build-a-bit is a minimal habit tracking tool designed to help users build new habits and break bad ones. Developed by alexander.athorne, this free Chrome extension replaces your new tab screen with a simple yet effective kanban board interface. Inspired by the principles outlined in the book "Atomic Habits" by James Clear, build-a-bit focuses on making habit tracking and reinforcement a part of your daily routine.

The core feature of build-a-bit is its kanban board layout, consisting of three columns: Not-Doing, In-Process, and Doing. Users create habit cards, specifying the habit, frequency, and periods-till-doing. By marking completed habits in the In-Process column, users progress towards moving habits into the Doing column. Unlike other complex habit-tracking tools, build-a-bit offers a straightforward approach without unnecessary features, making it a reliable choice for consistent habit-building.
