### 4/5 — 배터리 소모 심각

*2026-08-28*

몇년째 유료결제해서 쓰고있는데 근 일주일들어 밤에 배터리 소모가 심각합니다. 예전에는 안그랬던거 같은데 한 30퍼센트 남은채로 충전기 안꼽고 앱 켜고 잠들면 아침에 폰이 꺼져있을때가 부지기수입니다. 확인 부탁드립니다

### 4/5 — Needs option to hide sleep data

*2026-08-27, version 6.26.32*

Love the app. I use it for the alarm clock functionality, waking me up in the lightest part of my sleep cycle in the morning. What I find very stressful is, upon waking and turning off the alarm, immediately seeing a page of my sleep data. Could the app please be adjusted so that there is a “data lite” version / “alarm only” interface, for those of us who are anxious about our sleep? (With the option to unearth the sleep data IF we want it?)

### 4/5 — Recent loading problems

*2026-08-27, version 6.26.32*

Loved the app and it’s been my main alarm since 2018. Recently the app refuses to load after opening. Even after updates. Very frustrating

### 4/5 — Oh Well

*2026-08-26, version 6.26.32*

I have been using this app for many years but I can no longer afford it due to the price increase.  Went up from $39.99 to $57.99 which I am very sorry to say is out of my price range.  It sucks because I LOVE this app and have been using it for many many years.  Oh well…off to find something less expensive….😞

### 2/5 — Should be free

*2026-08-26, version 6.26.32*

Went from owning to needing a subscription while they find new ways to make money off our data. Customers get asked for more input to feed profit margins. Tiring

### 3/5 — UPDATED: app can’t track you when you play it’s sounds to fall asleep

*2026-08-25, version 6.26.32*

2026 update: I’ve started using the in-app options for music and soundscapes to fall asleep to rather than my stereo. 

Unfortunately, it’s messing with the app’s ability to detect when I’ve fallen asleep and all the readings and data is now inaccurate. 

If the app is going to provide me with the ability to play music / sounds IN the app, then the app should have the ability to filter out its own sounds when analyzing the sounds from the environment. 

I have two weeks of garbage data because of this. So frustrating. 


//////

Best part of this app for me is seeing the record of when I go to sleep & wake up every day as well as the time in bed vs. Estimated time actually sleeping. 

Please stop changing the location of the various stats on the journal page with every new update. So frustrating to have to be regularly reorienting myself.

### 3/5 — Wish it worked for me

*2026-08-25, version 6.26.32*

Still remains a mystery to me how people use it to ‘analyse’ and improve their sleep.

### 3/5 — Best app ever

*2026-08-25, version 6.26.32*

Update: it used to be the best app ever. But since they’ve decided to make more money out of users it’s become annoying. All the pop ups disrupt smooth usage of the app. Then the new dynamic of upgrading to whatever the next level is after having a premium account, I tried it cause I wanted to hear the environmental noise. Which we used to hear in my premium account. And it was a farce. You can’t hear anything, it just provides amplitude lines which is useless. I still use it daily, the app is great, but why did you need to try to squeeze more money out of users? 

Old review: Honestly this is the best app I own. I feel it does a fantastic service to one's sleep process. The wake up sound is fantastic and I love tracking my sleep cycle over the past almost 20 years. Thank you sleep cycle! :-)

### 2/5 — Poor analysis

*2026-08-23, version 6.26.31*

The apps algorithm is a joke. I get the same level “high” whether I cough slightly four times a night or have bronchitis and literally cough all night long.

### 1/5 — Disappointing - Sane Bug After Years

*2026-08-23, version 6.26.31*

I used Sleep Cycle in the past and stopped using it because it had a serious alarm problem. I decided to download it again recently, assuming these bugs had finally been fixed.

Unfortunately, the exact same issue happened again.

I set my alarm for 7:30 AM, with the Smart Alarm window set to 7:00–7:30 AM, and selected my preferred alarm music. Around 4:00 AM, the app unexpectedly woke me up with a beeping sound instead. That is roughly three hours before my scheduled alarm and completely outside the Smart Alarm window.

When I checked the app afterward, the alarm was still showing 7:30 AM / 7:00–7:30 AM, but the sound was no longer what I had selected.

This is a sleep alarm app. If I can’t trust it to keep the time and alarm settings I selected, I can’t trust it to wake me up.

I came back because I thought these issues had been fixed. Unfortunately, I’m disappointed to find that I’m experiencing essentially the same problem I had years ago. I should not have to use a second alarm because I don’t know whether Sleep Cycle will actually follow the settings I chose.

Please fix the alarm reliability and stop changing/overriding user-selected alarm behavior.

### 1/5 — Works for 4 days

*2026-08-22, version 6.26.31*

On the 5th day, it just freezes whenever you go to the journal

### 1/5 — Can’t get it to open or work

*2026-08-22, version 6.26.31*

I get to the subscription page and click start free trial and nothing happens, it’s just frozen.

### 1/5 — Платно и очень дорого

*2026-08-20*

Ужасно, постоянно приходит уведомление, вам 50% скидка. Удалите мой аккаунт! Нельзя сделать из приложения, пишет напишите по такому то адресу. Тех. неисправность. Уже месяц не могу удалить аккаунт

### 1/5 — Do not do a free trial!!!!

*2026-08-29, version 6.26.32*

I did a free trial of this and decided it wasn’t for me. It was literally impossible to cancel. I wasted over 2 hours trying to cancel this the day before the free trial ended including multiple emails to Sleep Cycle. No response and they ran the charge anyway. Luckily my CC company flag it and I was able to decline the charge. Horrible experience!

### 1/5 — Rubbish

*2026-08-29, version 6.26.32*

I purchased lifetime access years ago. At some point, they switched to a subscription model, and suddenly features I used to have access to are no longer available. They claim I still have everything from when I originally paid, but that isn't what lifetime access means to a consumer. You buy an app to support the developers and expect to keep using new features as it improves. They are beyond greedy. I even have to pay extra to use my watch as a sleep tracker instead of my phone. The current state of this app is rubbish. I hope alternative apps steal their customers for good so they get what they deserve.

### 1/5 — Scam

*2026-08-28, version 6.26.32*

Complete scam job. Don’t bother. I don’t know who they’re linked to or who they buy your info from, but stay clear. I’ve never used the app, it wasn’t on my phone but I somehow caught a $69.99 charge to my bank account. Had to look it up to find out what this stupid app is (by the way, you can find way better versions of this garbage app for free). Of course Venmo doesn’t care that someone stole your money, they never do. Reached out to apple support they said the charge wasn’t made through them I had to contact the app people. I contacted the app people and explained that I didn’t use the app I hadn’t made the purchase, and I’m a single father of three and I can’t afford to lose that money. That charge cleaned me out. They got back to me once, basically it’s not their problem and they’re keeping my stolen money. I’m contacting BBB and anyone else that will listen. I guess as long as I can’t afford gas to get to work the rest of the week I’ve got all the time in the world to make things difficult for these thieves. I’d say don’t download the app, but apparently it doesn’t matter they’ll find some way to steal your money. If I could give zero stars I would. Shame on you sleep cycle.

### 1/5 — Bad

*2026-08-28, version 6.26.32*

I cant even listen to my sounds in my sleep since it makes me pay!!! Not fair at all

### 1/5 — Pessima experiencia

*2026-08-28*

Fiz a conta premium através do benefício do Wellhub, permiti tudo que tinha pra sincronização com o Apple Watch, mas ele não está monitorando nada automaticamente. Tudo permitido no Watch e no app. Não faz o menor sentido ter que fazer isso manualmente toda noite. Decepcionante!

### 1/5 — Never works

*2026-08-27, version 6.26.32*

This app will not load 98% of the time yet charges 100% of the time. It simply does not load.

### 1/5 — Erased my session, impossible to contact

*2026-08-26, version 6.26.32*

I woke up and needed to re record and it erased the first session I needed. This thing has always been a piece of garbage that barely works and offers no help or contact support.

### 1/5 — Not Happy.

*2026-08-25, version 6.26.32*

The sleep graph never displays how I slept. Nothing but a straight line. That is from the time I sleep till the time I am awake. Why, is there nothing but a since I’ve been using this a year‼️

### 1/5 — Fraud

*2026-08-24, version 6.26.32*

No way to cancel subscription, no way to request a refund. Payment was charged without any warning.

### 1/5 — 非常耗电，根本无法使用

*2026-08-23*

之前明明不怎么耗电，还不错的，但是更新后一晚耗电超40以上，早上起来手机都是没电的，怎么出门？根本没法用，只能换一个了

### 5/5 — Ryan Harding

*2026-08-28, version 6.26.32*

Because my dad said to me that I have to use is and my dad was right all along and before I have I couldn’t sleep and then Aidan told me some tips about using is app that is can allow to make you sleep and it got a sleep tracker that tracked when you’re awake and when your bedroom lights and it can track your dreams and track when you’re in a deep sleep

### 5/5 — Sr.

*2026-08-26*

Muito bom e divertido, excelente para orientar e disciplinar na rotina de cada dia.👏👏👏

### 5/5 — Muito bom

*2026-08-25*

Perfeito e me ajuda muito a controlar meus hábitos de sono

### 5/5 — Sleep Cycle

*2026-08-24, version 6.26.31*

I love it. I’ve used this for over two years. Great help for me getting to sleep.

### 5/5 — Sleep getting better

*2026-08-22, version 6.26.31*

Since I have been using the Sleep Cycle app I have found my sleep has improved significantly and I am now able to get to bed at a reasonable time and more importantly I get up at set time in the morning. It has taught me so much about my sleep. I have recommended Sleep Cycle to my clients/friends having difficulty with their sleep. It is amazing!

### 5/5 — Tracking

*2026-08-20, version 6.26.31*

Very helpful to be able to correlate what I do before bed with the quality of sleep I am getting

### 5/5 — Great app!

*2026-08-20, version 6.26.31*

I really like this app so I know how much sleep I’m getting and weirdly I like to hear me snore and sometimes it catches me sleep talking. So weird to hear yourself when you’re sleeping.

### 5/5 — Great but not free

*2026-08-18, version 6.26.31*

It’s been a great help with my sleep, I just wish it had a few more things included with the free version. Waking up slowly to the music is SO much better than the crazy fog horn of usual alarms.

### 5/5 — Ich habe 2 Sleep Cycle premium abos auf einmal und es wurde auch 2 x abgebucht. Wie kann es sein, da

*2026-08-14*

Ich habe 2 Sleep Cycle premium abos auf einmal !!! und es wurde auch 2 x abgebucht. Wie kann es sein, dass mir als premium abonnieren nochmal ein premium Abo vorgeschlagen wird? Habe versehentlich dtaufgeklickt und hatte auf einmal mit meinem Partner zusammen 3!!! Abos! Es gibt mittlerweile auch andere Programme und werde wahrscheinlich auch kündigen! Apropos ! Bin mit Unterbrechung auch ein langzeitbkunde!
