The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About PageSignal

PageSignal is a private website change monitor for Chrome. Track pages you care about — competitor sites, pricing pages, product pages, documentation, job postings, or any page you check repeatedly. PageSignal checks selected pages at configurable intervals and sends desktop notifications when changes are detected. Unlike server-based monitoring tools, PageSignal runs in your own browser. The pages you monitor and their content stay on your device. Use PageSignal to: • Monitor competitor websites and landing pages • Track pricing page changes • Watch product pages, docs, and release notes • Get notified when important pages change • Avoid manually checking the same pages again and again Free plan: monitor a small number of pages locally. Pro plan: higher-frequency checks and support for JavaScript-rendered pages.
