Sanandco is an evolving entity. Starting as a certified designer and manufacturer of medical devices it has evolved into a lifestyle management website and now into a self improvement platform. We still support people with health related conditions, but also want to improve the fitness and well-being of the wider population and show people how to achieve goals in life through self improvement. We have a great device for measuring pulse transit time and look forward to developing applications for it's use with the help of our growing Vivrina community.
