hApps are decentralized applications (dApps) that are built on the Holochain blockchain platform. Holochain is an open-source, completely distributed network that allows anyone to create hApps. Many hApps are created to assist users in better managing their personal data by incorporating strict privacy and security measures. hApps include Elemental Chat (a secure P2P messaging hApp) and HoloVault (an integrated dashboard that allows users to manage how their data is used).
