DiiG is a research and clinical app used by Dr. Venkat Bhat, MD and team of collaborators. It is used my members of the DiiG group to better understand and improve brain health. The app is customizable and can collect information about your health through real time surveys, brain games to check your thinking, Apple HealthKit data like step count and heart rate, as well as phone sensor data. If you are part of a DiiG research/clinical study or program, we invite you to download DiiG onto your phone after signing informed consent with staff from the DiiG team. For information on the privacy policy and terms and conditions of DiiG, please refer to the handouts provided by DiiG staff.
