Recognizing that physical functions and lifestyle habits vary from person to person, analysis is tailored to each user's unique characteristics.
Daily analysis results serve as a "preventive guide" for protecting your and your family's health.
(Analysis results are not intended for medical diagnosis or treatment. Please use them as reference information for prevention and lifestyle habits.)
For analysis purposes, measurements such as weight, temperature, and blood pressure, diet and toileting information, exercise intensity and duration, and symptoms for each day are recorded and managed, allowing you to review them later.
While AI (artificial intelligence) is partially utilized in the analysis, it is carefully designed in conjunction with proprietary logic for peace of mind.
