Editors’ Choice

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).

i love sleep cycle

I literally use sleep cycle every single night. i’ve been using it since 2014 (i was 11 at the time) and have never looked back. i fell in love with it immediately. i remember when there were only the four alarm noises, i still use the same alarm noise i did when i was 11, the sunrise one! if this app ever leaves the appstore i will die 😂 no but fr i love this app and it’s so fun to look back at all my nights of sleep. right now i have 1,237 nights, but i suspect there is a lot more that’s been lost between the switching of phones. the current tally of nights is from 2019 to present. i wish i had all my data from before but oh well! i use premium and it’s definitely worth it for me, but i can understand where others might not feel the same. it is expensive but as a long time user i rely on it heavily and really enjoy it, it’s part of my routine. a feature i would really love to see is the total time spent in each sleep phase (i.e. deep sleep, sleep, awake) there’s the graph that kinda shows you, but i would love it if there were numbers to break it down (i know it wouldn’t be 100% accurate numbers lol but just an estimate would be nice even) otherwise, i am really happy with the app. thanks for all the years you’ve put into it, developers!
