Evaluating the Accuracy of a Web-Based Application - Vital Sign Measurement Platform Description This single-arm cohort, open-label, and multi-center study is designed to evaluate the accuracy of a web-based application designed for measurements of vital signs including pulse rate (PR). It is hypothesized that the accuracy of the App is non-inferior to the accuracy of an FDA-cleared/approved vital sign monitoring device (reference device).

• Condition that does not allow the subject to remain still for 60 seconds at a time
• Subjects with cardiac arrhythmia
• Any known medical condition which may result in an inaccurate measurement using the reference device
• Subjects with the inability to complete an ECG.

The study will recruit subjects from clinics and hospitals and the general public. Enrollment of 85 subjects with an age range of 22-85 years of age with a wide range of skin tone categorization per the Fitzpatrick Scale ranging from 1-6.
