Diact, Dianovator’s cloud-based decision support for insulin-treated diabetes, brings novel insights and therapy adjustment recommendations to both clinics and patients. The web portal augments data visualization with analytic support to provide the care team with second opinions on how to best optimize long-term therapy decisions. For patients, the portal is available both as a web tool and as a mobile app. Patient and care provider meetings are facilitated by an integrated video meeting feature. We build our success on research and the user-perspective gained from personal experience with diabetes and glucose management.
