Your Provider Has Recommended Precise Breath

Precise Breath finds the specific breathing pace that produces the strongest response in your cardiovascular system — your resonant frequency — using a chest strap heart rate sensor, and guides your daily practice.

What the Research Shows

Stress & Anxiety — A meta-analysis of 24 studies found that HRV biofeedback using resonant frequency breathing was associated with significant reductions in self-reported stress and anxiety (Goessl et al., 2017).
Blood Pressure — Controlled studies have associated resonant frequency breathing with reductions in blood pressure and improved baroreflex sensitivity (Steffen et al., 2017).
Autonomic Balance — Regular practice has been associated with strengthened autonomic regulation and improved heart rate variability over time (Lehrer & Gevirtz, 2014).

These findings describe published research on resonant frequency breathing as a practice. Precise Breath is a wellness tool — not a medical device. Individual results may vary.

Getting Started

Get a Chest Strap Sensor
You will need a Bluetooth chest strap heart rate monitor. The Polar H10 (~$100) is recommended for its research-validated accuracy. The Garmin HRM Dual also works. Wrist sensors and smartwatches are not supported.
Download Precise Breath
Available on Google Play (Android) and the App Store (iOS). A one-time Premium unlock ($14.99) enables the HRV analysis modes your provider recommends.
Run Your First Calibration
The Calibrate session (~14 minutes) tests 5 breathing rates to find your starting point. Turn on Do Not Disturb, wet the chest strap electrodes, and sit comfortably.
Practice Daily
Use Resonate mode for 15–20 minutes each day at your identified rate. Use Explore mode periodically to refine your frequency over time.
