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!

Should be 5 stars..

Love this sound machine. I have not slept without a sound machine in years and this is by far the best!

Great quality speaker and sound options! Bonus features like using wirelessly, breath light and off line sounds.

4 stars instead of 5 because you can not easily listen to each sound individually. The “all sound” page creates a mix with each sound as you click through, then you must manually remove the previous sound to hear the next sound separately.
- hopefully an easy update that will make this the last new sound machine I ever shop for!

Thanks for your rating! You can tap the square picture of the sound you are playing, then you can stop it easily. Also we are developing what you expected.

Just doesn’t work properly

Very buggy trying to take the Omni on or offline. Will suddenly go offline for no reason and the app has to be restarted. Large pauses in sound before looping. App keeps turning on the light for the Omni randomly. Cannot use my phone for any other sound while the app is working. If you want background noise and to watch or listen to anything at all on your phone, do not try this. All around, didn’t do a single thing well.

Developer Response ,

We are sorry to hear you're not happy with our app. Please feel free to contact us via mail: After successful pairing, every time you turn on the device and Hotmoon App, they will automatically reconnect. If not, please tap "Home"-"Device" under the device list and wait around 5-10 seconds, the device list will be highlighted that the connection is successful. If still fails, please turn off the Bluetooth, Hotmoon App, and device, and try to connect again.
