I use taskwarrior (for tracking todo items) and timewarrior (for logging work and what I've done with those items). It integrates nicely in my current workflow (every time I spawn a new tmux window a todo list along with my current time tracking and my calendar for the rest of the day pop up), and it emails my personal address at 18:30 a list of what I've accomplished for the day and the highest priority tasks for the day tomorrow. I do like to live in the console. If you're not a console/cli junkie, this might not work for you.
