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.

I’ve always had trouble trying to get up in the morning from my normal alarm so I decided I’m just going to get a proper app. I was looking for some good app that will help me and I came across sleep cycle. It looked really good and had great features I tried it for the first few days and it was great!! I happily woke up in a light sleep and I actually was ready to get out my bed instead of my normal alarm which was insane!! I also love how as soon as you wake up if tells you have long you slept for unlike other sleep apps you have to wait along time just to find how long you slept that night?! Sleep cycle is just so easy to use and is absolutely great for people who have trouble waking up in the morning! Even though I don’t have the premium it still works great and fine! So I am very impressed with how great this app is! Question- Does sleep cycle still work even with people sleeping in the same room near your phone or can it mess up the cycle a bit hopefully not because I have roommates how like to snore and I hope that doesn’t affect anything!!😀 5 stars!⭐️⭐️⭐️⭐️⭐️

Here’s why I deleted it after 4 years

So I’ve used this app for about 4 years with the subscription. It is a very good app. I love the data I have built up and it gives some insight. That said, the data is also pretty useless. Over time my sleep quality scores have gone up, but my sleep hasn’t changed. The scores it provides have gone up because the app learns YOUR sleep and gives you boosted scores when it knows enough about your sleep, you know after 4 years. I always score like 90+ in the later years of using it. This means that ALL of the data from years gone by is useless as the room for error in the new data has reduced. It is the most unscientific experiment ever. Afyer 4 years I can tell you the main benefits of this app are the wake up window and audio recording.
The rest for me is a gimmick. It doesn’t work well in partner mode. It’s sleep scores are not accurate, I’ve often felt like I’ve had the sleep of my life and scored 60%. I believe a healthier sleeping pattern involves waking at the same time each morning, something this app discourages with its wake up window (this is optional tho), and also not incorporating a smartphone into your sleeping. Keep your phone away from your sleep area. Since I’ve stopped using the app and started waking at the same time each morning with a normal alarm, I feel much better. I enjoyed the app, but I do not believe it has any positive effects on your sleep and if anything encourages poor habits.
