About the product
PageLens is a Chrome extension for following meaningful changes across websites. Open a page, describe what you want to track in plain language, and set a check schedule. Results are collected in one readable timeline, so you can follow product prices and stock, relevant new posts, or other changing information without refreshing each page yourself.
It supports cloud checks and an optional macOS local service. A free plan is available, with paid cloud capacity available separately. Access to signed-in pages requires permission for that site. Checks stop at CAPTCHA, MFA, device confirmation, or expired sign-in. Page compatibility can vary, especially on complex sites.

For product owners
Promote PageLens
Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps PageLens in front of people instead.
- Back in the X and Threads rotation: PageLens gets posted again instead of once.
- A promoted slot on the AppRater homepage, carrying a Promoted badge.
- A direct link to PageLens from a DR41 site (Ahrefs Domain Rating), with no redirect in between.
- A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
- Stays on the first screen however old the listing is, while new submissions push everything else down.
