Habit tracking!

I'm doing this with Duolingo (the language learning app). It has you build up a "streak" of days when you do at least one lesson. Even though you don't really get anything for it, it's amazing how much it motivates me to actually open the app and get a lesson done, even when I don't really want to. My current streak is 176 days. You can "freeze" your streak for a couple of days if you forget/are unwell so I may have missed a day here and there, but my commonest reason for "missing" a lesson is that I complete it after midnight when it still feels like the day before to me.
