Bullet Journal

A beautiful year-at-a-glance habit tracker. Each day is a square, each habit is a color — like painting your year.

Bullet Journal turns your new tab page into a living year-at-a-glance habit tracker — like a GitHub contribution graph, but painted with your daily habits. ── HOW IT WORKS ── Each day of the year is a small block on the grid. Every block is divided into segments — one per habit you track. At the end of the day, open the popup, tick off your habits, and watch your grid grow. By year's end, your grid is a piece of art built from 365 days of small wins. ── FEATURES ── 📅 Year / Month / Week views Switch between a full 12-month calendar, a focused single-month view, and a detailed week view. Use the ← → arrows to navigate back through previous years, months, and weeks. ✅ Up to 4 habits Track between 1 and 4 habits simultaneously. Each habit gets its own colour and its own segment of the day block. 🎨 Full colour customisation Pick any colour from the full spectrum for each habit. Choose from earthy presets or enter a hex code directly. 🔷 Block shape: Square or Circle Prefer circular day dots? Toggle between square and circle blocks in Settings. ✂️ Three split styles Choose how your day blocks are divided when tracking multiple habits: • Straight — vertical halves, centre wedges, or 2×2 quadrants • Diagonal — \ triangle cuts, parallel diagonal bands, or an X from centre • Horizontal — stacked top/bottom halves or equal horizontal bands 📊 Habit statistics At the bottom of every view, see how many days you tracked each habit in the current period — with a colour-coded progress bar. 🖼️ Custom backgrounds Choose from warm gradient presets (Paper, Sand, Mist, Sage, Dusk, Plum), solid colours, or dial in a custom dim & blur overlay. 🔒 100% local, 100% private All data is stored in your browser using chrome.storage.local.
