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.

I LOVE THIS APP. I lost my chance to pre-order a particular item I wanted very badly, but there was a chance they might open it up for a few more pre-orders at a random date. Sure enough after 2 months of this app running in the background without any noticable battery drain, it alerts me tonight and I got the the item. You guys rock. Edit: what do you know, the item instantly is out of stock again a few minutes after going up. I truly wouldn't have had a chance without this! 🙏

Edit - Developers fixed the issue! Fast response time! I used to love this app. It worked great for checking for changes in websites. But starting the past few days, the app has stopped automatically checking. I've tried changing the settings, reinstalling, etc., but it won't automatically check in the background. That defeats the purpose of this app. Please fix. I was really relying on this app and it was amazing before

I am very sorry about Web Alert not updating automatically lately. I would like to apologize for the inconvenience and possible confusion! The problem is fixed now in the newest version and should not happen again.

So useful & easy. All one has to do is share a web page to the app. Or paste the web page URL into the app. One can specify which part of a web page to monitor, or be notified of any changes. The app reports on the amount of change as a percentage. One can check every half hour hour, or less often, according to user preference The premium version provides additional options and abilities. I use it so I don't miss a sale where the good stuff get snapped up fast. Highly recommended!
