Trello https://trello.com/ --> used this one for private coding projects or keeping track of bigger projects like renovations and such with a longer timespan and multiple stages.
As a visual person I do enjoy the look and feel, dragging around stuff, keeping track of the stages a certain work item might be in, adding updates/pictures etc. to the different items, adding colors and labels etc. ... a little bit cumbersome to use this in addition to sth else though.
