## What is Hotmoon?

Hotmoon: Seek Within, Sleep Deep.

At Hotmoon, we believe restful sleep starts before bedtime. Whether it’s your breath, your mind, or your mood, true rest begins the moment you start letting go. That’s why we craft various sounds to slow your breath, calm your mind, and guide you gently into serenity.

For light sleepers, busy minds, new parents, and anyone who struggles to unwind—Hotmoon adapts to your needs, not the other way around.

Because sleep problems are personal.
And one sound doesn’t work for everyone.

Hotmoon gives you the freedom to explore, mix, and discover what truly helps you sleep better.

### 5/5 — Thanks Much !

*2026-07-11*

Great Product- Wife and I asleep much better.

**Developer response:** Thank you very much for your recognition. This will be the driving force for us to continue improving our product experience.If you need help, you can contact us by email at support@hotmoon.com.

### 1/5 — Is this a dating app??

*2026-01-05*

So this app needs my personal information just to… set an alarm? It also requires users to be 18+, which makes no sense for a basic utility. I’m not on parole, I just want to know what time it is, not a background check. An alarm clock should wake me up, not watch me sleep too. If my daily routine is part of the product, you might as well ask me to write an autobiography for you to publish too.

### 3/5 — Works Great for Awhile then doesn't

*2026-01-03*

Love the device when it's working.  When it acts up, the sound will turn off and back on—no clue how to fix it. I went for a year without using it. I plugged it back in recently; it worked great for about a week, but now the sound is stopping again. Please update the software again.

### 1/5 — Must be 18+ and agree to possible sale of data

*2025-12-02*

Just to set the time on my clock I need to use this app. I don’t understand why I need to let you sell my data just to use my clock. And why on do I need to be 18+ to use this app that is listed as Ages 4+ and also does not disclose that any personal information is collected?? Please fix the App Store listing

### 1/5 — App disconnects

*2025-09-03*

The app has to pair with the device each time the app is used. If I leave home and return, the app can’t find the device again until it pairs again.

**Developer response:** Thanks so much for sharing your feedback. Our device connects through Bluetooth, so the Hotmoon app needs to be in the same room to pair smoothly. If it's still giving you trouble, just drop us a note at support@hotmoon.com and our friendly after-sales team will gladly help you out.

### 3/5 — So close

*2025-08-30*

There are so many things that I like about this app, but the one issue I have overshadows all of them. Some sounds that are working perfectly will just suddenly begin to pause for a few moments. I have had almost 10 sounds do this now and they are unusable at this point. It will just suddenly stop making any sound before picking back up. It wakes me up every time. 

This isn’t a plug or connection issue, it is just the sounds themselves. It’s been going on for months with no fix. Very disappointing

**Developer response:** Thanks so much for your feedback. If you run into any issues with your device, please reach out to us at support@hotmoon.com. Our after-sales team will be happy to follow up and make sure everything gets taken care of.

### 4/5 — Almost Perfect!

*2025-04-17*

I use my Cocoon Pro to go to sleep every night—The two main issues I’m having is that my favorite sound: Deep White Noise would suddenly pause at random intervals and I would instantly wake up from the silence. The other sounds seem to work well though. Another thing is that I wish I could change to bluetooth mode from the app. Other than that I am happy

**Developer response:** Thank you very much for your suggestions. The Hotmoon product team attaches great importance to user experience feedback and will continue to optimize the product.

### 1/5 — Cuts out

*2025-04-04, version 4.3.2*

Had my cacoon pro since new years, it is now April and cuts out and turns back on multiple times and wakes me up. I absolutely despise this machine - just stick with a fan.

### 3/5 — Cuts out

*2025-03-24*

I’ve had this sound machine a few months. Was great but recently it started stopping every couple minutes then comes back on. Annoying and defeats the purpose of a sound machine. Please fix.

### 5/5 — Works Great

*2025-02-25*

Not really sure what all of the complaints are about because I’ve had zero issues with this app for controlling my sound machine. 

It works exactly as advertised, nothing more nothing less.
