A software program intended to be installed on a non-medical smart device with an integrated camera to allow a layperson to: 1) analyse posture based on captured body images for the calculation of body angles and possible misalignments (e.g., Cobb angle); and 2) store image data for tracking changes over time (e.g., misalignment progression). It typically utilizes artificial intelligence (AI) techniques to provide postural data from the images. It does not require clinical consultation; it may additionally be used by a healthcare professional.
