YouTube Tracker is a free browser extension developed by Rakambda for the Chrome platform. As the name suggests, this extension allows users to track their time spent on YouTube. It offers two types of time tracking: the total time of opened videos and the time spent playing videos.

With YouTube Tracker, users can view their tracked times through a popup icon, which displays the information as text and in a chart format. This provides a visual representation of their YouTube usage. Additionally, users have the option to send their data to a server, allowing them to compare their YouTube habits with others.

Overall, YouTube Tracker is a useful tool for those who want to monitor and manage their time spent on YouTube. It provides valuable insights into YouTube usage and encourages users to be mindful of their online habits.
