Not working welll with Galaxy S8+. It's motion sensor is way to sensitive and always showing me awake all night with a nearly solid line on top of the graph. No way to adjust motion sensitivity. Worked great on my Note 4. Even put the phone on other side of the bed. When I run the test is doesn't stop making noise. If I put the phone on the dresser is stops and will show no movement. PLEASE fix.

I like that it tracks my sleep and tried to wake me when I'm most awake, I don't notice any ads, and it does what it data it will do. I'm not a fan that it sometimes walled me when I'm coming out of a wakeful time and going back into a deeper sleep and sometimes even asked me in the deepest part of a sleep cycle, but it asked me when I'm at the crest of a sleep cycle like 80% of the time So I suppose that's still pretty successful. The alarm doesn't actively do anything to push you into a wakeful state besides the typical audible alarm Itzel do I have to use other apps to slowly increase sound and light before my wakeup time. Overall this app does wake me up when I'm close to awake most of the time So I'm pretty happy about it.

The app till few years back was one of the best, so much so this was my only purchased app but off late it isn't upto the mark as it always wake me up at the end moment. Say for 6:30-7 am alarm every time it's 6:59, not on everyday basis that should be the case. Need alot of improvement as to sensors
Beth Martin
Incredible app but iOS version is far superior with the mic sensor feature. I was an early premium user for this app on iOS, after using it every single night for years, I switched to an Android. I have been so thrown off ever since because the android app doesn't have the microphone sensor feature. I've even searched high and low for another app thst functions like the iOS version, after 5+alarm app trials, I'm back to the default alarm app. PLEASE, add the microphone sensor feature in as soon as possible, I want my happy mornings back :(

Used to use this app often. But after I recently switched phones, I have to subscribe for features I already had. Northcube got in contact with me and helped correct the situation. As far as the app goes, it's pretty simple and most of the features are self explanatory. The UI is nice and clean. It records your sleep data pretty accurately. I haven't witnessed any major bugs or anything of the sort just yet, even when I was beta testing it. It offers a wide variety of alarms and even more if you buy the app. If you wish to just use it as a sleep analyzer because you have your own alarm, you can disable the alarm and just have it record your sleep. Overall, a pretty solid sleep app.

I really didn't take the time to understand the original intent of this app until the first morning it woke me up. I've been aware of sleep cycles for some time now, but was interested to have some insight into the quality of my sleep because I've always had a very hard time waking up. The first morning, and every morning after that have been the easiest waking up I've had in a long time! Might even consider purchasing.

All you have to do is click on the “I have already purchased Sleep Cycle before”-link on the trial paywall.
Next screen it will ask you for your google order nr (GPA nr) If you’ve deleted the e-mail you can log in to payments.google.com as they save the history forever.
Enter the nr and follow the instructions, and you’ll be premium. For life. I really didn't take the time to understand the original intent of this app until the first morning it woke me up. I've been aware of sleep cycles for some time now, but was interested to have some insight into the quality of my sleep because I've always had a very hard time waking up. The first morning, and every morning after that have been the easiest waking up I've had in a long time! Might even consider purchasing.
I really like the app over all. It looks nice and it works well. I haven't paid for the extra stuff so I'm just using the normal set up. The thing I don't like is you HAVE to set the alarm for it to track your night. I don't always want to set an alarm, like on the weekends I want to wake up naturally but I still want it to track my sleep. I hope they do something about this soon.

Hannah,
This is easily solved!
In the alarm screen, where you set the alarm - top left corner you have a little bell icon, which if you press will make you set Sleep Cycle to just analyze mode, without setting an alarm :)
Thanks for reaching out!
Johan Weirdly, it changed the times after i set it. So I went to bed at 11, wanted to be up by 7, set a back up alarm for 7:15. Back up alarm woke me up, looked at app and it said I went to bed at 10 not 11, I woke up at 6:15 not 7:15, and that I wanted to wake up by 8(!?) So it moved some times backwards and some forwards! Very odd! Interesting to see the sleep patterns tho. Won't be trusting it as an alarm!
Northcube AB May 23, 2017
Laura,
That sounds really strange. Would you mind reaching out to qa@northcube.com so that we can investigate this issue?
Thanks,
Johan I wish the app would take the data and analyze it. On the trends tab, it provides data that's sort of interesting. Sleep quality by days of the week is a good start, but it would be great if I could also see things like sleep quality by bedtime and waketime, etc. I'd also like to see the alarm be just a little smarter. For example, often I'll reach an almost-awake state just before I reach the 30-minute window, and then start to fall asleep again just before it goes off. So many of my sleep charts have me bring basically awake, and then the line begins to fall just before the alarm goes off. The alarm should see that and make an intelligent decision.
I bought this app when I still had my iPhone five so about 4 years ago. Recently switched to android and found it again *finally* cause I really liked the app but now it wants to CHARGE me for features I ALREADY HAD! It told me I could "recover" the receipt code but only if I PAY once a month for the next year, no thanks. I used to use this all the time, really disappointed with what happened to it.
Mainline release does not use microphone (as it does on iOS), which is a big limitation in my opinion. However, the feature is apparently in alpha/beta at present. I assume due to the variety of hardware options out there. 10/10 for support getting back so quick.

Rob,
Would you like to become part of the alpha team to test this feature out? We're hard at work implementing our patented microphone motion technology for Android, and we're constantly looking for dedicated users that would like to take part in our alpha test team.
Reach out to qa@northcube.com and I'll hook you up.
Kind regards,
Johan Wake up so well using this app. I've tried many others - and spent a lot of money in the process - but this app has continued to be the best. For the results, it's absolutely worth paying for the app. Honestly, I don't much care for reviewing my sleep tracking - I only care that it tracks me so well that it consistently wakes me at my lightest sleep and I wake up alert and ready to go. My only mission - to find a product as good as this one where I don't have to have my phone close by or charging every night. If you guys could do that - I'll be yours forever.
Good app that has worked well in the past, but the lack of a microphone option is quite frustrating. Having to put your phone under your pillow every time you go to bed is annoying and makes me worry I might damage it in my sleep. The iOS version has had the microphone option for at least a year now, what's the hold up? I also feel the yearly subscription is overpriced for what it is and that you should instead opt for a one off premium purchase instead.
The app worked really well and I use it every day. However, some recent updates (either to the app itself or with my Samsung S7) have caused some bugs. The intelligent alarm feature is now malfunctioning and does not go off at all. I hope that this issue is quickly resolved so that I can continue using the app.
I sleep an average of 6 hours on the weekdays due to school and on the weekends I sleep an average of 10 hours. I don't set an alarm on the weekends so whenever I wake up, I stop the movement recording. However, I see that it stops recording after 6-7 hours in bed and then labels it as "short nap" with no calculation of the sleep quality or time in bed; it just shows the graphs. I've tried wiping my data and reinstalling the app but this always ends up happening, even with the updates. I hope you can address the root of the problem and fix it.
Very good app. I elected not to subscribe as I'm a little OCD, and I found myself thinking too much about why my sleep quality wasn't perfect. Just easier for me to not have one more thing on my mind, lol. Support was amazing, issued refund right away, no hassles.
The alarm works well. It pleasantly woke me up by the time I asked it to. I was not angered when I woke up, as I usually am by my jarring alarm clock. My only complaint is that it wished it vibrated. I often sleep through my alarm. The app does sense when you're lightly sleeping however.
I love what the app does. Everything about it has helped me get a better sleep higiene. However i am a little nervous about how much the phone heated inside the bed. And I experienced a rise in random crashes and reboots during the day when using it. Not sure if due to the OS update at the time or this app. Cant really tell. Will give it another try.
Had this app for almost 2 years when it kept crashing every time I opened. I had to uninstall and reinstall to get it to work again, but I lost all my data. Now I have to start all over again....
So far it seems accurate. I'm a bit concerned whether or not it also picks up movements from my GF next to me, comprising the accuracy. I'm using it without a fitband. But I like it, wake up is nice and the app is easy to use
Possible bug: Nexus 6P: alarm goes off at full volume, even if you've set it to be low volume in android. Great app and never fails to amaze how it gets it right. Only gripe is the above, doesn't so much wake me up gently when I should be, as blares music at me a foot from the pillow.
I paid real money for this app... the first year was great all features were awesome... until now 80% of the features that were included with what I paid were switched to premium members only. It's a rip off now since those features WERE FREE.
Used the app for years and more recently the beta. Much prefer paying outright for an app but I guess sales for the devs would say differently. If you can justify the hefty yearly subscription for the unlocked features then it's a great app. Unfortunately, I can't justify it.

Tahn,
As a early subscriber you are entitled to premium membership for life. Please reach out to qa@northcube.com so I can help you sort this out.
Kind regards,
Johan Had on iOS since 2011. Had access to everything, all sounds, sleep assists, you name it. Now that all has to be paid for, at $35 a year rather than the one time fee which was I think $2.50, don't quote me on that. The worst part is, I cannot adjust the volume low enough. The lowest setting is startling in the morning, and I am a very light sleeper. That's the biggest gripe. Don't really care about the other sounds, it's an alarm so I've grown to hate all sounds that intentionally wake me up, but the volume... Ugh.
Only used this a couple of nights but I really like it. Such a nice way to wake up! Less annoying than wearing a wristband for tracking on these hot nights. I wasn't sure it would work with my mattress but it seems very accurate.
Was a really good app, worked well until I got a new phone. My old phone was a Samsung s5 and my new phone is a xiaomi redmi note 3. It simply does not work on this phone, either doesn't pick up any movement or picks up too much. Also the last couple nights it has randomly stopped during the night and failed to sound at all. I also paid for premium on my old phone and have no idea how to get it back

Northcube AB May 31, 2017
Logan,
The subscription model only applies for new users. If you've bought the app previously you are entitled to the premium features for free - for life.
Please reach out to qa@northcube.com so that I can help you sort that out.
Kind regards,
Johan Complete ripoff. Went to use it on my new phone and apparently in the time I wasn't using the app, they took nearly every feature and made it "premium" so now I can't do half the things I used to, like select my own alarm music.

Philip,
As an early adopter you do not have to pay again for the app - please reach out to qa@northcube.com and I'll help you sort that out.
Kind regards,
Johan I used this app to track my sleeping patterns and for the alarm features a while ago and I'm coming back to it. Personally, I did not feel any of the positive effects from my previous use. Giving it another shot. I got a fitness band with an alarm feature, the vibrating band has worked better for me personally. If there was a way to sinchronize this apps alarms to the fitness band then... Hmmmmm...... 🤔 Also, I noticed a lot of the features previously available a year or two ago are now locked and require a subscription. That's one way to treat the people who supported your paid app when it was first released.... Huge bummer since my old favorite song is now locked. Anyways I will update on how it works. (3 🌟's because you took away my favorite alarm song)

Johan I have been using this app for a couple days and it helps me so much! I love all of the info it gives you too! The only thing that I dislike is that to use this you have to put the phone in your sheets while charging. This (as I just found out) is a fire hazard. When this is changed I will love it (5 stars) !
The alarm music is amazing and it really does wake you up at your lightest sleep phase. I wasn't convinced before but I'll stir and a few seconds later the alarm will go off - I don't know how but it really can sense your sleeping patterns. The statistics are cool to see - it really can tell when I get up to go to the bathroom or if I wake up for a few minutes. Crazy but awesome!!
This application tracks how deep and long one sleeps. This tracking info does not keep track of my nutrition, but my "deep" sleep is dependent on my nutrition. I will provide this info to my doctor regarding how well I sleep, this info is something my give this a big "thumbs up".
Have been a long time subscribe. But v annoyed that the charging policy is not clear. Sounds that used to be free are now premium. But no way to find what this will cost. Should treat customers with more respect.

Kind regards,
Johan Doesn't work. Graph says I'm awake all night when I sleep well. It keeps waking me up in the middle of dreams, thus in my deep sleep phase, which I apparently never reach according to them. I at least liked the alarm music.
I don't know what happened, but for the last few weeks this app has become completely useless. Half the time it doesn't properly track my sleep and then the alarm doesn't even go off. Doesn't do me a whole lot of good. 😐
Tried to use the app four nights in a row, following instructions and whatnot. At the first couple of days I had to wake up with no alarm at all because my phone was stuck on boot screen. Then tried different configurations, but the app only recorded two minutes up to an hour and a half of sleep. "Smart snoozing" didn't work either. Frankly I'm quite disappointed.
Really like the app but I hate the fact that android is so behind on updates compared to ios?! Sound detection is still not available on android while it has been available on ios almost since the start?! Same thing goes for snore detection! (It s a bit annoying that I have to sleep with my ipad on my nightstand now 😅)

Kind regards,
Johan The app works perfectly. I have used it a couple of times and I always wake up without feeling sleepy. But the main drawback of this app is that it takes up too much battery life of my cell phone.
This is amazing, I've been not to tired or not to awake I've been perfect. I've been more lively and i would definitely recommend lazy people and couch potatoes to use it. It could be better in a way like tell u when u get up or what's better for you.
After reading up on studies regarding sleep rhythm apps, I'm not convinced these things are anything but placebo. However, the interface is nice, and it could certainly be used to track your overall sleep habits with some success, but not any more accurately than just logging your bedtime and wake time in a spreadsheet. Furthermore, this app froze overnight on my Samsung S7 and the alarm failed to go off after it was setup to do so. I was late for work. This is unacceptable. I would highly suggest setting a backup alarm if you're going to use this app anyway. The other nights I used it, it worked fine as an alarm, but there's no way this thing is worth $30.
