    How accurate is the activity measured?

    Published on 2017-05-18

    The Philips health watch is a medical device.

    The key measurements and algorithms (e.g., heart rate, resting heart rate, energy expenditure) integrated in the Philips health watch go through clinical validation, meaning they are compared against a medical gold standard under various circumstances to confirm the accuracy of the measurements. Because of this, the data and accuracy can be used by a health care professional as part of a health assessment.

    To ensure the most consistent results from your health watch, follow these tips:

    • You have defined your personal wearing position in the app settings
    • The led lights are clean
    • The watch is tight but comfortably worn on the bare skin of the wrist
    • For some of the measurements data is collected during a week before the first accurate measurements can be shown

    The motion detector in your Philips health watch is very sensitive. You will have the best accuracy over a longer time period, like days or weeks, so be sure to wear the health watch consistently.
