Stress Check is a biofeedback based app aimed to help users monitor their stress levels. There is one function, to calculate the user’s stress rating by placing their finger in front of the camera, and an option of including a contextual note to help the user notice stress patterns or triggers. Users are then encouraged to do an activity aimed to maintain or reduce stress levels, however these activities are not available in the app. The app does not require an external attachment.
