Overview
Product summary
Review the store description, core capabilities, and common use cases.
Do you ever find yourself wondering how many minutes remain before lunch? Or how many minutes you have until class begins? After installing this extension, you can easily and quickly open an interactive countdown timer that shows this information and more. This extension accompanies Period Countdown (web application located at periods.io). The website and extension interact seamlessly — thus, when you change a preference on the full website (like a period name or theme), the changes will immediately propagate to the extension.
Disclaimer: This extension and its website (periods.io) are not officially endorsed or affiliated with any high school. Thus, we cannot guarantee the accuracy of our applications.

Loved it until the extension stopped working
The website works fine, but the extension has stopped working. Tried reinstalling, did not fix the issue. Icon is just greyed out.

Exceptional coding and interface, love to spend the last minutes of class staring at this chrome extension. Good job Arjun!
