Search for a website watcher app and you will find that WebSite-Watcher already has one. Aignes, the company behind the Windows program, offers a free WebSite-Watcher App for Android and iOS. So the real question is not whether you can watch a page from your phone. It is where the checking happens, and what that means for battery, coverage and the alerts you get.
What the WebSite-Watcher App does
The app is free and needs no account. You add a page or an RSS feed, and the app checks it and highlights the text that changed. You can set ignore filters so a rotating banner or a timestamp does not count, and you can highlight keywords you care about.
Aignes describes it in four words: runs on your phone, no cloud. Everything is stored on the device. If you also own the Windows version, the app can read the bookmarks it monitors, synced through Dropbox.
That is a tidy setup for privacy. It also means the phone is doing the work. The checks run from your device, on the device's terms.
What a cloud app does instead
AyeWatch also has iOS and Android apps, plus a web app, but the checking runs on its servers. Your phone receives the result. Close the app, put the phone in airplane mode on a flight, and the monitor keeps going; the alert is waiting when you land.
The other difference is how you tell it what matters. In AyeWatch you write a sentence:
- "Tell me when this venue adds a new date in my city."
- "Let me know if the sold-out size comes back in stock."
- "Alert me when registration for the spring league opens."
A model reads each change and only sends a push notification when it matches. A new photo in the header does not trigger anything, and you do not need to build an ignore filter for it.

Things people watch from a phone
These are the kinds of pages people tend to follow away from a desk:
- Ticket and event pages for a band or a team
- Shop pages for a restock or a price change
- Game news pages for patch notes and event dates
- School, club or city pages for sign-up windows
- Rental listings in one neighborhood
For the topic side, AyeWatch can watch a subject rather than a page. Ask it to follow news and Reddit chatter about a game's next season, and it will summarize what it finds across sources you did not have to list.
A quick test with one page
The easiest way to feel the difference is to run both on the same page for a few days. Pick something that changes often but only matters sometimes, like a shop's product page where the reviews section updates daily but the price rarely moves.
In the WebSite-Watcher App you would add the page, then build an ignore filter for the reviews block so it stops flagging every new comment. When the price changes, the app highlights the new text the next time it checks from your phone.
In AyeWatch you would paste the same page and write "tell me if the price drops below what it is now or the item goes out of stock". New reviews pass without a ping. When the price moves, a push notification arrives with a one-line summary, even if your phone was in a drawer when the check ran.
Cost, honestly
The WebSite-Watcher App costs nothing and keeps everything local, which is hard to beat for one or two pages. AyeWatch's Free Preview is a trial: three lifetime monitoring runs across up to three topics, checked daily or slower, with no card. After that, Pro is $9 a month and Pro+ is $19. Plans are billed in monitoring credits, where most checks cost one credit, so watching more pages more often uses more of them. Push alerts and the feed come with every plan; email, Slack and Discord delivery are on paid plans.
Which to install
Pick the WebSite-Watcher App if you want a free, account-free tool and you are fine with your phone doing the checking. Pick AyeWatch if you want checks to run whether or not your phone is awake, and you would rather write one sentence than tune filters. You can set up your first AyeWatch monitor from the app in a couple of minutes and see which alerts you actually open.
