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.

Features:
✔ 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.

Edit: I found the pro version for $10 and paid the author some cash, happy to support, he saved me tons of money. Once you get used to the UI, it's amazing. I watched a Best buy product that I had purchased and was able to get a lower price because I called immediately when they lowered the price and did a price match 🙂 so, paid for the $0 that I paid for this app right away 🙂

This app does a good job of checking for changes for part or all of a web page. It does save a record of all of the changes found over time. However, it is not always easy to select the desired part of a web page. Furthermore, the only notifications show up by looking MANUALLY at the notifications through the pull-down display. There are no pop-ups or sounds for any changes found by the app.

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! 🙏
