about.

this site started because I have ADHD and the existing focus tools all annoyed me in different ways. Pomofocus has no sound. Forest is paid and mobile-only. Brain.fm wants $70 a year for what is, fundamentally, brown noise. YouTube has ads in the middle of your work block.

so I built focuscave. one developer, one weekend, then a lot of small weekends after that. everything works in your browser. no signup. no ads while you're focusing. just the tools.

what's here

a Pomodoro timer with built-in brown, pink, and white noise.

an ambient sound mixer for layering rain, café, fire, and the rest.

guided breathing for the minute before you start.

a life-in-weeks visualizer for the moments you need perspective.

a quiz that recommends a focus technique based on your situation.

a countdown with shareable links like /countdown/25-minutes.

a BPM tapper for finding the tempo of what you're listening to.

a tab-title timer that lives in your browser tab, not the page.

personal stats — sessions, streaks, a heatmap. all in your browser.

what's not here

no accounts. no email collection. no tracking that follows you around the web. no AI in the product itself. session data lives in your browser. delete your localStorage and it's gone.

built for brains that drift. if it helps you, that's the whole thing.
