is this application more convenient to use by the hospital or for individual?
Apps was made to make our life more convenient so I would rather say that both of them will benefit from Hearthy's platform.
Hospital with existing system can easily join the ecosystem of Hearthy without changing their IT provider, updating their software and instructing the whole organization for switching to the new software. Any healthcare providers and hospitals will decrease their financial burden by simply joining the Hearthy ecosystem.
Individual's using the Hearthy application for example patient can easily view and manage their medical records, use the chatbot that intended to help with psychological issues and also allows them to conduct a chat or video consultation when requested. On the other hand doctor or any health professionals could sell their services through the platform.
