A habit tracker is a tool used to monitor and record daily habits or behaviors. It can be a simple chart, a digital app, or a journal where individuals mark their progress. By visually tracking habits, users can identify patterns, stay motivated, and work towards personal goals, such as exercising regularly or drinking more water. Many people use habit trackers to build positive habits or break negative ones. They can be customized to fit individual needs, allowing users to focus on specific areas of improvement. Popular habit tracking apps include Habitica, Streaks, and Loop Habit Tracker.
