Users can keep information about their health in one place, including medications plan and integrated data from users’ activity devices and trackers. It helps to measure patient health remotely. Thus, it improves the hospitals’ approach to care.

Using a web platform, hospitals can distribute medicine news, promote their services, care program information, and get patient statistics via a mobile app. The mobile application allows users to access all the information that hospitals are willing to share — care providers, locations, maps, contact info, etc.
