Personal Tracker

Personal new-tab dashboard for Chrome to keep your todos right in front of you every time you open a tab.

Overview

A minimalist personal dashboard consolidating Todo (Kanban + calendar), Notes, Bookmarks, Pomodoro, and habit tracking on a single screen.

All data stored locally in the browser (localStorage), no backend required — set as default/new-tab page in Chrome.

Core idea: turn easily forgotten tasks into something that directly hits your eyes whenever you open a tab.

The problem to solve

I often forget todos, and typical apps require opening them. I wanted them to appear right in front of me without searching.

How we approached it

Built as a new-tab page: see todos instantly upon opening Chrome.
Consolidates productivity widgets (Kanban, calendar, Pomodoro, notes, bookmarks, habits) into a single screen.
Local-first with localStorage, no backend — lightweight, private, and simple to deploy.
Used AI (Fable 5) to assist with coding, while I focused on review and direction.

What the product does

Todo Kanban + Calendar

Backlog / Todo / Doing / Done board, with daily calendar view.

25-minute focus timer with alerts via Web Audio API.

Notes

Quick scratchpad for todos and reminders.

Bookmarks

Technical challenge

Problem

Enable instant use as new-tab, keep it private, and avoid setting up a backend.

Solution

Local-first: all data in localStorage; Notification API + Web Audio API for alerts, and CORS proxy for bookmark metadata — all running client-side.

Results

Setting as new-tab keeps todos visible every time a new tab is opened.
