Things change. On the web, especially, where content is often updated at irregular intervals, it can be difficult to track changes without constantly sitting at the computer and clicking “refresh.” Monitorbook is a web-based application that automates this process and provides users with a way to monitor content on the sites they select in real-time.
Although online prices are the most obvious thing that you’ll want to track with Monitorbook, the application can really be used to track just about any element on any website. Add the Monitorbook bookmarklet to your bookmarks bar to begin using the service. The next time you visit a webpage you’d like to track, click the bookmarklet and the element, or elements, you want to track. Monitorbook will immediately start monitoring the elements you selected, checking for updates every 24 hours or 30 minutes, depending on the membership plan you’ve set up. When the element you’ve selected changes—for example, when a price goes down or when concert tickets become available— Monitorbook will notify you immediately.
In addition to its basic tracking features, Monitorbook also enables users to set up custom alerts. Custom alerts allow for notifications only when certain conditions are fulfilled, such as when a price falls below a pre-determined threshold. Users with free accounts can monitor up to five different elements simultaneously, while users with paid plans can monitor up to 50.

What we didn’t like:
The price of $49 seems high to me. Also it appears a bit exaggerated to say that one can track “anything on the web” because it is not able to track my grades on my school’s website because you need to enter your username and password, which the web app cannot handle (the android app “Web Alert” can do that and it is free). I hope they could add this feature also and lower a bit the price 🙂
