Techniques

Eight techniques.
Every state of mind.

4 · 4 · 4 · 4
Box Breathing
Equal phases of inhale, hold, exhale, and hold. Balances the nervous system and creates a sense of calm control. Used by Navy SEALs and surgeons before high-pressure situations.
⚡ Focus · Stress · Before meetings
4 · 7 · 8
4-7-8 Breathing
The extended hold activates the parasympathetic nervous system. The long exhale stimulates the vagus nerve, signalling safety to the brain and dropping cortisol within minutes.
🌙 Sleep · Anxiety · Wind-down
5 · 2 · 7
Physiological Sigh
A double inhale re-inflates collapsed lung alveoli, maximising CO₂ clearance in a single breath. The fastest known way to downregulate the nervous system — developed at Stanford's Huberman Lab.
🔥 Acute stress · Panic · Quick reset
5 · 5
Coherent Breathing
Six breaths per minute maximises heart rate variability (HRV), optimising both cognitive performance and emotional regulation simultaneously. The foundation of biofeedback practices.
🧘 Meditation · HRV · Daily practice
2 · 2 · 4
Energising Breath
Short rapid cycles stimulate the sympathetic nervous system, raising alertness and body temperature within 60 seconds. The antidote to the mid-afternoon slump.
☀️ Energy · Alertness · Morning activation
4 · 2 · 8
Cyclic Sighing
A nose inhale followed by a short top-up breath, then a slow full exhale through the mouth. A softer variation of the physiological sigh — well tolerated by beginners and those with anxiety.
😮‍💨 Calm · Beginners · Anxiety relief
5 · 5 · 2
A52 Method
Five-second nasal cycles with a brief two-second post-exhale hold. The empty pause activates the diaphragm and builds CO₂ tolerance. Developed for sustained attention under pressure.
🎯 Focus · Attention · Performance
4 · 4 · 4 × 2
Alternate Nostril
Nadi Shodhana pranayama — each cycle alternates breath between left and right nostrils, balancing the sympathetic and parasympathetic nervous systems simultaneously. Studies show improved spatial memory and calm alertness.
🧘 Balance · Meditation · Pranayama
Features

Guidance that gets
out of your way

📊

Visual bar animation

Four animated bars rise and fall with your breath — ascending on inhale, stepping across on hold, descending on exhale. No counting needed.

🎵

Tonal audio cues

Ascending notes guide your inhale, a gentle tick marks each hold beat, descending notes ease your exhale. Works with eyes closed.

📳

Haptic-only silent mode

Phone in your pocket, screen off, total silence. Distinct vibration patterns guide each phase — ascending pulses for inhale, steady ticks for hold, descending for exhale. Works in meetings, commutes, anywhere.

⌚

Apple Watch ready

The haptic language is already built for Watch. A companion app brings screen-free sessions to your wrist — glance at the bar animation or feel the pattern without touching your phone.

📈

Before/after mood tracking

Rate how you feel before and after every session. See the evidence that it worked — your mood delta, session history, and consistency over time in one clean view.

🔒

Private by design

No account required. No health data transmitted. Everything stays on your device. No ads, no tracking, no data sold — ever.

All session data is stored locally on your iPhone using Apple's SwiftData framework. This includes:

This data never leaves your device. It is not transmitted to any server. It is not backed up to iCloud. Deleting the app permanently deletes all session data.

3. Data we do not collect

4. Subscription and payment data

BreathLead offers an optional premium subscription processed entirely through Apple's App Store. We never see or store your payment information. Subscription management is handled by RevenueCat, Inc., which processes subscription status on our behalf. RevenueCat receives an anonymised app-specific identifier to verify your subscription entitlement. No personally identifiable information is shared.

If the app crashes, anonymised crash data may be sent to help us identify and fix bugs. This data contains no personally identifiable information — only device type, iOS version, and the code location where the crash occurred.

6. Analytics

We collect minimal anonymised usage analytics to understand which breathing techniques are used most and where users encounter problems. This data is aggregated and cannot be linked to any individual user. No behavioural tracking or user profiling is performed.

7. Children

8. California residents (CCPA)

We do not sell personal information. California residents have the right to know what data we hold about them and to request deletion. Since we store no personal data on any server, there is nothing to disclose or delete beyond what is already on your device.

9. Changes to this policy

We may update this policy as the app evolves. Material changes will be noted with an updated date above. Continued use of the app after changes constitutes acceptance of the updated policy.
