Habit Streak Tracker

Create a visual habit tracking application that gamifies daily routine building through streak counting, progress visualization, and achievement systems. Users struggle to maintain consistent habits, and this tracker provides the motivation and accountability needed to build lasting positive routines.

What You'll Build:

Your application should allow users to define custom habits, check them off daily, and visualize their consistency through calendar heatmaps and streak counters. The system tracks current streaks, longest streaks, and provides motivational feedback to encourage continued engagement.

Key User Stories:

• As a user, I want to add custom habits like 'drink 8 glasses of water' or 'read for 30 minutes' with personalized names and descriptions
• As a user, I want to check off completed habits each day and see my current streak immediately update
• As a user, I want to view a calendar heatmap showing my consistency over the past year, similar to GitHub's contribution graph
• As a user, I want to earn achievement badges for milestones like '7-day streak', '30-day streak', or 'completed 100 total habits'
• As a user, I want to see statistics like completion percentage, average streak length, and best performing habits

Technical Implementation:

Design a data storage strategy for time-series information and implement visualization components for progress display. Consider goal-setting mechanisms, trend analysis, and data export functionality for user insights.
