Using this thing you can tell it's a labor of love. Best finding yet on product hunt. I suffer from ADHD and this is the most amazing noise generator I found (and I've tried many of them). Truly wonderful. I wish this thing will soon exist in an macOS app so we can use it offline. Thank you Lee for your skills, taste, and to be kind enough to share this with the community.
We also have a white noise machine. It’s good, but it lacks in the moment mood control. You just get 5 different frequencies.
The point of Midlife Engineering is to be able to engineer the sound to your current mood in any given situation ☺️
