Page Monitor is a free Android application developed by Mat1ss under the Utilities & Tools category. This app allows users to monitor web pages and track any changes made to them. It is particularly useful for websites that do not have an RSS feed or when changes need to be tracked in a specific time interval.

One of the main features of Page Monitor is its ability to compare web page changes with customizable changes percentage and update interval. If any changes are detected, the user receives a notification. The app also allows for filterable amounts of changes to be tracked, ensuring that users only receive notifications for significant changes.
