Within the project we developed a mobile application for diabetes monitoring. The application supports the connection of a glucometer and various measurements of activity, and was part of a larger e-health solution. On the server side, the entire solution was based on FI-WARE (https://www.fiware.org/). The DeSA application has been developed in accordance with European and Norwegian legislation. The entire Diabetes Sharing System system, which connects the patient and doctor, thus complies with all the regulations and good practices regarding the storage and processing of medical data. The application was tested in a hospital test at a clinic in Troms in Norway, and is also available in the Apple App store.
