Wildly inaccurate. I was just about to pay for the premium but thought I'd put it to the test. I video recorded my sleep and used the app at the same time. The app said I was I a deep sleep for 4 hours when I can see myself clearly not sleeping. I was a premium user for a year and had my doubts then my subscription ran out. Glad I followed my instincts. You should too

Does not track consistently

Not able to track your sleep correctly, it missed that I woke up during the night and went to toilet, the app registered this as me being asleep. The smart alarm is the only good feature in this app. You get it for free so don't bother buying the annual subscription.

Recent update has made this app unusable. It freezes when opened and is non-functional. Been using it for years and now it's defunct.

not very accurate

doesnt detect noises it should detect. picks up other random noises despite adjusting settings. the support directed me to google play for a refund, but google play directed me back to sleepcycle. so disappointed with this app.

I've been using this app since like 2023 or something... And as of right now? I got Revolut Premium to buy it for me, but I'm like... I'm having nightmares, from just the song alone. I'm trying to wake up, but I was like: "I KNOW YOU CAN HEAR ME. PLEASE JUST LISTEN, AND STOP WAKING ME UP AT THESE TIMES! PLEASE!" but of course it was a dream, so it wasn't audible.

has help me tremendously and is easy to use

long term user. I mainly track breathing and snoring along with SPO2 on my Garmin. Sleep Cycle has been reliable, easy to use and the recordings are helpful.

I used to love this app, but it scared me so bad I had a panic attack. my phone had low battery, so I plugged it in. this app KEPT going off about the low battery over and over even though it was plugged in. I finally had to turn it off because it was freaking me out so bad. now I can't sleep. I cancelled my premium because I can't have a sleep app that scares me. if it dies in the middle of the night, so be it. or maybe alerting just once is sufficient??

zero functionality without subscription

the best app i have ever seen 🫡👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍💘

super useful app. Helps to ensure sleep schedule is good.

You can't even test the app without paying for an yearly subscription. I'm uninstalling it.

They will not cancel my membership and refund my $50 I am not satisfied with this app

pretty good and accurate

Have tried to use for a week now and only successfully managed to record sounds for one night, have tried all the recommended ways to get this to work but seems not to be optimised for Android (Samsung Galaxy 25 Ultra) and Samsung watch 8 classic.

seems pretty good

​The gentle alarm and sleep aids are great, but the tracker is ineffective. It cannot truly distinguish sleep from wakefulness, relying on guesses from the accelerometer and microphone. In my tests, it recorded me as "asleep" while I was awake or even out of bed, and failed to capture speech. The cycle tracking feels like a simple timer rather than analysis of actual sleep data. If you need a real tracker, look elsewhere; I encourage users to test the app for themselves and see the flaws.

As a Chronic Insomniac of 30 years this app is a godsend. It provides something I've wanted all this time. Data. Whilst it won't help my insomnia it allows me to analyse and change my patterns to help.

it's not that informative

Doesn't answer emails I cancelled my subscription within the 14 days and I reached out several times via email and have not received a response. App was ok but was limited when sharing a room.

It does not count sleep at all

helpful and easy to use but I wish the programs wernt so expensive

In my experience, it does not capture awake times accurately, instead it assumes I was sleeping the whole time.

Good app, but a little inconsistent with picking up the sounds during sleep. Sometimes with zero ambient noise, the recording has noise. But, overall a very useful app for overall Sleep analysis and health

I followed there rules for cancelation and refunds however I've been ignored and not given my refund 10 out of 10 would not recommend

Doesn't use any biometric data from your watch. 😂 Just "listens" using your phone's mic? Hehe. What an absolute complete waste of everyone's time. UNINSTALLED

Lots of good things, but always says I'm asleep when awake! Hi app team, my app always thinks I've fallen asleep when I'm actually still awake which is throwing off my data. Anyway to retrain /override that?

amazing! the sleep tracking is spot on and the fact I can use my pixel watch to get more accurate tracking is amazing. one thing though, maybe make the app be able to connect to "health connect"?

I've slept very poorly recently & I downloaded this app to see if it might help. Unfortunately the tracker is just bad. I woke up many times last night, but the only one the app caught was when I fully gave up being in bed, grabbed my phone and went to the other room. Even though I tossed & turned while awake, or even tapped my phone screen to check the time, etc. No log of it. It's like this every night. Also their help docs are underdeveloped and the AI generated pics on their site are creepy.

glad I got it

amazing

Very inaccurate. Says I haven't slept when I've been out for hours. Definitely not worth the sub I got a couple of days ago.

"you have been logged out, login" i neve logged in, in the first place and have no need to make an account stop nagging me every night

Nice app

This is a great sleep tracking app if you want to use your phone. There are alot of options to suite your needs. They even have assements all in the free version. It sync with Google fit (needs to be updated to health connect). I have found the apps very effective at predicting if I'll feel tried or refreshed. If you want deep analysis of your sleep they have a paid premium version. And they offer 7 days free trail. To see if you want to pay or not. Free version will get you the basics though.

tl;dr you are paying for randomly generated plots This app CANNOT reliably detect whether or not I'm asleep. Twice already I woke up in the middle of the night and used the phone to play an audiobook. Both times the app registered it as sleep talking. Regardless, NEVER buy a 1 year subscription to anything! I can't believe I made this mistake.

its a really nice app very useful for America quality and tracking, works live if there was a nap feature

Actually impossible to cancel this God damn subscription. Can't do it in play store (simply doesn't appear). Can't do it on the website because it says to go to play store. Great feedback loop of insanity.

great 😃👍

highly recommend

[1 less star since a YEAR later there's still no Health Connect which would take 30m tops to add with Codex/Claude Code] This app has a great UI/feature-set but is fatally flawed. I use a Galaxy Watch 7 for sleep measurement, but Sleep Cycle *ONLY* uses phone sensor data despite having a WearOS version. This would be fine if it supported Samsung Health Connect, yet the only API is Google Fit, which has been deprecated since 2022 and is shutting down entirely in 2025. 👎

i love this app so much, it finally proved that when my sisters said that i was talking in my sleep true!

stick to regular sleep tracking devices. very easy to start, but tracking isn't the greatest, if you sleep with a fan good luck on the snoring. my watch tracks all this and much much more. Finally got it to link to my Samsung watch and it's not even close. And after I went to cancel, it's hidden in the app, whereas all others are canceled from the play store. 1000% not worth the annual charge. Maybe 30 bucks a year and I'd keep it, maybe.

Very disappointed that it won't track sleep stages (like REM) on Android (only does that on iOS). Otherwise, I like it.

why the price. it's a sleep app not a goldmine bloody hell

I like it and I know how to keep track my sleep for My doctors see my sleep

I want snoring db rate , to know how loud I snore

that app is so good it helps me sleep
