Breathing Reminder is a free Chrome extension designed to promote mindfulness by encouraging users to take regular breathing breaks. It utilizes the box method of breathing, which consists of inhaling for 7 seconds, holding the breath for 7 seconds, exhaling for 7 seconds, and then holding again for 7 seconds. This structured approach aims to help users calm their minds amidst the bustle of daily life.

The extension allows for customization, enabling users to set their preferred reminder frequency in minutes, with a default setting of once per hour. This flexibility makes it easier for individuals to integrate mindful breathing into their routines, ultimately fostering a more relaxed and focused state of mind while using their browser.
