When your alarm goes off in the morning, is your first reaction to throw it against the wall? The problem isn’t with you—it’s with your alarm clock. Thankfully, Sleep Cycle offers a clever solution for improving your rest. Rather than yanking you from your slumber at a specific minute, the app analyzes your sleep patterns, then picks the moment you’re sleeping lightest (within a half-hour window you define) to rouse you gently. Best of all, unlike some smart alarms, this one doesn’t need extra hardware or require your device to be resting on your bed: It tracks your sleep using just its microphone.

Outstanding App of its type

I was one of the first people to buy this app many years ago and still use it through many upgrades. I’ve purchased and installed many similar apps, including ones attempting to use the Apple Watch to detect sleep state and they all fall short of Sleep Cycle. This app is precise, reliable and simple to use as well as loaded with features. (You don’t want to be setting up buggy apps in both phone and watch, unreliable alarms makes you anxious) Moreover the displays of sleep state and snoring sounds are easy to understand. Sleep cycle uses algorithms working of the microphone and has always worked through air conditioning sound even those noisy portable units for me. You can switch it to use the motion sensor in which case you must leave the phone on the mattress. The snooze alarm is brilliant because the snooze intervals shorten each time, making it impossible to overs snooze and resets by simply moving the phone.

Very good but one suggestion

So it all very good you know how it listens to your sleep and has the sounds but there is one problem where I think it really needs to fix. It’s the alarm. Now don’t get me wrong the sounds are great, the thing I want to talk about is how it goes off there isn’t an easy way to turn it off. I have used it for 2 nights and both times when I have woken up the alarm has gone off and I couldn’t turn it off. When you turn on your phone you can’t just click stop like with a normal alarm, you have to go into the app and swipe it or something like that. In the morning when it wakes me up, I don’t always think straight when I first get up. When it goes off I have to frantically turn it off so I don’t wake up my family (we wake up at different times). The second night my Touch ID wasn’t working so I had to put it my password quickly getting it wrong twice. I then went into the wrong app. I than just gave up and turned my phone. Making mornings hard which is the whole point on why I got this app so I wouldn’t be. So I really hope you can fix this
