Japanese developer ZOKUZOKU has introduced a new browser extension aimed at reducing screen time, complete with an endearing element.

When social media users scroll for too long, a large, orange cat appears, blocking access to the current site in use. The extension, known as Cat Gatekeeper, is available for free via the Chrome web store, as reported by Dexerto.

Users can establish limits for their social media usage, with a default setting of 60 minutes, as well as the length of breaks, which default to 5 minutes. Once the usage limit is reached, the orange cat overlays the screen, lies down, and prevents access to the site until the break has elapsed.

The time only counts if a social media app is active, and if another tab or app is opened, the timer will reset.

In the overview for the extension in the Chrome web store, the developers state that it is for people who "keep opening social media without thinking … suddenly realize an hour has passed, [and] willpower alone just isn't cutting it."

As technology becomes increasingly embedded in daily life, developers are creating various tools to assist people in managing screen time more effectively.
