On many occasions we wants to monitor a webpage or website so that we can keep track it, let say you wants to monitor a news webpage so that if webpage changes and any new news is updated you will get alert so that you can track it.
VisualPing is a new web service which lets you monitor any web page for free and sends email notifications if webpage is changed or any new content is updated.
Unlike other webpage monitor apps this one is quite easy to setup, all you need to do is enter webpage URL and it will generate a screenshot of that webpage, next select an area which you wants to monitor and at the end enter your email address so that you can get notifications.
I had tested this web app on some frequently updated websites like news websites which updated on very frequently basis.
I am quite happy with its results, this apps send notifications in quite minimal manner and sends screen shot of before and after which is very good.
