This app adds new features Web Alert. Web Alert can monitor your web pages for changes and notify you when a change was detected (e.g. when the price of a product in an online store has dropped).

Main Features
Suitable for everyone:
✔ Set any custom frequency for checks (e.g. every 5 seconds)
✔ Only watch changes in the text between word … and word …
✔ Monitor a number for changes (e.g. the price of a product)
✔ Define a time range without checks or without notifications
✔ Change notification only when a certain keyword is present (or absent)
✔ Access websites with SSL certificate problems
✔ Limit alerts to a minimum change percentage
✔ Modify the URL of trackers
✔ Can notify when a website is down or offline
✔ Export versions as a zip archive

Suitable especially for dedicated users and professionals:
✔ Filter content with regular expressions (RegEx)
✔ Use CSS and jQuery selectors
✔ Watch in HTML source code for changes
✔ Plug-in to integrate with Tasker, Automate and Automagic

Further features will be added automatically. Currently in planning:
• Option to import and export all data
• Option to duplicate trackers
• Android Wear integration so that changes can be seen on a watch
• View changes already in the notification
• Dynamically hide parts of the unchanged text in the changes view
• Other ideas sent to me by users

You must have the Web Alert app installed: https://play.google.com/store/apps/details?id=me.webalert
With the extensive Tasker plugin many parts of the app become programmable even without knowledge of a programming language. You can find details about the Tasker plug-in here: http://webalert.me/tasker

Enjoy these new features! :-)
