### 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.

### 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!

### 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.

### 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.

### 2/5 — Can’t set up recurring alarms.

*2026-08-18, version 6.26.31*

Good app. Annoying how we have to set the alarm manually before bed. If this feature is added I’d make my review 5 stars.

### 1/5 — Péssimo

*2026-08-18*

Primeiro que eu não entendo pq um app gratuito tem todas as funções pagas, então colocasse pago desde o início, não tem nada gratuito só as horas de sono, mas isso é óbvio que já sei as horas que dormi mas a análise do sono, áudio e afins é tudo pago, simplesmente horrível, já desinstalei

### 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.
