What was the problem?
I like focus music in the background when I work. I used to put a track on YouTube, and the ads and recommendations kept pulling me away from my work. I also couldn’t see how much time I’d actually put in.
What was the idea?
A calm place for focus music: open it, choose a track, start it, and work. Every minute of music counts as focus time, so I can look back on my day.
What did I build?
I built it as a web app, because it was the fastest way to try the idea. It works on any computer, with nothing to install. It runs on Cloudflare Pages and works offline. My history stays in the browser, so there’s no account. I made the music with AI: one track on ElevenLabs, one on my own MacBook, both trimmed into seamless loops.
Stay Deep. When I focus: the browser loads the Stay Deep app and its audio loops from Cloudflare Pages once, then works offline. The session history is saved in the browser, with no account. Making the music, once: Reflect came from ElevenLabs, Grounded from Stable Audio running with MLX on my MacBook. Both were trimmed into seamless loops and shipped with the app.
What happened?
I used it for a while for my own work sessions. On September 20, 2026, my history showed 3h 20m that day and 30h 40m over the last seven days.
Then I realized it would make more sense as a Mac menu bar app, so I built that as well. That’s the one I use now. I’m also thinking about a mobile app, just for fun.
