Honestly, for logging and tracking my daily business tasks, I use a plain old notebook where I write notes or draw sketches with a pen. It is the fastest and and most comprehensive solution. It accompanies me throughout the day and has more style than an electronic solution like a tablet. Of course searching is not easy but I can remember topics based on approximate dates, that works well for me.
For higher level "management" of longer-term and recurring tasks I also use taskwarrior.
