Use This App to Track Changes or Updates on Any Website

If you ever need to keep tabs on small changes to a website, Visual Ping can help. Visual Ping is a website and browser extension that tracks websites for just about any text, visual, and formatting change you specify. In a way, it's like using the Internet Archive's Wayback Machine, only in real time.
