Web Alert lets you define alerts to notify you immediately when a webpage element changed to a particular value.
You can set alerts for product prices, news, exam results, concert dates etc.

You can track sections of a webpage which you select with a build-in selector similar to jQuery or CSS selector.

You can interpret the selection in three ways:

• as a text
• as a number
• as a date

You can use regular expressions, in a Search and Replace, to extract just the useful information from the selected elements.
