What you get
Built for exactly this — and nothing you don't need.
Six classical techniques
Nadi Shodhana, Bhastrika, Kapalabhati, Anulom Vilom, Bhramari, and Surya Bhedana: each with its proper ratio, count, and contraindications.
Session builder
Stack techniques with custom durations, reorder them, name the stack, and let auto-transitions handle the hand-offs.
Guided pacer
A full-screen breath circle synced to each phase, with synthesised audio cues and a light haptic tap on the inhale.
Honest HRV
Reads heart-rate variability and respiratory rate before and after a session, and writes Mindful Minutes to Apple Health.
Starter stacks & trends
Morning, Midday Reset, and Wind-down stacks, plus a 14-day local trend of your practice.

Up and running in under two minutes.

A note from the studio
“I practise pranayama and wanted a tool that respected it — correct ratios, no upsells, no streak guilt, and no data leaving the phone. BreathStack has no analytics and no network calls at all. It just helps you breathe.”
Questions
The honest answers.
What data does BreathStack collect?
None. It has no analytics, no crash reporting, and makes no network calls. Everything stays on your device.
Is it really a one-time purchase?
Yes — $19 once, forever. No subscription, no ads. The free tier lets you run one session a day; the unlock removes that limit.
How does the Apple Health integration work?
With your permission it reads your HRV and respiratory rate just before and after a session to show an honest delta, and writes Mindful Minutes. It reads and writes only what you allow.
Is this medical advice?
No. BreathStack is a wellness tool. Some techniques are intense — stop if you feel unwell, and consult a doctor if you have a heart or respiratory condition.
