Following a limited product offer on a website, following new comments on a blog, or the latest news in a specific category in an online newspaper are some of the reasons why you might want to monitor website changes from your cell phone..
To be able to track or trace the changes that are generated on a web page from an Android cell phone, simply install an application such as Web Alert (Website Monitor) , which can be downloaded from the Play store , which generates notifications in the device every time it detects a new change in a web page indicated by the user.
This application allows you to monitor changes in an entire web page and also changes in a specific section of a page. It allows, for example, to follow the complete price page of a product on Amazon or Mercado Libre, but it can also help detect changes in a specific offer on that page, to see if its price is reduced..
Using the built-in browser in Web Alert you have to go to the page you want to monitor. Touch on the approval at the top to mark the zone, area or section of the page that you want to monitor and click again on the approval to finish. If you want to monitor the entire page, you just have to double-tap on the go-ahead.
Monitor only a section of the web page..
When there are changes to a page, the application warns by generating a notification on the Android cell phone. These can also be seen by entering the application. By tapping on the page with new changes, you can see exactly what changed on it: if text has been deleted, it will appear in red and if new text has been added to the page, it will appear in green.
Detail of changes in a web page. Content removed in red and content added in green.
Web Alert also allows monitoring URLs with a login in between, that is, the user can monitor changes in their email inbox or, in general, any page that needs to be entered using a username and password. .
If the phone is connected by Wifi, the application monitors every 3 hours if there are changes in the web pages added by the user, but this frequency can be changed in the app settings. This parameter can also be adjusted for each page separately.
