TrackFyre: Users select a component of a website that they want to track changes in (using a Chrome extension). Our app sends the user an email when the component changes.

Cool features: User friendly interface - selecting a section of a website is as simple as clicking on it! Robust - If the component selected moves around in the page, our app still tracks changes in the component.

Sample use cases: Tracking product prices on Amazon. Checking for a star's profile update. Updates to a product catalogue. Notified when an appointment slot (in say a clinic) opens up.
