Box Breathing: Breathwork
Paced exercises, vagus nerve
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Breathe for two minutes, and the sky gets one star brighter.
A calm voice leads the rhythm, a slow pulse of vibration marks each phase. You can close your eyes. You can put the phone down entirely and follow the taps on your wrist.
Every finished practice lights a star. The stars gather into real constellations — Ursa Minor, Orion, Scorpius, Lyra. A missed week puts nothing out: the sky you have built stays yours.
RHYTHMS
• Box breathing — four equal parts, the one to start with
• 4-7-8 — a long exhale with a hold before it, closer to night
• Coherent breathing — five seconds in, five out, about six breaths a minute
• Extended exhale — four in, eight out, almost nothing to count
• Physiological sigh — a double inhale, then a long release
• Alternate nostril — the voice names the side, so your eyes can stay closed
• Lengthening exhale — an exhale that stretches from four seconds to ten
• Your own rhythm — four numbers, and a new constellation appears
A VOICE, IF YOU WANT ONE
Six voices in eight languages, from a quiet whisper to a steady low register. The voice says only what is needed: in, hold, out. If your own music is playing, it is lowered for the phrase and released at once — never stopped. And if you would rather have silence, one tap turns it off.
ON THE WRIST
The watch app is a full practice, not a remote. Vibration leads the phases, so the screen can go dark and the practice continues: your arm is down, you are breathing, the watch is counting. A practice done on the watch lights the same star — the sky is one for both.
ALSO INSIDE
• A daily reminder at a time you choose, scheduled by your iPhone alone
• Four background loops, from a low drone to sparse notes in silence
• A breath-hold stopwatch — a private mark to compare with yourself
• Eight interface languages, switchable inside the app
QUIET AROUND YOUR DATA
No account, no sign-up, no analytics, no advertising. Your practice history stays on your device and goes nowhere. The app goes online for one thing: to check whether the purchase is yours.
ONE PURCHASE
Four practices, a voice, a background loop and your own rhythms are free, with no limit on sessions. The full set opens with a single payment. No subscription, ever.
The sky remembers every practice. Even the one after which you forgot to open the app for a month.
Breathing practice is not medicine and does not replace a doctor. If you feel unwell, stop.
