### 5/5 — Gerade gekauft

*2026-02-18*

Ich hatte Sleep Cycle bis heute genutzt, leider gab es dort immer mehr Einschränkungen und immer mehr Werbung trotz einmaliger Bezahlung.

Bei dieser App scheint alles zu stimmen, sogar die Restzeit bis zum Aufwecken wird angezeigt.

### 1/5 — Poor sleep

*2024-12-07, version 3.1*

I didn’t find the app st all helpful
I Ned sounds to get to sleep; waking is not a problem
Where is the science?

### 1/5 — Horrible

*2024-01-30*

App is just a Settings screen. Doesn’t do anything. Don’t buy

**Developer response:** Hmm.. the app is a fully functioning natural sound alarm clock with 750 sounds that also measures your sleep. Maybe you’re reviewing a different app? Try setting an alarm and look through the Sound Catalog to see 750 sounds.

### 3/5 — Malo

*2023-12-11, version 3.1*

No tiene sonidos para que te ayuden a relajar mientras te dormís, nunca registró sonido... no lo descarguen!!!

### 5/5 — Excellent

*2023-08-25*

This is a really good app, now I am able to get the amount of sleep I need with no guesswork on the matter and I feel much better for it, health has improved and so has my blood pressure, priceless.😀😀😀😀😀 I have had this app for a while now and I am still happy with how it works, but it can eat up storage space though it can be cleared.😀😀😀😀😀 Just to say there are lot of lovely sounds to wake up to, I recommend the Welsh Blackbird.

Can’t think why I have not used this in a while but now I have come back to it. I like waking to the sound of birds singing, by far more gentle than a ordinary alarm clock.

### 4/5 — Great

*2023-06-21*

This is great

### 3/5 — Etwas fehlt.

*2023-05-25*

Soweit gut, es fehlt aber unbedingt eine 2.oder sogar 3. Weckzeit.

### 4/5 — Great rain and stream sounds

*2023-05-10*

Glad I purchased

### 1/5 — Devi tenere sempre l’app aperta

*2022-10-09, version 3.0*

Molto scomoda, devi tenere sempre l’app aperta, impostarla ogni giorno, l’orario va a blocchi di 5 minuti, non è funzionale. Rischi di non capire quando è attiva, la sveglia funziona solo se attivi il monitoraggio sonno. Valutazione negativa.

### 5/5 — Как поставить будильник?

*2022-07-29*

Уважаемые разработчики! Подскажите как изменить время просыпания? Интерфейс не понятный… не интуитивный

**Developer response:** Чтобы поставить будильник, передвиньте белый шарик на край часов. Связывайтесь с нами через раздел "Вопросы и отзывы" в приложении. Мы будем рады помочь!
