Habit Tracker

A simple habit tracker built with Next.js, React, TypeScript, and SQLite.

The app is centered around a straightforward daily checklist: create habits, mark them complete, and keep a lightweight record of how things are going. It also includes a small insights view for monthly consistency, but the core idea is intentionally simple.
