A Deep Breath is a breathing app that isn't a circle. The right page of a paperback lifts on your inhale, suspends on the hold, settles on the exhale. Every third breath turns a page — of Thoreau's Walden or Laozi's Tao Te Ching, embedded in the app from Project Gutenberg. Made quietly by sthreelabs.

A Deep Breath visualizes breathing as the page of a real paperback lifting and settling. Open the app; tap the cover; choose a pattern (4-4-4-4 box or 4-7-8 relaxation) and a session length (5, 10, 15, or 20 breaths). Every third breath turns a page of Thoreau's Walden or Laozi's Tao Te Ching — both embedded in the app from Project Gutenberg, picking up where you left off across iPhone, iPad, and Mac.
Most breathing apps animate a circle, dot, or expanding ball — abstractions of breath. A Deep Breath uses a metaphor more familiar than that: a paperback book opened on the screen, with the right page rising and falling in time with your breath.
Tap the closed cover. It opens. A small amber circle and the word inhale appear, and the right page begins to lift. Hold at the top. The page settles on the exhale. Every third breath, the corner curls and the page actually turns — revealing the next passage of the book you're breathing through.
The pattern is yours: 4-4-4-4 box breathing or 4-7-8 relaxation. The length is yours: 5, 10, 15, or 20 breaths. The book is yours: Walden by default for long-form essay reading, or the Tao Te Ching for short verses that reward repetition. Both are embedded in the app — nothing is downloaded — and each keeps its own bookmark.
For sessions where the text is too much, Quiet mode replaces it with abstract line patterns that read as prose from a distance. Same paperback. Same page-turn cadence. Just no words to chase.
It's part of the small paperback family of apps under the sthreelabs label, alongside Tallies (habit counter), A Spell of Work (focus timer), and One Line in Time (one-line journal).

A Deep Breath (and all sthreelabs marketing) uses the paperback design language. If you'd like to color-match in editorial graphics:
Typography: Crimson Pro (300–600 weights, italics) for body and headings. JetBrains Mono 400 for numerals and small caps.
Lines from the listing copy that are designed to drop cleanly into editorial.
