2017 - Atlassian acquired Trello. Todoist should better react

Atlassian has acquired project management service Trello for $425 million. Just like with many of Atlassian’s other acquisitions, the company plans to keep both the Trello service and brand alive and current users shouldn’t see any immediate changes. With Trello, Atlassian is acquiring one of the fastest growing project management services. It now has about 19 million users. Trello brings more productivity to individual and team projects. It shows all of the projects from the entire team in a single glance. Assigning projects is easy, just put them in the assigned person’s or team’s list and when completed drag it to the completed list. Each “card” or task can be commented on and links can be added. Trello works across multiple devices and uploads files from Dropbox or Google Drive.

2016 - Todoist adds new collaboration features to catch up with Trello

Task management service Todoist is going to completely overhaul its collaboration features so that Todoist Business version becomes a full-fledged task management service for enterprise users. From now all team members can see an activity log so that you can see your newly assigned tasks, new comments and more. It’s a bit more powerful than that as you can filter by dates, person, project and action. Think about it as a sort of feed for everything that’s happening across all your projects. Besides, you can now attach notes to a specific project. This could be useful if you want to write notes that are relevant across the entire projects as task comments will inevitably disappear once a task is marked as completed. And finally, the quick add feature is getting a revised user interface. This change will benefit all Todoist users and not just team members.
