Breathwork

In for four, out for four. That's it. That's the app.

Try it right here

01The pacer

One circle, growing and shrinking with your breath.

02Patterns

Box, 4-7-8, coherent, and long-exhale — with honest cycle math.

03History

Sessions, minutes, and full breaths, kept privately.

Overview

Breathwork is deliberately the smallest app in the library: pick a pattern, pick a length, press Begin, and follow the circle. Phase cues are visual and text-only — no sounds, no accounts, no streak guilt. Sessions land in a private local history so consistency is visible without being gamified. The pacer respects reduced-motion settings, and the pattern definitions are one small array your agent can extend in minutes.

Make it yours in three steps

1

Download it

One click, one zip, the whole project. Free, MIT licensed, yours to keep.

Download Breathwork
2

Run it

Unzip it, then run this in the folder. It works immediately — no database, no accounts, no configuration.

$ npm install
$ npm run dev
3

Hand it to your coding agent

The download ships with CLAUDE.md, AGENTS.md, and Cursor rules, so your agent understands the project the moment it opens the folder.

$ cd breathwork
$ claude

Claude Code reads the included CLAUDE.md automatically — it already knows the project.

A good first prompt:

Give me a quick tour of this project, then help me make it mine.

Agent-ready information

Ships with CLAUDE.md, AGENTS.md, Cursor rules, and a full agent handbook — project map, safety rules, recipes, tests, and deploy notes.
