tracker.pro is a Chrome add-on developed by levincent06 that aims to improve productivity by hiding suggested videos on YouTube and tracking the time spent on unproductive websites. With this add-on, users can remove YouTube home, trending, and library videos, as well as "Up Next" videos, preventing endless clicking from one video to the next.

The core features of tracker.pro include the ability to track daily time spent on YouTube, display a live time counter on the add-on's icon, and add or remove custom websites to be tracked. Additionally, users receive a notification every 60 minutes to remind them of the unproductive time they have spent each day. The add-on also allows users to view their tracked unproductive time for the past 365 days.

Developed by Vincent L. and designed by Jason L., tracker.pro provides a useful tool for individuals looking to reduce distractions and increase productivity while using YouTube and other websites. With its customizable features and tracking capabilities, it offers a simple yet effective solution for managing online time.
