Used this since I was in senior high school and never found any other app that was better than this. What I like the most is the compatibility on every device and the data that we can look on how productive we're in a day, month, and year format. Don't forget the achievement badge too.
I am still not sure whether having habits and pomodoros (I use Pomo for specific recurring activities) in the same app where todos are, however, TickTick got me, a seasoned productivity geek and a project manager, to a whole new level of control.
