集中タイマー: A Pomodoro Timer and Block Website is a Chrome extension designed to improve the focus and productivity of individuals who work remotely or telecommute using their PCs. This extension helps users stay focused by combining a Pomodoro timer with a website blocker.

The main features of this extension include:

1) Pomodoro-style Timer: Users can set the timer for a duration between 1 minute and 60 minutes. The remaining time is displayed on the browser icon, and when the timer ends, an alert is shown without any sound.

2) Website Blocker: By default, popular websites like Twitter, Facebook, and Youtube are blocked. Users can also add an unlimited number of websites to the block list. Once a website is blocked, access to it will be restricted unless the block is turned off.

It is important to note that all these features are provided for free. This extension aims to enhance productivity during remote work or telecommuting by preventing distractions from social media and video platforms.

Please note that the extension uses Google Analytics to track the number of users and popular timer durations, but it does not collect or send any personally identifiable information.
