the alarm off. The alarm ended up coming on during a phone conversation I was having. As for going to sleep, the lark told me the first night that it took 15 min and 8 min the second night. I know these two times for going to sleep were way off. ALSO read all their RETURN POLICY before buying. I'm now in the process of trying to return the LARK and get ALL my money back. There will be a follow up to this review. Hope APPLE is reading/listening.

    For $100 - - very UNIMPRESSED!

    • Written by from Vancouver

    22 of 26 people found this useful

    Actually, for any cost, I'm unimpressed.
    The first night, I set it up, I used it, but it couldn't get into my account because apparently my password was wrong. Tried to reset the password, was prompted that a new password reset would be sent to my mail. Never arrived. Tried again a few days later, email never arrived. Even switched email addresses thinking it was an error in my email... still nothing.

    In the meantime though, you can use it solely as an alarm rather than sleep tracker. So that's what I did. Set the Lark, with a backup just in case. I was not lulled out of sleep in the morning. I was jolted by how strong the vibrations were.

    Next night, tried it again. No back up alarm. The battery died and suffice it to say, did not wake me up and I missed the first 1.5 hours of work that day.

    It has now been 10 nights, and it has not lasted through the night yet. Went online, and this is a topic of theirs on their troubleshooting tab, so clearly I'm not the only one. Says to update the app. Well, there's no update available for that app.

    So far, very annoyed that LARK would create, and apple would selling something so unreliable. Waiting to hear back from the email to their support staff.

    I had a problem with my LARK sensor (dog chewed it up), there were no similar problems on the FAQ's. I contacted tech support. They were helpful and very timely in their response. It's nice to know LARK backs up it's product with more than just talk. The alarm is intuitive to use and performed as advertised.
