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. Download Hotmoon today and build your perfect night.

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

Can’t change modes from app. Repetitive sounds

There needs to be an option to change from Bluetooth speaker mode to cocoon mode from the app. What’s the point of an app if I still need to get up to go to the machine? Also, I found myself frustrated with sounds that had so much potential but we’re just way too repetitive and fake as a result. Specific examples are the thunder, cat purring, birds chirping, waves, etc.. each sound was back to back to back noise with no room to enjoy the first time it played. I like to hear the sound of the waves pulling back after they crash, but that sound was completely overridden by another wave coming in. It was so unnatural, as waves aren’t that repetitive in reality. Instead of being peaceful, it made the noises… noisy. And annoying. There needs to be 1 or two seconds before the sound repeats

Needs some improvements to the app

There needs to be an update to the schedule feature that will allow you to schedule your created favorites from the cloud options instead of just the ones on the machine. There is a timer setting but mine never runs the full hours without it stopping and having to turn the sound back on. I keep the machine plugged in at all times on a bedside table. Also, a wall adapter plug should be included with the purchase of the product. There may already be multiple schedule settings allowed but if not, that should also be an option. You should also be able to edit your favorites rather than having to delete the entire thing and start over. The sound machine otherwise is fantastic and the options are endless with the use of the app!

Almost Perfect!

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
