OpenBreath

A breathing app for coherence practice: you set how long to breathe in, hold, breathe out and hold, and follow a sphere that opens and closes with the breath.

Nothing is asked of you first. There is no account, no sign-in and no network, no tracking — the app makes no connection of any kind, so your practice log is on your phone and nowhere else.

THE BREATH
• Presets for the usual patterns — coherence 5.5, 4-6, 4-7-8, box 4 — and any timing of your own.
• A sphere that opens as you breathe in and closes as you breathe out, as a cloud of points, bubbles, stars or a glow, in a colour you pick.
• Sound per phase: waves that rise and fall with the breath, a soundwave whose overtones gather and dissolve, a marker at each turn — singing bowl, bell or metronome tick — an mp3 of your own, or silence. The bowl and the tick are pitched by the turn they mark, so going into a breath in does not sound like going out.
• A singing bowl when the session ends, so you can sit with your eyes shut and not wonder whether it is over.
• Optional vibration at each phase change.
• Optional flashlight that brightens as you breathe in and fades as you breathe out — the breath to follow with your eyes closed.
• Optional silencing of notifications for the length of a sitting, put back exactly as it was afterwards.
• Time left, a dot per breath and a breath count, each hideable for a barer screen.

WHAT IT REMEMBERS
• Every sitting, day by day, with the pattern you breathed and the breaths you finished. The ones you cut short count too.
• Goals, as many as you like: one sitting a day, a hundred breaths a day, an hour a week. They are counted from the log, so a goal set today already credits the practice behind it.
• Streaks, totals and milestones at 3 days, a week, a month, 100 days, half a year and a year — each said once, quietly.
• Reminders, as many as you like, each with its own name and time: daily, on the days you pick, weekly or in alternate weeks. Either a quiet notification or an alarm that rings until you dismiss it. One can be set to arrive only when the day's goal is still undone.
• A backup of the lot — log, presets, goals and reminders — written to one file you keep and read back on any phone. Sittings merge rather than overwrite, so importing an old backup onto a phone you have kept practising on keeps both sets. The log can only grow.
