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.

Reliable, User Friendly, Absolutely Fantastic

I recommend this app to anyone that is remotely having trouble sleeping. I’ve legit been using this every single night for 5 years. I absolutely LOVE that I can set it every night. I use it as sort of a personal check in with myself before I sleep by including some sleep notes about my day to determine the quality of my sleep. The sleep notes are just a a check box that you can select if it applies to you that day. Examples might be: alcohol, tired, sick, worked out, period, traveled, etc. and you can add your own custom sleep notes options! It’s perfect for my short attention span so you aren’t obligated to actually journal sentences, but will have a short reference of the day to look back on months from now.

I also love the quick check in with myself after I wake up! I wake up smoothly over 30 minutes and reach for my phone which gently fades out the alarm which I pick up my phone, no button or bright light required immediately!! Once I actually decide to wake up, the app says good morning and shows me the weather once I stop the alarm, I get to select how to slept also choosing between just three buttons. Bed, medium, or great!

I highly recommend this app and I barely ever review anything unless it’s worthwhile. I pay for the annual subscription but I also used the free version for years. Both are extremely worth it. The premium allows me to keep my sleep data stored forever (or as long as I want).

Worth the subscription!

I pay for very few subscriptions but I use this app so much and it is so incredibly useful that I’ve just renewed for the second year. The statistics you can compile on your sleep are very useful and you can even compare to the national average of your country! I have struggled with sleep for over 10 years and this app has helped to figure out a cause and find a useful treatment option! I could find out the relationship between how much I snore or talk in my sleep and my stress level and sleep quality. The sleep quality percentage even feels accurate so I know the data is real. If I wake up and feel really rested the sleep quality matches how I feel and is always 89% and up. And it’s not all about how many hours I slept! I might sleep the same amount of time and feel very tired, and my sleep score matches that too!

In addition to the data, I use the sleep stories and sleep ambiance every night and while I have my favorites, it’s good to have quite a few options when I want something different. And my favorites never go away so that’s great too! My absolute favorite is “Scents” - I highly recommend it! The guides have a mixture of counting down, guided breathing exercises, progressive muscle relaxation, and soothing descriptive storytelling.

The subscription is a fantastic value as all of this is available for less than $10/month and for a drastic improvement in sleep quality it is well worth it!
