The Habster app is designed to assist users in developing and maintaining healthier habits through a structured approach. It emphasizes the habit formation process by incorporating a 'habit loop' consisting of cues, routines, and rewards. Users can set personalized mantras as positive affirmations, visualize their goals with the Habit Wheel, and receive daily motivational insights through the Wisdom of the Day feature, which is accessible upon marking a habit as completed.

To facilitate habit formation, the app offers various features such as a calendar for tracking progress, a diary for reflecting on daily achievements, and customizable reminders to maintain motivation. Users can select between limited and lite modes to structure their habit-building journey over 21 to 28 days. With a focus on consistency and accountability, Habster aims to help users achieve meaningful and lasting changes in their daily lives.
