Frequently asked questions

About the Product

What is SpiroFit and how does it work?

SpiroFit is a portable metabolic and VO₂ max analyzer that assesses cardiorespiratory fitness via breath analysis. It employs medical-grade sensor technology to measure real-time oxygen consumption (VO₂) and carbon dioxide output (VCO₂) during various protocols, including a resting test, a short step or ramp protocol, or a user-created protocol design. This analysis of gas exchange during inhalation and exhalation provides insights into aerobic capacity, ventilatory thresholds, and metabolic function, all without the need for external calibration.

What kind of health data does it measure?

SpiroFit measures a range of key respiratory and performance-related parameters, including:

  • VO₂max (Maximal Oxygen Uptake) — a core indicator of cardiovascular fitness and endurance
  • Ventilatory thresholds (VT1, VT2) — used to determine training zones and aerobic/anaerobic balance
  • Breathing frequency and tidal volume — insights into respiratory efficiency
  • Heart rate during testing — to assess exertion and recovery
  • Metabolic data — such as energy expenditure and fat vs. carbohydrate usage
  • Spirometry parameters — including FVC (Forced Vital Capacity) and FEV1 (Forced Expiratory Volume)

All data is collected using a portable device and displayed in real time through the connected mobile app and cloud dashboard, enabling detailed analysis and tracking over time.

Is SpiroFit a medical device or a fitness gadget?

SpiroFit offers laboratory-grade respiratory analytics, bridging the gap between clinical precision and wearable convenience. While not an officially registered medical device, its sensor technology, innovation, and engineering provide validated accuracy that allow it to provide clinical-grade results for fitness, clinical rehab, and professional applications. It’s more than a consumer gadget; it brings advanced respiratory analytics into the field.

Can it replace lab-based respiratory testing?

Yes. SpiroFit has been shown to provide comparable results to lab-grade analyzers, with the added benefits of portability, automatic calibration, and ease of use. It leverages high-performance heat transfer sensors and ventilatory threshold detection to deliver reliable VO₂ and gas exchange data without needing large lab setups.

Use Cases

Who can benefit from using SpiroFit?

Athletes aiming to improve endurance, optimize training zones, and monitor progress.

Clinicians needing non-invasive tools for cardiac or pulmonary assessment.

Trainers and coaches delivering personalized fitness protocols Health-conscious individuals tracking fitness or metabolic health over time.

Occupational performance evaluators in law enforcement, firefighting, and military contexts

Is it suitable for professional athletes?

Absolutely. SpiroFit delivers high-accuracy, granular data like VT1/VT2, VO₂ max, and substrate utilization. These metrics are essential for programming advanced heart rate zone training, evaluating overtraining risk, and peaking for competition

Can it be used in clinical or rehabilitation settings?

Yes. Even when classified as a non-medical device, SpiroFit supports submaximal VO₂ testing, making it ideal for patients in cardiac, pulmonary, or musculoskeletal rehabilitation. It allows clinicians to monitor progress safely over time, without pushing patients to maximum effort.

Does it support remote health monitoring?

Yes. SpiroFit connects via app and cloud-based software to allow real-time data upload and remote review by healthcare professionals or coaches. This enables longitudinal tracking and decentralized diagnostics in both clinical and fitness settings.

How to Use

How do I perform a test with SpiroFit?

Simply connect the SpiroFit to the app, don the mask and headgear, and begin the protocol of your choosing. The app will walk you through a step or ramp test. The device automatically calibrates and analyzes your breath data in real time. Testing results and reporting are viewed from within the cloud-based platform at no additional cost to you.

Do I need a smartphone or app to use it?

Yes. The SpiroFit system requires a smartphone or tablet and the companion app for operation, data collection, visualization, and personalized interpretation. While the app is currently supported on iOS, it will be released on Android in the future as well.

Is the test painful or physically demanding?

A standard test typically lasts 10 to 20 minutes, depending on the protocol and user fitness level. Including setup and cooldown, the entire process usually takes around 25 minutes.

Can I use it without medical supervision?

Yes. SpiroFit is designed for safe, unsupervised use. While maximal effort tests may not be advisable for individuals with health risks, the submaximal protocol allows most users to test safely and independently. Always consult a healthcare provider if unsure.
