About this app

Web Alert lets you monitor any website (or specific parts of it) you wish in order to be notified when it is updated. It even works when a login, a form post or password prompt is necessary to access the site. For example, get notified when a price changes, a new article is published, you receive exam results or an answer in a forum, a registration period has opened, etc. You can also check if your own website is currently online and working correctly, or use it for UI testing and web monitoring.

You navigate with its special browser to the webpage and the app tracks your navigation steps so that these can be repeated later in the background automatically. On the page you select the text (or HTML) visually that you want to watch for updates so you receive only notifications for modifications in these parts. The alarm report of the checker highlights the differences.

Other apps only automate checking repeatedly the raw content behind a simple URL. This app, however, also features Web Automation where instructions (macros) are recorded interactively. Your actions to reach the website (and your selection of the text whose updates you want to keep track of) are replayed automatically in intervals specified by you. This gives you the additional opportunity to oversee alterations in Deep Web pages.

The app allows you to be the first to know about changes and news. It can save you time and money and the burden to remember checking in on web pages frequently yourself.

✔ Notification when a website changes
✔ Monitor various websites on the watchlist
✔ Simplified way to give instructions for checking
✔ Visual difference of all modifications to a website detected (diff)
✔ It can act as a web monitor to check the availability and correctness of your homepage
✔ Choose exactly which parts of a page to watch
✔ Save mobile traffic by disabling or reducing checks for mobile networks
✔ Check pages even behind logins, HTTP Authentications, form posts or long navigational sequences
✔ Monitor websites with JavaScript
✔ 256-Bit AES-encryption for all sensitive data
✔ Notification alarms using sound, vibration and/or the LED
✔ Browse the different versions of a website (includes offline browser)
✔ Requires only a minimum amount of permissions.

This project was developed as part of a thesis at the University of Hamburg (Germany). Some modern websites with too much JavaScript do not work properly yet, please have patience.

Nice app overall. It'd be nice for there to be an option to only run check if phone is charging/charged. Similar to check frequency, there could be a default global option that's overridable per check. Should have option to disable caching for all checks. Nice feature would be to fine tune metered connection handling so that this could be set on a per alert and not per app.

Awesome app but is there a way to blacklist changes and make multiple individual selections? I have an issue with a specific link for a product that at random times redirects to the Websites homepage and Web Alert detects this redirect as a 99.9% change and usually after another scan reverts to the original link that was meant to be scanned(a blacklist option would be useful here).

Stopped working. I don't get it. I installed it and set up a few alerts and it worked fine (manual & automatic). A couple of hours later, it appears that the alerts I set up are dimmed and I can't get them to run manually or automatically. And no matter what I try I can't uncheck the "Checks during Standby" box. When I try it just takes me to a list of battery optimized apps. I've tried every setting, and cannot get it to update any of the alerts on the list. I liked it when it worked.
