Decentralized HealthCare dApp

The other day i ran into this app named Patientory. To my surprise, i found out that it’s based on blockchain. I made some research about it and apparently, the project has been active and improving since 2015. Made me wonder why such projects that actually utilize the technology are not in the mainstream media. Users will have full control over their health data and it will be secured. This data of course is transferred privately when needed. I think this has the potential to advance medical research. We all know that since covid hit.
