I forgot to mention mine:
Trello for daily tasks(mostly towards my professional evolvement, like do that course, or spend some time with you side project)
Calendar for what matters in terms of time(go to the doctor at 5pm)
I am tracking habbits with the Seinfield method(like eat an apple every afternoon, no excuses)
Sometimes I find it useful to note them down to a scrappy paper, just for the visual-kinesthetic part
