I wonder if some manual bookkeeping is necessary to develop a habit and give room for introspection/reflection? Currently, I use Wunderlist and I have weekly lists. At the end of the week there is the manual process: create list for the next week and move everything left from this week over. Then I quickly look through the done items of the week. I also have lists for long term and recurring items, but the process does not really work well. I forget them, they get outdated, etc.
