Web Alert (Website Monitor)

Web Alert (Website Monitor) is a website monitoring app that notifies you instantly when any webpage you're watching changes. Unlike basic URL checkers, this app records your navigation steps—including logins, form submissions, and multi-step sequences—then replays them automatically in the background so you can monitor content behind authentication, JavaScript-heavy sites, and complex navigation paths.

Stay ahead of updates that matter to you. Get notifications when prices drop, new articles publish, exam results arrive, forum replies appear, registration periods open, or any other change occurs on pages you care about. You choose exactly which text or HTML sections to monitor, so you receive alerts only for the modifications that matter—not every minor page update. The visual difference report highlights precisely what changed, saving you time scrolling through pages manually.

The app's intelligent approach to web monitoring sets it apart. You navigate to any webpage using its built-in browser, and Web Alert records your actions automatically. This "web automation" feature means you can monitor pages that require logins, HTTP authentication, or lengthy navigation sequences—even deep web content that standard monitoring tools can't reach. Once your monitoring instructions are saved, the app repeats them at intervals you set, checking for updates without manual intervention.

Business owners and IT professionals benefit from built-in website uptime monitoring. Check if your own site is online and functioning correctly, or use Web Alert for UI testing and continuous web monitoring. Mobile users appreciate the option to disable or reduce check frequency on mobile networks, preserving data while staying informed.

Security is built in. All sensitive data—including login credentials and monitoring configurations—are protected with 256-bit AES encryption. The app requires minimal permissions and respects your privacy while working quietly in the background. Customize notifications with sound, vibration, LED alerts, or silent updates depending on your preference.

Browse previous versions of monitored websites directly in the app's offline browser, letting you compare changes side-by-side. This thesis project from the University of Hamburg combines academic rigor with practical utility, though some modern JavaScript-heavy sites may have limited compatibility.

Web Alert (Website Monitor) transforms passive web browsing into active intelligence gathering—be the first to know about changes that matter.
