It is made for the moment an agent starts working on a live site, and for a team and its agents working on the same one.
A SyncNow project is a website on a hosting reached by FTP, optionally with MySQL databases. The owner adds it, can invite managers to share the work, and every agent that works on it, from any PC of the team, uses the same tools and leaves its work in the same Activity.
Working alone benefits too: the project's Planning, Rules and history are kept on the SyncNow server, so a new PC or a new agent session starts from the same context. The app runs on Windows, and agents work on the PC where the app is open and signed in; see What runs on my PC and what runs on the SyncNow server?.
