It’s ok, more for entertainment

I like the program, wish it were more accurate. I sometimes suffer from insomnia and wanted to track how much sleep I was actually getting. This program doesn’t register that I’m waking up in the middle of the night. I’ve taken to taking with me if I get up and walk around, just to have it show up as awake for a minute. When I watch movies for an hour it thinks I’m asleep. I’m watching the movie on the same phone as SleepCycle - you’d think it’d realize something. Apparently according to SleepCycle I get a great nights sleep almost every night. It also thinks I must be doing great on minimal sleep since that’s what I get many weekdays. I wake up most mornings not feeling rested, and don’t sleep through the night, but SleepCycle isn’t going to help track that. Amusing, for that I’d give it 4 stars. I’d give it 5 if it actually tracked when I was awake , and tracked the weather correctly ( massive storm all night doesn’t even show up) and if the air pressure tracker worked. Yes wifi and cell signal on. They need a feature to plug in how many hours of sleep I need at night- I wasn’t born yesterday- and set my own goals for sleep, instead of deciding 6 hours is my ideal, which is unhealthy information to give someone who may not realize only few people need less hours. Tried a couple apps, this one still seems the best at tracking anything.


Really good

I like it’s softer alarm sounds to wake me up. It’s nice to know if you snore while sleeping, and most of the time the sleep cycle thing looks accurate. I find that it’s really off in when you fall asleep (saying I fell asleep immediately even though I stayed up longer) or in waking up (says I was sleeping soundly until the alarm but In reality I was just awake and relaxing) I’ve never really found it to follow any scientific knowledge to wake me up, it just gets me up either at the first minute of my window or the last minute, but that could possibly be due to the fact that I don’t have a bedside table and sleep with it on the windowsill next to my bed. There’s also, I haven’t figured out why, this thing it does sometimes where the alarm doesn’t go off at all, and it just gives you a little silent “good morning!” Notification if you set it up to wake at a certain time. Obviously this doesn’t wake me up. I’ve been lucky enough to just naturally wake up about 10 or so minutes after my alarm each time, but it’s dangerous if you wait until later to wake up. I also haven’t found a way to set it to just repeat on its own every night, you have to manually tell it you’re sleeping now and set an alarm every night. So, I would say SleepCycle is good if you want a gentle alarm to wake you up for things you want to do in the morning sometimes, but not good if you need it for important things you’re waking up for.


Overdue Review

It’s long overdue that I write a review for SleepCycle because I’ve been lucky enough to be grandfathered into Sleep Cycle’s pro version. I downloaded SleepCycle back when I was in high school when it was 99¢ and continue to use it almost every night (10 years later), mostly with the intention to utilize the alarm. I always had at least 2 or 3 different alarms that all failed to wake me up until I bought Sleep Cycle.
I absolutely love that I have access through SleepCycle to different sleep sounds, like ASMR or story telling, because when I listen to things through my laptop instead, it reads me as being awake and talking.
I’ve picked up on numerous hilarious sleep talking incidents with the ability to share the sound recordings with my friends and family, and I love being able to see which days of the week I need to work on getting myself to sleep more consistently and tracking the triggers that lead me to sleep better or worse.
Most of all, though, I appreciate that the company has included me, as an initial investor, in the updates throughout time. Having had the opportunity to realize what SleepCycle does for me makes me think that the least I could do is write them a good review!


Really solid

SleepCycle is great, I’ve had it for years. I don’t have a ton of confidence in the accuracy of their claim for your sleep efficiency each night, but it’s probably not far off. What I love most is the senses you tapping the phone to activate snooze! So you don’t have to grab your phone and try to find a brightly lit little button in a dark room when you don’t want to b opening your eyes—just physically tap the phone anywhere! In fact, I just tap my nightstand and that is enough to silence the alarm for the snooze!

My one big complaint, however, is a change that was made a couple months ago. Now you have to unlock your phone to turn it off. It used to be that the screen would dark all night, but it wouldn’t be locked, so when the alarm goes off in the morning you just see SleepCycle with an off button. But now, the phone auto-locks, so in the morning when it’s time to turn off the alarm, all you see are all the notifications on the lock screen that came in all night. So you have to fight those to get to the unlock, where you can get to app to turn off alarm. Super annoying. It ruins an otherwise nice experience, and does so at the worst time: when you are waking up in the morning. (The developer said this due to a change in policy from Apple, and they’re working on a fix. Let’s hope one comes soon!)


Was the Best, Now Sub Par.

I purchased Sleep Cycle several years ago and WAS a long time Sleep Cycle premium user. Sleep Cycle’s functionality has fallen behind competing apps that have emerged in recent years, many of which have a power nap option built in. The separate Power Nap app this developer sells was last updated FIVE YEARS ago, making it supper buggy and unusable (unless you’re still using an iPhone 3G). Also, the Apple Watch and iPhone apps work independently of one another. So, if you set an alarm on your phone, it will not sync with the Apple Watch app and vice-versa. Sleep Cycle WAS best in class for a long time, and Sleep Cycle still wins on UX IMO.

If you read the developers responses to reviews they seem like a great group... the type of company you want to see beating the competition. Also, they deserve BIG props for allowing their early customers who purchased the premium app to maintain premium functionality after switching to a subscription model, excluding cloud backup. I actually added the subscription service, partly for cloud backup, but mostly because I was so impressed with the way they respected their early customer base when moving to subscription service.

I would go back to Sleep Cycle if updated with the integration power nap functionality, Automatic sleep tracking, Apple Watch heart rate tracking, Apple Watch/iPhone apps sync, and other key functionalities now commonplace in the best sleep apps.


Disappointing and mediocre

I’ve been using sleep cycle consistently for over 2 years now, and I’ve had premium for a year. I’m disappointed to say that even though I’ve always been optimistic about SleepCycle, it’s just not that good. The time in bed compared to time asleep is always inaccurate. The sleep recordings record way too much static background noise. The most annoying thing is that in the last few months SleepCycle has been crashing overnight, so you lose all of the data for that night and it ruins your sleep report. It’s gotten to the point where SleepCycle only works 3 or 4 days out of the week, it’s always really spotty and is no longer reliable. As for the premium features, there is not enough content to justify a 30 dollar price tag. Seeing your data on the graphs is nice, but they are too general and there aren’t enough tools. I want to be able to see biweekly data, compare sleep statistics between months, see different groupings of data besides what’s currently available. I would suggest sticking with the free version of SleepCycle since the data is lackluster, and the nighttime audio recordings never work well. It’s very upsetting having to write this review after using SleepCycle for so long, but it’s ridiculous. Add more content to premium or lower the price. Most importantly, stop your app from crashing.


Not for couples- sadly

I used to use SleepCycle when it was just myself and my cat. Which was rather hilarious when it would mistake her purring for snoring. Hehe. But now that I sleep in the same bed as my partner, who has sleep apnea and thusly snores-a lot-, and also wakes up a lot, SleepCycle isn’t working so well anymore. It’s mistaking their sleep habits for mine. I am a very heavy sleeper and for the most part sleep right through my partners snoring, tossing, getting up multiple times a night (though SleepCycle has recorded me talking in my sleep a few times). But this also means I can, will, and have, slept through **dozens** of alarms. We set them on multiple devices, scattered around the room and even some in the bathroom. I will yell at them, and on occasion simply unplug the device in a half dazed stupor. Then go right back to sleep. For hours. I regularly sleep 14 hours, sometimes more if there’s nothing scheduled the next day.
So—when it was just me and the cat this worked wonderfully! I actually would indeed wake up refreshed, usually, and pretty darn easily too. Perfect for a night owl who was scheduled to get up at 4am for work. Ugh. Perfect for that.

Just…not when your partner snores and gets up every 3 hours and can get back to sleep without watching TV for a while. The poor app thinks I’m awake.


Alien technology!!!

I love waking up early but I struggle so much actually doing it. I literally set about 5 alarms to try to get myself out of bed. And if I don't set an alarm (because I read your body will wake itself up when it has had sufficient rest) i sleep for 10-12 hours.
My first night using SleepCycle I was a little weary about if it would actually work. I set a few other alarms after when it was supposed to wake me up just so I wasn't late. BUT IT WORKED! It went off about 6:20 because I said I wanted to get up between 6:15 and 6:45 and I woke up turned it off and was expected to fight myself to stay awake like norma. This didn't happen. I felt perfectly rest and felt like I had energy all day. I fell like SleepCycle is some kind of alien technology used to give me more sleep in order to prepare me for a study they are doing. Or that this is the technology Batman used in order to only have to sleep 2 hours a night. Even if you are skeptical I would say try it out. I haven't used the premium features that you have to pay for, and with only using the free section this is my opinion. Try it! Just seize the opportunity to easily wake up in the morning. Or spend thousands of dollars on a new mattress. I guess it's your choice.


Doesn’t do the job.

After a month of premium (paid) service this ‘Sleep Cycle’ app isn’t working, and there isn’t any way to contact SleepCycle developers. I set SleepCycle to start recording my sleep and set down my device in the very specific way requested, with it plugged in even, and at some point during my sleep it turns off and records nothing. Last night it recorded 1.5 of the 8 hours I actually slept. I can’t edit to correct a specific sleep cycle. I can’t create records that have only basic information, like how many ours I slept. I have many night that have gone unrecorded and that is the information that goes into their stats. Stats based on incorrect information are useless! So what exactly does ‘premium’ service get me? Nothing. Who cares if I have bad and incomplete information backed up? All the other stats I can easily look up on my own, for free. Don’t buy the premium service. It is a complete waste of money.

I also tried ‘Life Cycle’. It doesn’t track well. You have to fill in a lot of information and that is pointless when the map location is incorrect and, again, SleepCycle doesn’t allow you to edit or correct their mistakes. Incorrect information is useless. Neither app is worth paying for.

Response to app developer response: why would you think I hadn’t already tried the simple ideas? I did that. I rebooted my device as well. None of the easy-fix options have helped. If they had a review like this would just be petty instead of helpful to others.


Not as easy to use as it looks

So it’s not DIFFICULT but I have it set to automatically record but it doesn’t seem to or at least I can’t tell because when I open SleepCycle in the morning it automatically has me set my wake up time and sleep alarm and then stop it. So then I check the sleep journal to see if it recorded at night at it ALMOST looks like I did except I can’t fully see it or access it. There’s a little blurb at the bottom that won’t go away about the journal being there to show what it recorded with the information faded in the background. It makes me feel like maybe that’s just sample information, plus I can’t get the blurb to B go away to really read it or click on anything and everything else is premium. I can’t see stats because that’s premium to figure out if that’s my sleep info or not. And I can’t really read the journal and when I open SleepCycle it looks like I haven’t even started sleeping. Yet somehow my profile says I have records that I can’t find or access…. So is SleepCycle for strangers to figure out my sleeping Pattern via some weird remote monitoring through an app???? Or can I actually use it for my own knowledge? I’ll try SleepCycle for one more week on the chance that it’s user error but if I’m that time I haven’t figured out hope to use it not only will I not subscribe to premium I will uninstall and lower my rating to 1 star. Really hoping I’m just a dingbat because I like the over all look and set up


Should have read more reviews

I can probably count the number of reviews I have given in my life on one hand. It’s just not something I do. But as I’ve aged, I realize the importance of quality products and the need to celebrate them. Or, in this case, the need to express disappointment in something that was once great. I’ve had SleepCycle for about a month and up until the last few nights it has been working really well. So well, that after the first few days I felt I just had to upgrade to the premium version at $29/year (paying for apps is also something I rarely do). Zoom to this morning to me taking the time to write a review even though I’m already late for work, since I woke up for the third time in a row on my own without a peep from SleepCycle , the notification silently displaying, “good morning!” as if it actually did its job. No, you didn’t do your job, app; instead you only captured a portion of the night, or recorded my coughing/snoring but didn’t tell me how long it occurred. Of course my quality was subpar when you think I’ve only been asleep for 3 hours. I could deal with it messing up the recording/data a bit, but when I can no longer rely on the alarm clock *that I paid for*, what good is SleepCycle? This used to be such a great tool. I think that’s what makes all of this worse. Two stars for what it used to be. I guess I’ll be looking elsewhere.


A Life Saver

Am I a morning person? No, absolutely not. Alas, I have a full twelve hour schedule that requires me to be up and ready pretty early in the morning but actually waking the hell up? My body thinks that’s a hilarious concept. I’m naturally a very deep sleeper, but I’m also a night owl who prefers staying up late, so often times I’ll find myself in bed from anywhere between 10:30 pm - 12:00 am and then I’ll have to wake up at about 6:30 am so I can properly get ready for school and then work afterwards. As a college student with 17 credits it’s very hard to not be tired. I decided I needed something to help me wake up easier, since sleeping through alarms or waking up a bleary mess and falling back asleep was just not working for me. I gave this a shot as a last ditch attempt and what would you know? It worked. I just used SleepCycle once, last night at the time of writing this and boy am I satisfied. I didn’t think it would work on me to be entirely honest, but it did and I woke up feeling a lot better than I would’ve with an alarm jolting me awake. This alarm is gradual and soft and even when it’s time for you to wake up it doesn’t fee invasive and obnoxious. I’m looking forward to using it continuously!


Used to be great, but went to garbage

I have had SleepCycle since 2011. I loved it and recommend it to everyone I knew. Regretfully, starting with the last major update, it has gradually undone all the things I fell in love with.
1. User Interface. It’s been about a year since it was changed, and I still cannot get used to the new clunky cartoonish UI, which apparently was designed by a toddler. The sophisticated slick and polished user interface, no more. I figured OK, it’s just a form, let’s focus on substance. Well...
2. The reliability of the analysis and features went down the drain. SleepCycle shows me as being asleep, when I am not, and vice versa. In fact it will show things like snoring and being awake at the same time. Really?
3. Woke me up randomly at 3:30 am instead of 6:30. I kept snoozing it, wondering why I just can’t wake up, to finally open my eyes and see 3:45 on my alarm. HOW? I know I did not make an error. The alarm still shows as being set for 6:30. The only thing I can think of is that I came home from a location with a different time zone (3 hours early) that day. Was this the cause of screwed up internal sleep cycle clock? But cmon. When I set the alarm the night before, the current and the wake times were shown correctly. Needless to say, I could not go to sleep after, and was off my game the entire day. Ironic, that SleepCycle you get to help your sleep, ruins it for you.
I am uninstalling and moving on to other apps. Done with this nonsense.


So disappointed

I’ve had SleepCycle for years and relied on it to wake me up on time and give me insights on my sleep quality with little to no problem. And it did just that, until recently. I set SleepCycle ’s alarm one night, as usual, and went to bed. When I woke, I realized that I overslept when SleepCycle alarm was supposed to wake me. I briefly considered the possibility that I set the wrong time for my alarm. So I open SleepCycle and what I found bewildered me. Not only did it seem like SleepCycle wasn’t tracking my sleep at all the previous night, but ALL of my sleep data was gone. Erased. Years of insights wiped from memory. But I thought, “ SleepCycle is still a good alarm to wake up to” so I used it to set an alarm for the next day. I fall asleep that night and wake up. The sun is shining through my window. That’s my first clue that something is off. I set my alarm for 5 am, when the sky is still dark. So obviously, I overslept again. I open SleepCycle , trying to find some acceptable reason for me not waking up to it, hoping that I was doing something wrong and that SleepCycle that I’ve trusted for years wasn’t suddenly malfunctioning. Unfortunately, it was SleepCycle . Once again, it didn’t seem to be analyzing my sleep patterns and no insights from my recent rest appeared. To top it off, this was the second day in a row that I woke up late for work. SleepCycle has disappointed me in so many ways. The only positive thing is that I didn’t spend any money on this. Do not download.


Neither accurate nor reliable

It doesn’t seem to be aware of when I wake up and get up to walk around (I have Parkinson’s disease with a large helping of restless legs, plus sleep apnea). The wake-up window has never worked for me. The alarm goes off at the earliest possible time, even when by its own metrics I am in deep sleep. Lately it has also frequently stopped tracking my sleep during the night - did it last night , in fact. Simply closes at a random time during the night. Fortunately I’m retired and don’t need to get up for work, though sometimes I do need to wake up for a doctor’s appointment. I’ve started relying on my Apple Watch for actual alarms. The only message I ever get from SleepCycle is something about sleep efficiency. It always gives the same number, and I can find no explanation of what that number means or how it is derived. My sleep is not so consistent that anything should be absolutely the same every single night. I keep using it for the tracking, though I’m not sure why, since it is obviously inaccurate. Also, the labels it gives for sounds are comical (for instance, baby crying, when I am single and in my 70s and live alone). But hearing the sounds is a premium feature, and I’m not about to pay for this, given its shortcomings, so I can’t “improve “ the labels.


nice app!

This is a pretty good app, I don’t regret downloading it. I don’t have the premium subscription, but it’s still good and everything works fine, it’s not like those apps where they give you one feature for free and make you pay for the rest. I’m not sure how effective the wake up window thing is... I often wake up at the very beginning or very end of the window, and I don’t really notice a difference in how I feel waking up using this vs a normal alarm. More often I just use the sleep tracking feature without the wake up window. My only other complaint is the alarm sounds. If I’m not already almost awake (I’ve noticed when I’m on a schedule, waking up at the same time everyday according to SleepCycle I sleep very lightly for like half an hour before) I can sleep right through it. Like, we all like nature sounds but they put me to sleep more than wake me up. And there’s no option for a normal alarm sound or some random jingle in the the Apple clock app. But other than that, it’s pretty great. The graphs are very nice, it tells you how much time you were actually asleep vs in bed, you can even look at a calendar and see your sleep quality over time which is really interesting. Would recommend!


Five-star app with one small shortcoming

What can I say; it’s the best sleep tracking app in SleepCycle Store! Great set of features, very VERY accurate (audio tracking), good HealthKit integration, heart rate support, etc. A few minor bugs linger, mostly due to daylight savings time (UGH!), but not a big deal.
One suggestion: why not allow heart rate optionally when falling asleep as well, rather than when just waking up? I know there are other dedicated apps for this, but seeing as the functionality is already built it, it seems like a natural extension of the sleep-wake “workflow”.
One real complaint (and the reason I rated 4 rather than 5): the inconsistency in the subscription model. I don’t mind paying for continuous cloud service, because it is a continued investment to run. However, for us early adopters, charging full price for sync seems odd — we paid for SleepCycle when it came out, so if there’s no discount for sync, it’s as if we wasted the money buying SleepCycle , and have to pay the same yearly amount as those who got SleepCycle for free. Again, I don’t mind paying for a service, but I would prefer a discounted price. I know early adopters are only a small part of the user-base, but we do still exist! ;)


Changes with Sleep Aid and Alarm Flaws

I generally like SleepCycle, but there are certain flaws that drive me crazy! One of them is that occasionally (1/75 nights at most I would guess) the alarm never goes off. My phone did not restart during the night, and the screen isn’t even off. Once I wake up and move my phone it will start going off, but nothing at all before that, which is incredibly annoying, and has now forced me to add another alarm to make sure that at least that one will go off if this app fails.
The second issue is more of a minor annoyance, and although I don’t claim to know anything about app development, seems super fixable. The sleep aid option used to have an “all night” option, but now the longest you can have it on is 90 minutes. That’s not a huge problem at my dorm because I have a white noise machine, but whenever I go home or travel anywhere it’s super annoying because I either have to use a different app to produce white noise on my phone (which interferes with the microphone-based sleep tracking) or buy a white noise machine to travel with. It just seems like an issue that is so easily fixed, and such a no-brainer, because some people (myself included) will wake up in the middle of the night and not know why, only to realize that the noise turned off!


It is nice when it works but....

Tried this out for a few weeks and tried to primarily use the Apple Watch instead of the phone to see how the watch app works. First, there is no option to change between hours and minutes so you must twist the crown for an unnecessary amount of time in order to change your alarm from 6 AM to 11AM. Second, you cannot use it WITHOUT the alarm which bothersome when you would rather just track the sleep and not use an alarm. Finally, it does not sync to Apple health consistently if using only the Apple Watch. I never slept to the alarm that I set, which was usually set to 11 AM so I would switch it off before the alarm hit. Sometimes it would sync to Apple health but most nights it would not. I would even get an alert on my phone saying it did sync to Apple health then I would open SleepCycle and find that there was no information for that night. Kind of a big strike against a sleep tracker for the watch if it cannot stand alone from its iPhone app when it advertises as such.

SleepCycle for the phone works fine by itself. I didn’t really see a noticeable difference in tracking when using the phone app versus the watch app, however, with all the issues I mentioned above, I am not sure how this ended up an “editor’s choice” when there are some obvious problems with both the design and operation of the watch app.


Bye bye Fitbit

My biggest complaint is I wish the buttons to snooze and turn off weren’t so tiny on the watch. I love the silent alarm but when I’m awoken from sleep (even if it is light), I’m still so fuzzy that it’s easy to cut my alarm off and go back to sleep. Either make snooze a big button and you have to scroll down to reach off, or not allow cutting it off via the watch, just from the phone. The phone should be next to our beds anyway. If nothing else, just make this an option in the settings for those of us who sleep a lot harder.

Otherwise, I love SleepCycle . I LOVE the silent alarms and snoozes. My wife and son love it, too. Now I don’t get them up before the sun rises and I can sneak out to work without waking them. The insights are pretty cool. I did turn off the recording, though. There’s no company I’d let record me sleep. Cool feature if you want it.

When I first got my Apple Watch I was sad about the battery life and that I didn’t have my Fitbit to track my sleep. I love tracking my sleep so much that I was actually wanting my Fitbit back. This is so much better than the Fitbit. The silent alarms are pretty powerful, and the full screen gives you so many more options than a Fitbit ever could. This made me love my Apple Watch. Bye bye Fitbit.


This App Saved My Life!

I have been using the sleep cycle app for almost 2 years now and it has helped my sleep more than anything else. It has also saved my life, hence the title. I upgraded to the premium version and I definitely did not waste my money! Through the morning statistics I found out that I was waking up almost 25-30 times a night and snoring almost 3-4 hours a night consistently. I went to the ENT center and found out that my tonsils and adenoids were restricting my breathing by 75% during the night. I just had surgery two weeks ago and now I do not snore and I am asleep through the entire night! This alarm is intelligent enough that it slowly wakes me up at the time when I’m sleeping the lightest and I wake up feeling refreshed. It also uses Phillips smart bulb technology to slowly turn on your Phillips Hue lights so it won’t jolt you awake. The ONLY issue I have with SleepCycle is that sometime the Phillips Hue setting will not work and that is frustrating when I am accustomed to waking up the “sleep cycle” way. For some reason, SleepCycle can’t locate the lights I have selected. I have tried restarting SleepCycle , my phone, and even the Phillips Main Hub itself to no prevail. However, the next night it could perform perfectly. Maybe the developers will read this and fix it in the next update🤞! I LOVE this application and if you are reading reviews to find out if you want to upgrade to premium...IT IS WORTH THE MONEY!!

It’s ok.

I’ve had insomnia for years. I really wanted to use SleepCycle to track my sleep and habits before bed that influence my sleep. In general, I like SleepCycle . I think it is priced too high annually for what you get. I did buy the premium subscription when it was on sale. I would rate SleepCycle higher if I was able to manually enter my own before bedtime times and my own wake up notes, as opposed to being able to select options from the pull down menu. For instance, alcohol use is known to influence sleep. It would be nice if I could record that I had a glass or two of wine before sleep? Or note that I woke up naturally, without an alarm. Or note that I had extra sugar (chocolate/dessert) before bed, and then woke up the next day with joint pain. There is no where to add personalized notes and I would like to be able to log all the factors that contribute to sleep or lack thereof so I can track everything and discuss with my doctor. Also, under “sleep medicine) I would like to be able to note what I used to fall asleep (I.e. over the counter, prescription med, melatonin, CBC oil or Zzzz). Conversely when I wake, we’re there other factors to record? Am I traveling and sleeping in a different bed? Did the temperature in the room have anything to do with better sleep or lack thereof? All in all, good app. Just needs some tweaks to allow for better personalization.


Kills my battery

While I enjoy some of the features of this watch, as I’ve been testing it for a few weeks before deciding whether to upgrade to premium service, SleepCycle has some issues which lead me to uninstall.
#1 SleepCycle consumes entirely too much battery life. At first I thought it may have been due to older equipment (series 1 watch), but nope, upgraded to a 4 and still uses between 30-60% of battery at night. And that’s with turning screen off and such. Perhaps if There was an option to turn off the microphone, then that could save battery. Or if SleepCycle could base sleep quality off movement detected by the watch it could better use the watch’s features and conserve battery.
#2 I love the idea of the alarm waking intervals - but it’s started spazzing out and waking me up at 2 am!!! Apparently I am not the only one this has happened with recently, which is reassuring, but 2 am alarms are counterintuitive to restful sleep.
#3 paid....subscription?!? How about you just charge a few dollars for SleepCycle , then as you add features, you let those be in app purchases for upgrades? I understand improving apps to stay competitive isn’t free, but paying a few dollars PER MONTH seems a bit over the top.
Overall, decent idea with some intuitive upgradable features, but the APO lacks refinement and customization and the monthly subscription has lead me to try other apps.


Almost perfect

I’ve used Sleep Cycle for almost two years now and I can’t imagine my life without it. That being said, your recent Apple Watch update really needs some work.

I’ve used the Apple Watch app for two days now. The first morning after, I noticed my battery was at 66% even though when I went to bed it was at 100%. Last night it was at 80%, and I woke up to my battery at 29% this morning. This is unacceptable. What is SleepCycle doing that is destroying my watch’s battery? It seems to me like my phone is still the device doing all the tracking, and the watch just reacts based on what my phone is sensing (i.e., my phone detects I’m snoring so my watch vibrates). The only thing the watch app does independently is measure my heart rate, and any of the other sleep tracking apps do that as well without this huge battery drain.

I’ve been using two separate sleep tracking apps because no app did everything I wanted until you released your companion app for the watch. Until you fix the battery drain, I’ll have to go back to that, but I really look forward to any updates you have for this issue.


Heart rate at wake-up still unreliable

For the most part, SleepCycle works pretty well. I was dismayed to see that when they updated SleepCycle to work with inductive charging positions (I.e., the phone is face up), there was no clear indication to not put the phone to sleep. I put it to sleep the first few nights because I wasn’t used to seeing the backlight on constantly (I have an 8 Plus) and awoke to see a slew of notifications saying I needed to wake my phone. While that’s not a huge deal, I found zero documentation.

Also, the update for 8 Plus heart rate monitoring at wake up still rarely, if ever works. I will sit there for at least 90 seconds with my phone starting to heat my finger with the flash because it still won’t accurately pick my heart rate up. My display will go to sleep at least three times all the while, which is useful when I’m super groggy. Needless to say, I turned the heart rate feature off.

It’s been smooth other than that. One remaining question is that when searching the help docs on SleepCycle , there’s no link to contact the developer. I’d never noticed that until I tried looking for ways to alleviate the problems noted above. That seems pretty “meh” for an app I have to pay for every year. I also pay for the Life Cycle app too.


Absolutely positively Love this APP !!!!

I always wake up at night close to hourly, I couldn’t figure out that I was never satisfied in the morning with how I slept or why I woke up exhausted every morning . So I was browsing through just App Categories to find something new to pique my interest when I came across this type of alarm clock that will gradually wake up over the course of 45 minutes instead of just being woken Abruptly and it makes an amazing difference . Every morning when you wake up, you’ll have a sleep report explaining how deep of sleep you were in throughout the night . It tells you why and how many times you woke up and it’s sooo cool that it can do that . There’s so much more too it but the last I’ll mention is that, SleepCycle is not only an alarm clock, it will also pay ambient sounds to help you fall asleep . You used to have to keep your phone under your pillow for it to be an accurate report but now it can be accurate while just being on the dresser next to you . I completely recommended whole heartedly . It’s so well worth the small amount of money you pay to get it .
