WikiPatroller is an Android app for identifying and reverting vandalism on Wikipedia. It is available for free on Google Play.

Please direct all questions, bug reports, and feature requests to the talk page.


WikiPatroller is available for free from the Google Play store, so it should be quite easy to install. It requires at least Android 3.0 (Honeycomb), and works well on both phones and tablets. The app is, and will always be, advertisement-free.

Using WikiPatroller[edit]

Right now, the app requires the rollback right (request it here). Other than this, there is no approval process.

Once logged in, the app shows a stream of recent changes from whichever wiki you choose ( by default). For each change, it displays the name of the article, the user, the time, the number of characters added or removed, and most importantly, a diff of the edit in question. If you see a disruptive edit, you can choose to either Revert, and provide an edit summary explaining why, or Revert vandal, and use the default edit summary. The Next button shows the next edit.

There is currently limited filtering capability: the app can show either all edits, or only those made by anonymous IP users.

Although designed for (and only tested on) on the English Wikipedia, WikiPatroller should work on all sites running MediaWiki software, including wikis in other languages.
