The problem
Most habit trackers reduce progress to a bare number, and lock your data behind an account you can't export from.
The approach
Built an offline-first tracker where each habit's streak grows a small vine — seedling to tree at 365 days — backed by a GitHub-style heatmap, monthly calendar view, and both check-off and quantity-goal habit types with weekly targets. Everything lives in local storage with one-tap JSON export for backup, plus multi-language support.
The result
A habit tracker where the visual reward (a growing plant) makes the streak feel earned, not just counted.
