Change Detection

Automatically track website changes in background

Change Detection tracks changes on websites you otherwise would visit frequently to see if there is something new. Use cases:

  • Teacher says grades will be published "soon", but no one knows what "soon" means and you are tired of reloading.
  • You are working with a server and wants to know the result from a request, periodically.
  • You are waiting for updates on an Exam, like if something was postponed or updated.
  • You want to monitor the Dagger documentation to see when Thermosiphon’s explanation improves.


Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
