Origin Story

Sonomo was born from a simple need: reliable, high-quality focus audio without the bloat.

I found existing solutions to be either too complex, filled with distracting features, or reliant on looping recordings that the brain eventually recognizes and rejects. I wanted a tool that disappeared into the background, allowing the user to enter a state of deep work or restful sleep.

By leveraging generative audio synthesis, Sonomo creates a soundscape that is mathematically perfect yet organic in its variation. It is designed to be the last noise app you will ever need; efficient, beautiful, and respectful of your time and privacy.

"Simplicity is the ultimate sophistication." – Leonardo da Vinci

Whether you use Sonomo to mask tinnitus, calm a restless mind, or maintain focus in a busy office, I hope it brings you the same peace it has brought me.
