## Most critical reviews (10 lowest-rated)

### 2/5 — Marketing suggestion

*2024-12-15*

The free version should have a sound that everybody would like and that are simple, such as night and simple rain. You should also have more rain, like rain on tin roof and rain in forest, etc.

### 3/5 — Great Sounds

*2021-02-26*

Sounds are great...could be improve with more selections.

### 3/5 — It's nice but...

*2021-01-24*

The sounds are great. However, you do hear the repeating. Usually, apps like these for sleeping should have a subtle degraded effect to the sound when it does repeat. Otherwise, in my case, I was able to hear the repetition and it wasn't verycalming. IF you could improve the degrading effect on the repeating sounds, your app would be a hit!

### 4/5 — Nice Background Noise

*2021-05-19*

Nice free content, but much more available with payment.  The slection is decent, but I would have been much happier if there were more options available for free.

### 4/5 — Relaxing...

*2021-03-13*

If you want relaxing sounds or white noise in the background, this app does the trick!  Would be great if they came out with visual to go with the audio.
