If you're a fan of the Personal Kanban productivity method, you're probably familiar with how helpful it can be to keep your focus strictly on the to-dos you have right in front of you, without the distractions of long-term projects or less important items on your list. KanbanFlow is a free web app that, as the name implies, fits right in, and even includes a built-in Pomodoro timer to help you stay on task.
KanbanFlow is completely free to use, and once you've signed up the tutorial will walk you through the process of creating tasks, moving them across your boards, flagging your to-dos with colours, adding and managing subtasks, and even setting up the built-in Pomodoro timer to work with the to-dos you've added. Adding items and managing them is super-easy, and you can set a timer for any to-do on your boards, including subtasks. If you don't want to cram all of your to-dos onto the same board, you can create as many boards as you want to organise all of your activities.
Finally, if you work with other people, you can invite them to the service to work with you, and you'll be notified when they update your boards. KanbanFlow is currently in beta, but it's pretty polished and remarkably fast. Even if you're not specifically searching for a Personal Kanban-style to-do manager, KanbanFlow is worth a look.
