Kiwix is an offline content reader which can be used to download and browse Wikipedia as well as other sources (Ubuntu documentation, WikiLeaks, WikiSource, WikiVoyage, etc).
Once you download the content file (potentially very large), you don't need any connection to use it.
The app is a lightweight piece of software reading ZIM files stored on your device or external storage (SD card).
Please read the instructions inside the App or on the website to learn about the various content that we offer.
Note: Kiwix is also available on regular computers (Windows, Mac, Linux).
