We're excited to share a major milestone in respiratory health technology: the WellO2 MyBreath smart mouthpiece has been scientifically validated in a peer-reviewed study published in Medical Devices: Evidence and Research.
This independent validation supports what our users and internal testing have already shown: MyBreath provides accurate, reliable feedback that helps people monitor and improve their breathing performance. Now, it’s backed by published science.
Why Measuring Your Breathing Strength Matters
We breathe over 20,000 times a day – but how often do we think about the quality or strength of those breaths?
Unlike step count or heart rate, breathing strength is harder to quantify without specialized tools. That’s exactly what MyBreath offers: a smart respiratory device that gives you real-time, measurable data about your lungs.
By making the invisible visible, MyBreath helps users gain self-awareness of their breathing patterns, track their lung function over time, and make smarter decisions for their health – whether for recovery, performance, prevention, or general wellbeing.
What Is WellO2 MyBreath?
MyBreath is a smart mouthpiece that is used together with the WellO2 breathing trainer and connects to the WellO2 mobile app. It measures inspiratory and expiratory pressure, giving you clear metrics to monitor your breathing strength at home. It also measures your breathing capacity as well as airflow.
Whether you’re managing your breath for athletics, vocal performance, respiratory recovery, or simply maintaining good health, MyBreath helps you:
- Visualise trends in your breathing capacity
- Adjust your training in real time
- Stay motivated with measurable goals
It turns subjective sensations into actionable insights – making breathing exercises more effective and engaging.
