Trello helps you stay organized and to get things done. The app lets you create boards for all the projects you're working on. It is a highly customizable digital bulletin board that you can use to set up anything from to do lists, tasks, notes and more.

You can work on these individually or add colleagues so they’re kept up-to-date with the tasks they’re undertaking. As well as this, you’re able to add to-do lists on boards, assign tasks, comment on items, upload files and videos, and attach files. It’s free to use, although you have the option to upgrade for added functionality.
