Do you need to check a web page or a local file frequently, looking for changes in them? You know it's boring, error prone and a real waste of precious time.

Several web sites offer RSS feeds, but they do not necessarily cover the type of information you are looking for and there aren't many tools to check local files.

Changes Meter performs this exact job and it will notify you whenever something happens, you can even decide how extensive the change must be before it triggers a notification.

Requirements:
OS X 10.7.5+
