Follow That Page is an app (or website) that allows users to track changes to any webpage in real time. It lets users know when any website they are interested in changes, whether it is a news site, a blog, an ecommerce store, or any other page on the internet. The app sends notifications to users as soon as any change is detected, so they can be the first to know when something is updated. The app also provides users with a history of changes, so they can easily compare different versions of the page and see what changes were made. Additionally, Follow That Page allows users to store their favorite webpages, so they can quickly and easily access them from any device, anytime.
