Sensor readings are provided by a compatible external Bluetooth device; OxyBoost does not measure heart rate or blood oxygen using the iPhone itself. The available readings and their accuracy depend on the connected sensor. Readings are displayed and saved as part of your training history and are not intended for diagnosis, treatment, medical decisions, or monitoring the safety of a breath hold.
Disclaimer: This app is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or another qualified health provider before starting any breathwork or apnea training and before making medical decisions. Do not disregard medical advice or delay in seeking it because of something you have read in this app.
