StressScan is a technology that analyzes changes in heart rate interval to measure the level of mental and physical stress on a scale of 1 to 100. It works by analyzing the waveform of the heartbeat as measured at the fingertip, which allows it to analyze the balance of the autonomic nervous system and determine the stress level. This is based on the understanding that the autonomic nervous system can become disordered due to fatigue and stress from various causes. The technology used by StressScan is based on heart rate variability analysis, which is widely recognized in the field of heart rate analysis and autonomic nervous system research. It has been adopted by medical institutions, companies, and even the US military and NASA for stress care and health management.

StressScan is a reliable tool for measuring stress levels. It utilizes heart rate variability analysis technology, which is gaining recognition in the field. This technology has been adopted by various organizations, including the US military and NASA, for the treatment of post-traumatic stress disorder and astronaut training. The accuracy and effectiveness of StressScan make it a trustworthy option for measuring stress levels.

StressScan can be used in various scenarios, such as periodic checking of daily stress levels, checking the effects of meals and drinks on stress, and checking relaxation while traveling or at a favorite spot. It is compatible with camera- and flash-equipped smartphones, but not with devices that do not have these features. An internet connection is required to use StressScan, as it relies on external support for complex stress analysis. Overall, StressScan offers a versatile and convenient way to monitor and manage stress levels.
