I've been using Loop #Habit Tracker for #Android for a while now and I really like it.
Best features:
* isn't a jerk when you don't do your habit - the "habit strength" graph declines slowly instead of "lol back to zero, loser"
* flexible habits - daily, weekly, n times in a week, etc
* nice charts and graphs to visualize your progress
* open source / #FOSS
