Trello uses collaborative boards to simplify projects

Unless you're a personal productivity geek, investing time in a new tool can seem like a huge chore (and, in the short term, a guarantee of being less productive). But there are many who work in groups who swear by Trello (not to be confused with Twilio) , which organizes group projects into neat, easy-to-navigate columns that are easy to edit and which can hold images, data files and other essentials.

Yes, I know, I've been preaching the gospel of Slack recently, but while Slack is more for team communication and chatting, Trello excels more as a turbo-charged to-do list and project management app and it also works with Slack.

Last year Trello exceeded 10 million users and while it's not perfect (there was a brief outage reported on the same day this was written), it seems very handy whether you use the free or paid version on a computer or mobile device.
