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.

  • Something isn’t working

    By alex8113249
    I downloaded this with the Curiosity of knowing what my sleep cycle may look like. After downloading, it worked awesome, it was waking me at times in the morning that I honestly felt much better! After about 100 days or so it has stopped analyzing my sleep and the graph looks completely flat lined as well as it wakes me up at the set time I give it every morning so something isn’t right even though I am still doing the same thing I was doing for the first 100 days.
  • Great

    By Bubbles123456!
    I enjoy I can hear myself snore if I do because I honestly had no clue if I did or not. However, it’d be better if I could play music or something in the background.
  • Used to work

    By Momazon
    When I originally got this, I thought it was doing a pretty good job. I’d been snoring and thought this might help me when I speak to my Doctor. But then, it started saying I wasn’t snoring at all. I know I am because I hear myself and my husband also hears me. Not sure what’s up but no longer works. Disappointing since I paid to get the full version.
  • Needs update for crashing

    By Berry61281
    I love this app but can’t use it anymore because even the most recent update crashes when I open the app. Please fix it!!
  • This app failed me on my 2 most important days this semester

    By Polymetrix
    I have been using the Sleep App Cycle for over 3 years, but I’m saddened to mention that I will be deleting after this post. This app failed to work during my finals week and Bachelor’s Commencement Ceremony. I am done.
  • Missing 3 Features

    By GtrInLA
    The first thing we want to know is how many hours actually slept, not in bed which bizarrely isn’t easy to find out. You have to open Apple Health to get that info? #2, where’s the feature to wake you with iWatch? Some of us wear earplugs or don’t wish to wake our spouses.:( #3, life happens, sometimes we wake up, close the app, then go back to sleep for another hour or two... so we have to restart the app and begin a new sleep session, why not add a feature to combine the two sessions? Otherwise it looks like I’m going to bed at 4 am which skews the data. Other then that a solid 5 star.. but after the trial is over I’ll most likely cancel then try others to see if they offer these obvious features that should be included.
  • Battery Killer & Useful Info

    By Kat Pre-CPA
    This app has wonderful information and totally juices your battery! I was charging my phone less than daily before and now I charge it twice daily in the time of a month! It’s hard to decide if it’s worth it or not.
  • Auto sign up for premium

    By deputy anderson
    This app will bill you for their premium if you download it. Even if you don’t specifically say you want premium. I’d go with another similar app if I was going to do it again. 29.99 isn’t worth it when it says it’s free.
  • Wakes you up in the middle of the night

    By Eli_simy
    The first few night I used this i thought it worked great. Then I found some small bugs with it like not being able to have Bluetooth connections while the app is open. But last night I had started the app with lower battery on my phone and I thought well if it dies it’s no big deal. Well boy was I wrong. Apparently when your phone gets really low on battery with the app open it sets off an alarm so i was woken up at 2 am but managed to somehow shut the alarm off in my sleep and yet again the alarm went off at 3 am and I had to wake up and completely close the app. Sooo be cautious about that.
  • Only one thing

    By Paulkarroum
    There is only one thing I would add for the next update. For the sleep aid sounds a crackling fire would be perfect. Everything else about the app is perfect. I used it for about a year now and I love it. I don't use any other alarm clock. It's perfect. Update: Still an excellent app to use. Aside from an added sleep aid I think a better integration of the Apple Watch is key. I really like seeing percentages in REM, Deep Sleep etc. as well as seeing how often I’m “awake”. Many other apps give this feedback once I wake up and turn off the alarm. Plus making the watch play a tone as well for the alarm for us heavy sleepers would be nice!
