I use O365 Outlook/OneNote, etc at work and Gmail/Drive at home. They both offer free trial versions but you'll need to pay to set up a functional GTD system in either. I think todoist has more features but Nirvana is more orthodox GTD friendly. The two I keep coming back to are Nirvana and Todoist. Nirvana - great if you want to avoid a subscription, solid app, very stable, extremely compatible with GTD.Unfortunately, as I mentioned it doesn't work for my situation. MS todo - my favorite since it's free, built on the bones of Wunderlist, it's really a solid app.Other apps I've used with similar functionality for using two setups: A web app so I can access on a big screen while at work.Tons of Flexibility in setting up your lists.Email data entry - so i can forward items from either my work or personal email into my todoist inbox.Todoist has some features that make it useful for this: So I just use outlook tasks while at work and todoist for home stuff. MS To do would be perfect except that my employer's firewall prevents sync to mobile devices, which defeats the purpose for me. I use O365 for work and Todoist for home. I have to use two tools for work and home since in healthcare much of what I deal with is confidential information and cant cross paths. I think it would probably be ideal to have one tool, but it doesn't turn out that way for a lot of people. A common misconception upon the first read of GTD is that David is advocating for one tool. Trello integrates with Drive, Sheets, Slides, Chrome, Calendar, GMail, Inbox, and Google Apps.This is a common issue for a lot of people who are forced to use separate tools for work and personal. Trello boards create a shared space for teams to organize, collaborate, and share information to accomplish their business goals in a flexible and fun way.

Trusted by millions, Trello is a visual collaboration tool that gives teams a shared perspective on any project.
