flow is a lean project management application based on kanban.
The first time you run flow, you will see an empty kanban board with four columns: Backlog, To-do, In Progress, and Done. These columns represent the phases each task will go through, and you can have as many columns as you need.

All new tasks are placed in the backlog, and stay there until you move them to the next phase.
The numbers next to column titles are Work In Progress (WIP) limits. A column cannot hold more tasks than the limit allows. With WIP limits, tasks get completed fast and you do not end up with a lot of half-finished tasks.
It is a common occurrence that an otherwise finished task can get stuck in the queue because it needs input from another department or approval from the management. WIP limits can make it crystal clear where the bottlenecks are in your workflow.
flow supports keyboard shortcuts. Most actions are only a few keystrokes away. You can even hide the toolbars entirely to gain more screen space.
Project managers need to be on top of things all the time. There is no more need to go back and forth between projects. flow shows you the current state of all your active projects on the same page.
Every project is different. You may need more columns than the standard "To-do" and "In-progress", or want to define different task types.
Filter tasks by type, user or keyword, and see the results instantly.
Search for anything including tasks and comments.
Unless you plan to use flow for personal kanban, you would want to invite your team(s) to flow.
If you have multiple teams, you can create a group for each team. A user can be a member of multiple groups, too.
A group can have different permissions for each project. There are four types of permissions:
| View: | View the project's board, metrics, and task details |
| Create: | Add, rename, and delete tasks |
| Work: | Move, mark, assign, and change the type of tasks |
| Comment: | Post comments to tasks |
In flow, there are three built-in groups: guests, members, and administrators. Guests can only view projects (or not). Other permissions do not apply. Members is the default group all new users join when they accept your invite.
You can track your progress by looking at your project metrics:
You can generate custom reports by using one or more of the following criteria:
flow takes hourly snapshots of your projects as you work on them. When you click a day on the calendar, you can see the state of your project on that day. Days with no activity are grayed out.
When viewing a snapshot, you will see hours under the calendar showing that changes were made on those hours. You can click the hours to see how your project looked like at each hour.
When viewing a snapshot, you cannot make any changes to your board like adding or moving tasks. However, you can recover a deleted task by viewing that task's details and clicking the Undelete icon on the task's page.
flow even replays the changes between snapshots. You can rewind or fast forward to any date.
