FAQ

  • Is PACER one-size-fits-all?
    Yes, PACER is designed as a one-size-fits-most product. While it fits the majority of users comfortably, if it doesn't suit your face shape, we offer a 100% refund guarantee — so you can try it risk-free.
  • Does the app sync data with other fitness apps?
    Not yet, but integration with fitness and health platforms is in development. We’re working to expand compatibility in upcoming updates.
  • Does PACER interfere with breathing?
    Not at all. PACER is designed for optimal airflow and comfort, providing better breathability than traditional lab-grade metabolic masks. It allows natural breathing, even during intense workouts.
  • Are there any parts that need to be replaced regularly?
    PACER is designed for regular use without the need for consumable replacements. However, we recommend checking for external contamination if the device is used over a long period.
  • Do I need to calibrate the sensors regularly?
    No manual calibration is required. PACER features an auto-calibration algorithm that ensures consistent and accurate measurements.
  • Which types of exercise can PACER analyze?
    PACER is optimized for running and cycling, but its 'Free Test' mode allows you to record breath data during various types of aerobic activity. Even outside these core sports, you can still track oxygen uptake, CO₂ output, and other key metrics.
  • Can I use PACER both indoors and outdoors?
    Yes, PACER is designed to work in both environments. Whether you're running outdoors or using a treadmill or indoor bike, it can collect accurate and reliable data.
  • Can PACER be shared among multiple users?
    Technically yes, but we do not recommend it. For hygiene and sensor reliability, we strongly advise individual use for the most accurate and safe results.
