Habitbull is great. I love how customizable it is for making different types of habits. Tracking my current streak is great for motivating me to keep on going. And even if I break my streak, I love that it shows my "best score" so I have a new goal to reach. The only thing I would suggest is having a "user suggestions" button in the settings. I have emailed about a new type of habit a couple times and have never heard anything back. User feedback is always good for making a great app even better
