It is neither Direct App nor is it distributed app. dApps stands for Decentralized applications (dApps), which are the applications that run on a Peer-to-peer network of computers rather than a single computer. dApps, have existed since the advent of P2P networks.
They are a type of software program designed to exist on the Internet in a way that is not controlled by any single entity.
Steemhunt, Actifit and Musing are some of the common examples of dApps built on the steem blockchain
You mean the meaning? It's Decentralized Application.
Basically, they are all applications/interfaces that are developed and run on the basis of the blockchain, such as musing and steemhunt that run on steem blockchain.
It is Decentralized Appication my friend and musing is a perfect example dApp built on the top of steem blockchain.
Steemhunt dtube actifit are the other examples of dApp on steem blockchain.
