Show HN: GitHub-style heatmap for habit tracking

I started coding this year. Seeing my GitHub commit chart green daily became addictive.

So I built a tool which could help me replicate the dopamine hit of filling up those squares for my other habits too.

Friends wanted to use it, so I added features: leaderboard, custom avatars. Now sharing it with HN.

No monetization plans yet. If it reaches 100+ users, might add more stats: productive days/hours, yearly habit wrapped, comparisons etc.

Would love to hear feedback from the community here. The green squares fueled my coding habit. Wondering if the red squares will do it for everything else!
