Waking up made easy Sleep Cycle is an intelligent alarm clock that tracks your sleep patterns and wakes you up in light sleep - the natural way to wake up, feeling rested and energized. No need to place your device in bed - Sleep Cycles uses sound analysis sleep tracking. How it works • As you sleep, you go through different sleep phases, ranging from light to deep sleep and back again. The sleep phase you are in when your alarm goes off is critical for how rested you will feel when you wake up. • While you sleep, your movements vary depending on what sleep phase you are in. Sleep Cycle’s patented sound technology tracks your sleep patterns using sound or vibration analysis, monitoring your movements in bed throughout the different sleep phases. • Sleep Cycle finds the optimal time when you are in light sleep to wake you up in the morning, during a predefined 30 minute time window that ends at your set alarm time. Waking up in light sleep feels like waking up naturally without an alarm, leaving you feeling rested and energized. • All you need to do is turn Sleep Cycle on before going to bed, and place your device on your nightstand or close by on the floor. Continuously rated as the best smart alarm clock on the market.

  • Nope

    By beckyg4au
    Disappointed that there is suddenly a subscription fee for this glorified alarm clock. I’ll move on to something else.
  • Was a great app until the last update

    By Darwin33
    I’ve really enjoyed this app, the basic features that came with it were just right. In the last update they took all of it away without even a warning. Now it’s useless. Time to try a different app.
  • Big disappointment

    By Msuzuki
    The app recently took away all the features the users were enjoying for years. I’ve used this app for years, probably since shortly after it became available. They’ve added features, and fine tuned the app along the way. I’ve been there all along. Then suddenly, without a notice, the app’s features are all taken away except for one, no not even one, just part of one feature. Now it’s a simple alarm clock. All the historical statistics I’ve accumulated over the years are now inaccessible. They’ve taken that away. All the sleep notes options are gone. Not even the alarm sound choices are available anymore. Ive diligently used this app for years and accumulated my historical data. They won’t let me access it nor have new data accumulated UNLESS YOU PAY A MONTHLY SUBSCRIPTION FEE. It’s not even ‘buy a premium version’, it’s an ongoing subscription of $3/month. What a betrayal to their loyal users. They won’t even let you access YOUR statistics that you’ve already accumulated in the past that WAS freely accessible. Ive never been treated this horribly by any software makers. What a rude treatment. Greed. Unethical. A big mistake. I regret I had the automatic update enabled for my apps. A big mistake. If they wanted to go on a subscription base, they should have applied that to new users only and they should have grandfathered in their long time users. You don’t take away what you’ve already offered for years.
  • Used to love it

    By Rai-Rain
    Used to love it and it worked great for waking up gently. However recently it’s been on the fritz and will go off whenever it wants. I always wake up pretty consistently the same time every morning but recently the alarm has started going off at all hours- 2AM, 5AM, 6AM, 11AM. Hours before I should be up for work or hours into me already being at work, but somehow not at the time I set it for. Bafflingly, the alarms persisted sporadically even after I stopped using it for a few days and switched back to a normal alarm. The alarm from this app still would not give up. I rage uninstalled the app yesterday as I’ve been been very sick and finally got a day to sleep in. And what was I woken up to? You guessed it, this alarm. (Still, oh so conveniently, not going off within the time range I normally wake up) I should mention also that the sleep analysis features have also been in a fritz, but honestly those are less invasive to my sleep and were just a nice bonus, so I care less about those stopping to work. In general, used to be a great app? I used to highly recommend it, but after a couple weeks of severely interrupted sleep I just can’t trust this app anymore and I’ll be looking for a new one.
  • Needs Do Not Disturb override

    By Jomigo
    I would give this 5 stars, but for me one big glaring problem. It does not sync with iPhone’s Do Not Disturb actually overrides it and will automatically not allow any notifications to come through. I want all my Favorite Contacts to be able to text or call me, regardless of hours. Family emergency? It won’t come through. Teen child out late and needs a ride home? Won’t come through. I love the functionality and charts and for that reason alone gave it more than one star. But until they sync with the native Do Not Disturb functions of iPhone, it will not get 5 stars from me.
  • Crazy accurate

    By Connor Tefft
    Works really well
  • The things that do work work well. The things that don’t work are annoying.

    By LondonMyst
    I’m a Premium (paying) user. I don’t know that Sleep Cycle is worth paying for, however. My app is updated to its most current version, yet problems remain. (One of the problems that I find the most annoying is that I had Sleep Notes enabled so that the app could track my sleep more accurately and note patterns which could affect my sleep. On the nights that I select “Ate Late” the system states that I “Worked Out”, instead. I have now toggled off “Sleep Notes” (one of the features I PAY for) because it is useless. Another feature which does not work is also in the “Trends” section of the app (and is the main reason I wanted to use “Sleep Cycle.” The “Decreased Sleep Quality” section has never updated with ANY information. It says that five nights of data is needed (I’ve used the app for over two months) and that a minimum of one Sleep Note is required. (I had over two months of Sleep Notes entered...which I have now toggled off since, as I mentioned, above, the app fails to translate the Sleep Notes I have created, accurately.) At this point I am paying for features which I wanted to utilize, but those features do not work. If it continues, I will not remain a Premium user (since there isn’t a point in paying for something that doesn’t work as advertised) and I’ll uninstall the apps. (Both Sleep Cycle and Life Cycle since neither app functions, properly.) That’s a significant problem since I’m a paid user with both apps.
  • Inaccurate

    By k-em
    I used this app a few years ago after quitting a stressful job to see if my sleep was improving. It seemed to work well and I liked it. I deleted it when I felt like I no longer needed it. Recently my sleep has been adversely affected by illness. I have no trouble getting to sleep initially but wake up and often can’t go back to sleep. So I put the app back on my phone to try and get a record of when I wake up and how much sleep I get. However, it’s not accurate. As I type this it’s 5:30am and I’ve been awake since 3:00am. Looking at the record of my sleep it doesn’t show me waking up until about 4:30-4:45am. I have to wonder if it’s recording my husband’s sleep instead of mine. I move around in the bed regularly but I also lay still trying to go back to sleep.
  • They listen!

    By Eapatches
    I couldn’t view my trends and the app told me I needed to pay $30 to access over a year of my sleep info. The developer reached out to explain how to restore my purchase, which I really appreciated. This is one of the best alarm clocks I’ve ever used and the data behind how you sleep is incredibly valuable.
  • Upset about the costs

    By Jeff Boyle Group
    I have used this app for almost 4 years just about every night and I really like following the data.I look at it wit to see how what I did affected the quality of my sleep. That being said, I am very irritated that suddenly have to pay $30.00 a year for wait I have been getting free for 4 years. No way am I paying $30.00 a year for this. I used to tell everyone about it and how cool it is to be able to see this information and now I will not be able to recommend it. $30.00 is outrageous. It's ashamed that they ruined such a good app.
