### 5/5 — The Best  Sleep Noise.  Period.

*2025-12-31, version 1.5.7*

I’ve searched the App Store.  This is the only one that provides both pure quality white, pink, brown and black noise with the ability to fine tune each noise to personal preference.  For tinnitus sufferers (like me) this is a revelation as I can adjust the precise frequency required to match and mask the unwanted internal noise.  

For any discriminating sleep noise enthusiast - this is the one to get.  It may look a bit technical at first, but you get used to it quickly.  And the developer is 100% responsive to any and all inquiries.

### 1/5 — No lifetime offer

*2025-08-17, version 1.4.6*

I was led to download this app by AppAdvice, where I was told there’s a lifetime offer. I don’t see any such promotion when I launch the app. Misleading.

(Response to that tone-deaf reply from developer: if there were a way to share a screenshot, I would have. I followed the instructions and all I found were two paid options. Nothing called “Lifetime” or anything similar. I’m not the only one saying so.)

(Response 2: I’m aware this offer was exclusive to AppAdvice, and I maintain what I said. It was not available even after following the steps outlined. It isn’t the first time I’ve tried accessing such deals, so I understand steps to redeem them might be specific. 2000+ users availed it, fair play to them and I’m happy for them, but using that as a means to annul my experience is ludicrous and, quite frankly, in utterly poor taste. Have a nice day.)

(Response 3: Keep parroting all you want, Mr Burgess, all AppAdvice said was “complete the onboarding and touch the top bar,” and that didn’t work. Go ahead, keep saying the same thing over and over if that makes you feel better (probably does because you seem to want to have the last word—sure, go for it), this is my last response—your crystal ball will tell you more about that I did or didn’t do.)

### 1/5 — Useless

*2025-08-15, version 1.4.5*

I paid for this app to play unlimited time but it still only play for 5 minutes. Terrible app.

### 5/5 — Great app

*2025-08-11, version 1.4.4*

This app is great. The support for it is awesome. Any suggestions or problems you have? You can email them and they will do their best to solve the problem that you are having it is a great app designed well works flawlessly

### 1/5 — App review

*2025-08-11, version 1.4.4*

The app requires a review before you use it the first time.

Developer responded that this is false. I just tried it again August 10 2025. The exact same thing happened, there is a page that asks for a review that cannot be bypassed, there is no skip option anywhere. This is 100% true on my IPad Pro running the latest version of iOS. The fact that the developer is claiming otherwise is bizarre. Reduced rating to 1 star.

### 2/5 — OK I guess

*2025-08-08, version 1.4.2*

Not free today as advertised!  Can't stand apps that are in portrait-mode only, as I need to turn my iPad Pro 12.9" sideways!  Plus, I don't use these white noise apps for sleep; I use them to drown out day noises.  I'll use my other excellent white noise app instead.
