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.

For the money, genius!

Third update: still brilliant, still doing everything I said before. Love that they keep up with updates and improvements (although I didn’t see any issues, the ability to play music even with headphones, is definitely a plus). Thanks Sleep Cycle for waking me up pleasantly for so many years.

I have been using this app for years & everything I said in my original review below, still stands. The new feature of having the phone by the side of the bed is brilliant! I did have the phone drop on the floor on occasion in the past so the new method is much better for me. The people at Sleep Cycle are brilliant for creating such a useful & clever app & it is definitely worth the money. Don't hesitate.

59p to ensure you wake up fresh as a daisy every morning? Why not take a chance. After using this app for a week I am both delighted and amazed. I love seeing my sleep-graph every morning & tracking the amount of sleep I've had & the quality of that sleep. I have struggled getting up in the morning for my entire teenage/adult life but this makes it much more pleasurable. I have a memory foam mattress, and it still works like a dream ;)

Wake ups are easy!

I’m in love with this app! I originally bought it way back when and didn’t really get along with it at the time. But, about a year ago I invested in some Philips Hue bulbs, so, thought I’d give the app a go again as the idea of waking to slowly brightening lights during the darker months was super appealing. It didn’t disappoint! What I also love is the amazingly calming yet super effective wake up sounds which have kept me using the app even though I’m not using the Hue bulbs anymore. What I hadn’t expected to find helpful was the sleep tracking, but knowing whether I’ve been able to get to sleep quickly, whether I’ve stayed asleep and whether it’s been restful have really helped with my sleep and mood disorders. My only disappointment was having to pay again to use the backup and sync feature, as all my other premium features came across great.

Don’t like do not disturb

I have been using this app for just over a week now. Though I’m not entirely sure I trust the trends that it’s recording, I do definitely feel better waking up, less like, urrgghhh and more like I can actually get up in a reasonable time. I do think all the premium stuff would be good, but I’m not paying that much for it!

One thing that is bugging me, and I think needs to be changed, is the do not disturb feature. I have missed a phoned call from the ambulance service this morning relating to my brother, and only discovered the voicemail 6 hours later! There are NO settings in the app that I can turn this off. While I understand why they put this into the app, they need to let users decide whether to use it, and I already use the Apple do not disturb settings, which allows me to pick and choose what calls and notifications come through already. It’s enough to make me not want to use the app for fear of missing something like this again!
