The free version is incredible. I dont use it yet with teams so cant rate that. As a "personal assistant," though, its better than all the other to-do-list tools Ive tried paid or free. Its very easy to reschedule tasks; the activity log is a useful feature; its easy to link emails or Google files to an item (card). One feature other tools use thats missing in Trello is a calendar view. However, with Power Up and a Trello calendar someone else developed, I can still use a calendar approach when I need it.
