The reason that bad habits seem so hard to break is that your brain actually thinks the bad habits are pleasurable. It thinks it’s good to procrastinate, or smoke a cigarette, or eat a donut, or sleep in, or bite your nails. Your brain doesn't want to break the bad habit, even if you do.
Pavlok is a tool that breaks this dynamic, and creates a negative association between your mind and bad habits. It does that by using a buzz, beep, or shock when you do the bad habit. After just a few uses, your brain no longer wants to do those things.
It’s a serious tool who want fast, long term freedom from their worst habits.
