Track Your Progress. Maximise Your Potential. All from Your Wrist.

We get it—you’re not looking for another app cluttering your phone or a complicated system to keep up with. That’s why X-Lung keeps it simple, powerful, and effective. Our magnetic breathing device helps you improve performance with results you can see, feel, and now—track. By using your existing smartwatch, you can measure real improvements in endurance, stamina, and wellness without adding any extra gadgets to your routine.

No gimmicks. No guesswork. Just results.

Here’s how your smartwatch can help you see the impact of X-Lung in action.


1. Heart Rate & Heart Rate Variability (HRV)

  • What it Measures: Heart rate and the variation between heartbeats (HRV).
  • Why it Matters: HRV reflects how well your body handles stress and recovers. A higher HRV typically means better recovery, while lower HRV can indicate fatigue or stress.
  • What to Track: Resting heart rate, HRV trends, stress levels.

2. Breathing Patterns

  • Key Metrics: Breaths per minute, breath-hold time, inhalation/exhalation balance.
  • Why it Matters: Monitoring breathing efficiency helps track lung performance and endurance improvements.
  • How to Track: Use built-in breathing apps (like Apple Breathe) or third-party wellness apps.

3. Sleep Quality Tracking

  • What it Measures: Sleep stages, disruptions, and sleep duration.
  • Why it Matters: Quality sleep supports recovery and overall wellness, especially when building stamina and endurance.
  • How to Track: Use your smartwatch’s sleep-tracking features and compare sleep trends before and after using X-Lung.

4. Oxygen Saturation (SpO2 )

  • What it Measures: Blood oxygen levels during rest and activity.
  • Why it Matters: Oxygen saturation provides critical insights into cardiovascular and respiratory health 
  • What to track: SpO2 levels before, during or after activity especially in high altitude training or endurance sports 

5. Activity & Recovery Tracking

  • Key Metrics: Steps, calories burned, recovery time post-workout.
  • Why it Matters: Faster recovery times and increased activity levels often correlate with improved fitness and lung capacity.
  • What to Track: Monitor how quickly your heart rate and breathing return to baseline after workouts.

You don’t need complicated tools to measure your progress. With X-Lung and the smartwatch you already own, tracking your growth has never been easier. See the results. Feel the difference. Own your performance.
