I use Coach.me (website and app) to track habits that I want to do every day. For me it's thing like weigh in, track calories, exercise, write journal, but you can add any habit you want. It keeps track of streaks, so for example you'll be motivated to do your habit today because you don't want to break your 20 day streak.
