  • Audio Effects Feb 15, 2019

    By Twilight523
    I used the app for 2 months and it was great! I usually listen to sleep stories or music because I have a tough time getting asleep. Now, whenever I have an alarm going on, the audio on other apps crashes and you can barely hear what you are playing. The worse part is, the crashing sound it makes is kind of creepy! I know it is the apps fault because when I turn the alarm off, the audio doesn’t crash. Fix this bug and you get an 8 out of 5!! 🤩🤩 Also, I don’t understand why people say there are so much ads. I just pop in and there may be an ad but I just click the X button and don’t mind it. The sleep analysis saying it went wrong, TRY TURNING ON THE MICROPHONE!! I really wish you could comment on app reviews!! I actually don’t even look at the sleep analysis. I just like that it is an alarm that just seems better then the regular one on my phone. I just noticed now why I was waking up later then the alarm had said. It is cool but I would appreciate it if you could turn that function off. Honestly, the reason I got the app was to hear if I snore or not but it is premium and I am not going to pay for something I can probably get for free on other apps. I just have gotten used to this one. Just give us freebies at least an option to change the alarm sound. I am grateful for just one!! So, yeah! ✌︎

    What the heck is wrong with u all? Seriously. Yeah I agree they should make it free forever but it lets u gradually wake up not startle u awake and you start your day struggeling. Great work developers but there is one thing i would've liked to seen. It's where u can hilight a certain area of the audio and make it louder.

    I really love this app. I saw some other reviews saying it has a lot of ads or that it thinks as soon as they set the phone down they're asleep... I haven't had that problem at ALL. I don't think I've seen any ads (or so little that I forgot them) and it shows I'm awake for a while before I actually fall asleep. That could just be because I move a LOT when going to sleep; but either way it's perfect for me. It's also really interesting to see the sleep analysis, I don't know how accurate it is but it seems to be pretty true... and it's really cool to see. And it reminds you how much sleep debt you need to catch up on which is ALSO cool, plus the wake up within a half hour of when you need to be up is nice, as it can pick when you are in the lightest sleep and ready to be woken up. My only issue is that I have to remember to unplug my headphones or else it'll just play in them (I usually listen to music before bed, and often I fall asleep and they fall out of my ears) but thats a small price to pay for a great alarm clock!

  • Very useful but buggy Jul 20, 2019

    This app is great. You set a time to wake up and it will wake you up sometime up to 30 minutes before your set time to try and use what it collects through the night and what we already know about the human sleep cycle to wake you up at the perfect timing for where you are in your current cycle. The issues with this app is sometimes I feel as though the app doesn’t know when to really wake you up because it doesn’t get enough information accurately about your sleep. But in its favor it’s noninvasive (you don’t need it in bed with you) The bugs are just annoying more then a hindrance. Sometimes it’s only buggy when your trying to do something that would be weird like setting your alarm to activate the application for the night while on the phone talking to someone still crashes the app. If you are in the app while on the phone and try to start the alarm for the night after getting off the phone the app will either crash, freeze, or just not respond to the start button. You have to restart it and usually it will work. I get ads even though I’m premium. But rarely and seem to be short ads. When you get a phone call while the alarm is activated if you don’t play or even just have the background noise paused it’ll start playing it when when the call stops. Hopefully the developers can squash these bugs since they been around for a little bit. Happy sleeping sleepzyers!

    I don't think this app is very reliable or accurate in its recordings. I've had a few nights where I've had to get up in the middle of the night, had to tell my dog to be quiet(she sleeps in the room) and there are no recordings. It even has me as in "deep sleep" for one night when I was actually awake. The sleep sounds are good, I enjoyed listening to them to go to sleep with, unfortunately I really want more accurate tracking so will be uninstalling.

  • Data doesn't work Aug 4, 2017

    By Lissibelle
    If someone sleeps well they will think this app works great, but for those who don't, we notice this app just always assumes you're sleeping. I put the phone open right next to my pillow and the test window says it's a perfect place to put it. As soon as I put my phone down it says I'm asleep. It takes at least 30 mins for me to fall asleep once I'm actually settled with my eyes closed. I also wake up multiple times during the night, sometimes getting out of bed for the restroom, none of which it records. So when I get up in the morning (awake before the alarm goes off with it saying I was sleeping-still inaccurate), I'm dead exhausted and haven't slept much but the app says I got as much sleep in as the time it was on. If this app actually worked like it says it does it would be super cool. Maybe work on how to make it responsive to people, and always make it know if you pick up your phone you're pretty much awake. And teach it how to know when someone hops out of bed. Then the app would be good. I rate for content, not concept. Content doesn't work no matter how cool the concept is.

  • Sleepzy Review Oct 26, 2019

    By Thatchickk23
    First of all, let me preface this by saying that I did not even want to buy this app. I got the one-week trial just to see what it was about, did not really use it at all because let’s be honest I just was busy. Anyway after one week the trial ended and I forgot to unsubscribe therefore it charged me for the full year of $40. I decided to give it a try, and soon realize that this app is not very good. I don’t think that it is accurate my heart rate has never dipped down below 60 and it said that my resting heart rate was 40 bpm. I also was not sleeping at the time and when I checked the data it said that my sleep was 86% average and it showed that I actually hit REM sleep, but that is not possible because I was wide awake. This app is not accurate and I don’t think it should be falsely advertised the way it is. Since I did not want this app, I decided to send a message and ask for a refund, to my disappointment I was instantly denied my refund. I don’t think that it is fair, because as a customer I should have the right to get my money back for a product I am not satisfied with.

  • Great app! Just a few suggestions Jun 24, 2020

    By Lily28s
    I really love this app! It’s better than sleep cycle, because the UI is much more efficient and the visuals with the sleep quality help you understand the data more clearly. The data seems to be accurate as well. To people using the app, please use the accelerometer to track rather than the microphone if you want your notifications to come through. I need to use another app to wake me up before sunrise every night. I’ve searched for a long time for an app that allowed me to do that. And I found this one! So thank you!! 👍🏼 Just a few suggestions: First it would be nice if you could have an option to communicate with Apple health to write data about sleep analysis. Second, please also provide an option to put the data together from 2 different sleep sessions from the same night, in case you accidentally close the app, or get up in the middle of the night. That is all, thank you!

    Although I love the app and it's functions, it's missing a few things that would make it so much better. 1. I think it's should be linkable to music playing apps like Amazon music, Spotify, Pandora, and the like. Right now it's "music" option for an alarm is just saved audio files, which for me isn't music. 2. A small thing yes, but I think there's should be an option to turn off snooze. And 3. If it can't link to other apps for music, then it should at least have more options for alarms.

  • Good but sometimes won’t load Nov 22, 2020

    By Teresa Flowers
    Overall it’s very nice. Good breathing exercises, alarm sounds, and relaxing noises to help you sleep. It lets you know how much time you’ll have to sleep when you set your alarm, and offers two methods of tracking your sleep. It wakes me up at the perfect times as well. But the two main things that bother me is that the sleep tracking is sometimes inaccurate. Not by a lot, but it will occasionally record me as being awake for a few minutes when I never woke up at all. The second problem is that when I open the app, it will be on the loading screen and never go beyond that, causing me to have to delete and redownload the app, which is very annoying because then I lose all of the useful info and data I had on my sleep schedules. If anybody knows what causes that, please do because this is the only good free sleep app I’ve found but that is a huge issue I keep having every couple of weeks.

  • Great App for Waking Up Nov 8, 2018

    By MuSiC LoVeR 988
    There’s only two, okay maybe three, downsides to this app. 1) I can’t tell Siri to “turn on the Sleepzy alarm” which really isn’t a downside so much as an inconvenience for like one night where I was too tired to tap tap on my phone. 2) If I’ve had a sleepless night Sleepzy wakes me up close to the minimum time for the allowed range. I’m sure we can all agree when I get upset at getting up after sitting there frustrated I couldn’t sleep 30ish minutes before I would normally get up. Again, it’s a circumstantial thing. 3) I honestly forgot my 3rd most likely circumstantial problem with Sleepzy. Honestly though guys the App is pretty great, free or otherwise. The reason why I am not giving it the full five stars is not because it’s not a great app but because it doesn’t really stick out when compared to similar apps. It gets the job done for free, yes, but it doesn’t offer much in terms of uniqueness.

  • Resolving the problem of battery life. Oct 17, 2019

    By curmudgeonman
    Your recommendation to keep the phone plugged into an outlet all night suggests that your research team hasn’t contacted phone manufacturers for their suggestions. After my iPhone 8 Plus reaches a full charge during the night, it attempts recycling repeatedly to maintain full charge. These attempts drain my long-term battery life. My suggestion: charge the battery to at least 80% before sleep time. Place it near the bed in the unplugged position. This level of charge will power Sleepzy throughout the night and sound the alarm at the appointed time, thus eliminating the permanent battery drain. Research this suggestion and respond to the accuracy of my suggestion.

  • Great app except for the nonstop ads Jun 5, 2017

    By justpostthedamnreviewK
    So here's the thing, the alarm itself is great. I really like the concept and how it roughly tracks my sleep to wake me up within 30 minutes of my alarm (alarm is set for 6am, it will go off between 530-6 whenever I'm in the lightest sleep in that timeframe). I don't know how accurate the sleep tracker is and honestly it's not super important to me. So why 3 stars??! This app has the most annoying amount of ads I've ever experienced and it's an app I use for maybe 10 minutes a day (5 in morning/5 at night). Open the app, AD then wait for the stupid close button to appear (if you get annoyed and start clicking around you'll just open the App Store), set your alarm time oh yay another AD although this time it has a close button immediately, start sleep cycle that's it good night, alarm sounds wake up review sleep data because you're curious AD repeat. Essentially every time I touch this app a full size AD appears on the screen

  • Wish I Could Hear Audio Sep 23, 2019

    By kenzieharman
    I quite literally have used this app every night for the past month or so and had no problems, alarm works fantastic! However, the reason I am leaving 3 stars is because of the free features available (not much besides the alarm) and the function of paid features. After having this app for a month or so, I decided to try the premium trial because I had one night with SIXTEEN recordings, and a 49% quality of sleep. Went through set up, looked at the graphs, and finally, went to click on the audio bytes. App crashed. Okay, whatever, closed out of the app and opened it again. Click on the audio. Crash. I can’t listen to the only thing I wanted the free trial for. If you just want a different alarm than the one on your phone, then this is the app for you. If you want to actually analyze your sleep, I’d look somewhere else.

  • Its okay, but let me explain. May 16, 2017

    By Sng13horses
    I usually don't write reviews for apps, but I felt like I should for this one. I generally like this app, it has a good concept and I like that it can play sounds that turn off automatically after a set amount of time. The downside is, I feel like the "sleep cycle" data it gets from you moving around is inaccurate. For example, this morning I woke up and didn't fall back asleep, so I just laid there, except when the alarm went off about 20 minutes later the chart said I had been in deep sleep prior to the alarm. But I was awake. It also rates your sleep. It often says I got great sleep even though I wake up feeling very tired. Again, I do like this app. It's a good concept, and I really wish it did work, but I don't think it does. That said, I still suggest you get it and try it out. It may work for you.

  • Alas... Oct 13, 2018

    By Ajhand
    Well, it’s a cool idea. If only it worked. I tried it for a solid week to give it a fair shot, but no. Two of the nights it said it couldn’t give me data, so I got nothing. A few other nights it showed me as awake for hours when I had totally crashed. So it keeps telling me about my growing sleep debt. Last night, I was so tired after getting home from a business trip that I didn’t even wake up once to pee (at my age, that’s a rare thing indeed). And yet it shows that I was awake from around 5 am until the alarm went off around 9. I was, in fact, dead to the world when that alarm went off. I’m so disappointed because it seemed great the first night. I like the alarm, and I love the idea of it waking me up at a better point in my sleep patterns. But ever since that first night, it just wakes me up at exactly 2 minutes before the time I’ve set because it thinks I’ve been lying awake for hours. One apparently accurate night out of seven doesn’t cut it.

  • As soon as I opened it Aug 3, 2020

    By Frungi
    Like some other apps, this smart alarm clock offers to track your sleep and set off the alarm at the ideal time of lightest sleep, as determined by a smart watch, in-bed accelerometer, or, in my case, bedside microphone. Unlike the Sleep Cycle app, this one doesn’t work; I often wake up to hear the alarm already going off, whereas with Sleep Cycle, it almost always wakes me as soon as it starts. Sleepzy has an array of other features, some free and some behind a paywall, including sleep aid ambiance, pattern analysis, and “sleep debt” tracking. I used none of these, so they don’t factor into this review. Also, this app prompted me to rate and review it mere seconds after first launch, or possibly first launch years after uninstalling it. Either way, threes no excuse for asking for a eating before the user’s had a chance to use in. Though a developer response did indicate they’d look into it.

How ridiculous 🙄. I know it's silly of me but it's creepy, am a teen that has rough times going sleep and I thought this app was going to be helpful to monitor my sleep but I guess I'll just have to stick with a bed time rule as best as I can✌🏻
