If you’re not a morning person or even if you are, but want to wake up with more energy, get Sleep Cycle. I hate mornings. In a perfect world I would be able to sleep 10-12+ hours a night and not get up before 10 am. But unfortunately I am not in college anymore, have a family to take care of and have a grown up job. Before I started using Sleep Cycle I would set at least 10 alarms (on my phone, my iPad and an alarm clock on my nightstand). Even with that I constantly struggled to get up on time and when I eventually got up I had zero energy. That instantly changed when I started using Sleep Cycle. The first morning felt great, but thought maybe I just finally slept good. After using Sleep Cycle for at least 6 months now I can confidently say that it is the reason I wake up on time and with plenty of energy. Before Sleep Cycle I could hit the snooze button and fall right back to sleep. Because Sleep Cycle wakes me up when I am in a light sleep, once I am up I usually can’t fall back asleep. Sleep Cycle has also helped me get better sleep by tracking my sleep quality and identifying variables that cause me to sleep poorly. I hesitate to say any app is life changing, but there is no other way to describe Sleep Cycle. It has changed my life for the better and I am so thankful the developers created it.

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 this app 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, the app can’t locate the lights I have selected. I have tried restarting the app, 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!!

The app 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 the app 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!)

I’ve had insomnia for years. I really wanted to use this app to track my sleep and habits before bed that influence my sleep. In general, I like the app. 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 the app 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.

After a month of premium (paid) service this ‘Sleep Cycle’ app isn’t working, and there isn’t any way to contact the app developers. I set the app 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, the app 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.
