Quitzilla

This app helps with relapse prevention and it can use for any bad habit including substance use. What makes this app especially unique is its habit-building feature. Quitzilla asks you about addictions and bad habits that you want to change, and it supports you in changing them. It helps you stay motivated about your “why” of recovery, and it rewards you for progress made toward new habits.
