Good concept, bad design and implementation

I usually use a noise-generating website, but am about to go on vacation with no internet access, so I needed an offline app.
This app has a lot of features, but a user interface that makes them very difficult to use. For example, it supports timers to start/stop noise or to sound an alarm, but instead of putting an easily-usabe button in the UI, it requires going through the menu and manage lists. There’s no quick way to see what timers are available, which are currently active, or add/remove them without manually digging into here. The list of available sounds is right on the main screen, why not a list of timers/alarms.
The list of availalbe sounds, mixes, etc., can be added too but I can’t seem to find a way to remove anything. If I experiment with sound mixtures and decide I don’t want some, too bad, they’re there forever.
I first installed this on my desktop and found the star “favorite” icon to be a the only way to create a custom list. You remove the star on one list, it gets taken off your favorite’s list. So that was one way to make a custom list even if you had to navigate through your ever-growing other lists. However, when I installed it on my MacBook the same day, the favorite list is prepopulated with things that are not even starred and while I can add things, I still can’t get rid of them.
The UI gives you the ability to mix different sounds that move around a 3D space, which seems unneccisary. Having the volume waiver in a pattern would be very useful, but that’s not an option in this app. Instead, you modify the “variance” and the source of the sound seems to move around where you’re sitting. Of course, if you’re not sitting at your computer this just distorts the sound randomly. If you’re playing this app while sleeping across the room, it’ll just distract you. The settings on this feature, especially the “speed” setting, sometimes will not change. I am currently running two sounds, ocean and brown noise, both with speeds at about 20%. The ocean is barely moving, it’s as if it’s less than 5%, but the brown noise is flying all over the place like it’s 100%. If I keep changing the settings over and over, they might eventually work, it’s just random. I did find a setting to disable 3D sound, but it doesn’t appear to work either.
