MIDATA serves as a data repository for its members and other participating members of the public. It is a non-profit cooperative facility that operates without offering financial incentives, similarly to blood donation services, for instance. The account holders are not paid for their intentional and voluntary «data donation». The revenue generated from the integration of their data into a scientific study is reinvested in the services offered on the platform and in a variety of smaller research projects. Start-ups, IT service providers and research groups can use the platform to offer mobile apps, such as health apps or apps for treating and monitoring patients with chronic illnesses. MIDATA is currently being used in a number of scientific health projects. In one particular project being conducted at University Hospital Zurich, for example, multiple sclerosis patients are being included in a study into the effect of treatments, which uses a tablet app to test their cognitive and motor skills. A further project, currently in development at ETH Zurich, will look at different training methods and the impact they have on muscle growth. More and more projects are being run that are directed at a wide section of the population and are of value to many – as is the case with the «Ally Science» project.
