QSCHECK App is built with a novel technology developed by QSTAG. It includes a patented algorithm which corrects errors that can occur depending on the lighting and smartphone models when scanning our QR Code printed urine strips. This technology, which has a 95% accuracy rate compared to hospital bench-top equipment, enables us to provide instant and reliable results to our users. In addition, QSCHECK App is a platform for users to review various diagnostic test results regularly when using our diverse self-administered products soon to be released. With such information, the QSCHECK App will provide personalized health-related information such as healthy food choices and exercise methods to maintain a healthy life.
