Show HN: My app for stopping BAD habits

I built an iOS app called HabitCrush to help me (and hopefully others) quit bad habits (like procrastination, porn, junk food, or over-eating..)

It is like an inverse habit tracker. The idea is simple: name the bad habit, and every day you say no to the bad habit you get the satisfaction of “crushing” it in app. As a Bonus, each day you succeed, you get a unique gemstone as a small symbol of progress. The gemstone is computed on the day timestamp so it is unique and never comes back.

Would love feedback especially on the approach and whether the daily gemstone mechanic feels useful or gimmicky.
